Corner lot snow removal in Oshawa, and the two frontages one midnight covers

Oshawa puts the duty in section 3.1 of its Winter Access By-law, numbered 92-2009, and the wording does the corner lot work by itself. An owner has to clear the snow and ice away from any sidewalk sitting on any highway, and the by-law then names three positions that sidewalk can be in: in front of, alongside, or at the rear of the lot. Those six words are the whole question answered in a sentence somebody wrote in 2009. Read the consolidated by-law yourself if you want it in the original. It is short.

A mid block house touches one highway and owes one run of sidewalk. A house on the corner of a crescent and a collector touches two and owes both. The by-law does not grade the second one as lesser, does not give it a later hour, and does not care that the flanking street has no driveway on it and no front door looking at it.

The part that surprises people is what counts as sidewalk. The same by-law defines it to include the portion that crosses a private driveway, the portion that connects the main sidewalk to the travelled part of the highway, and the portion that connects the main sidewalk to private property. That middle clause is the corner ramp. The flared concrete apron where the two sidewalks turn the corner and drop to the road is not a municipal extra that somebody else sweeps. It is your sidewalk under the definition, and it is the piece that fills first, because it is the lowest point on both runs and the place the blade on the flanking street has the most room to throw.

Clarington is the only municipality in Durham that names this out loud. Its sidewalk snow page tells residents to clear the full width of the sidewalk bordering the property including corner links, which is a better phrase than anything Oshawa publishes for the same object. Oshawa gets there by definition instead, which works in law and fails on a web page, because nobody reads a definitions section before they shovel.

And the deadline is a clock time, not a stopwatch, which is worth about a day

Oshawa does not give you twenty four hours. What it sets is a point on the calendar: the end of the day following the one on which the weather stopped, and that is a different instrument from a stopwatch. A stopwatch starts when the snow stops. A calendar does not care when the snow stops, only what day it was.

Work it through on a real week. Snow ends at one in the morning on a Tuesday. The first day after that is Wednesday, so the deadline is midnight at the end of Wednesday, and you have had about forty seven hours. Now move the same storm nine hours later so it ends at eleven at night on the same Tuesday. The first day after is still Wednesday, the deadline is still midnight at the end of Wednesday, and you have about twenty five hours. Identical sentence, identical by-law, almost double the time, and the only variable is an hour of weather nobody controls.

Whitby, Ajax, Pickering and Clarington all use an elapsed period instead. Whitby asks for twenty four hours from the end of the snowfall. Ajax asks for twenty four hours after a snow fall or ice forming. Pickering writes it into Ice and Snow Clearing By-law 6650/06 as twenty four hours after the accumulation. Clarington asks for twenty four hours after a snowfall ends. None of those four drifts with the hour, and none of them gives a resident forty seven hours either.

The practical reading for a corner lot is to work to twenty four hours and treat the long version as a gift that sometimes arrives. Two frontages on a short clock is the planning case. Two frontages on a long clock takes care of itself.

What it costs when nobody clears it

Section 5.1 of the same by-law lets the Commissioner remove the snow and ice without notice to any owner and at the owner's expense, and section 5.2 makes owners jointly and severally liable for that cost plus interest at fifteen per cent. The administrative penalties run seventy five dollars, then one hundred and seventy five for a repeat inside a year, then two hundred and seventy five. On conviction the fines start at not less than three hundred dollars and run to five thousand on a first offence.

We have never seen a Durham homeowner collect one of those. That is not the reason to clear a corner, and a page that leans on the fine is a page selling fear. The reason is that two frontages of unshovelled sidewalk is where a pedestrian steps into a live lane, and the second frontage is the one nobody watches because the house is not facing it.

Three separate Oshawa by-laws decide where a corner lot pile may sit, and not one of them is the by-law about snow. That is why the answer is hard to find and why most people guess it wrong. The snow by-law tells you where the pile may not go. The fence by-law and the boulevard by-law tell you what is left.

Start with the places that are closed

Section 6.1 of the Winter Access By-law bars moving snow off private property onto a sidewalk or a highway, and bars piling it, redistributing it or otherwise causing it to accumulate there. Section 6.2 then closes the boulevard opposite: snow may not be put on any boulevard except the one next to your own lot.

The trap in that pair is the word highway. The same by-law defines it as the common and public highway including the area between the lateral property lines including any boulevard. So the strip of grass between your sidewalk and the curb is highway for the purposes of section 6.1, and the Boulevard By-law 136-2006 independently makes you responsible for maintaining it. City land, your upkeep, and a prohibition on piling snow on it. A corner lot has two of those strips.

Across the street is closed as well. Section 6.2 exists precisely because the tidy solution at an intersection is to throw the snow onto the quiet boulevard opposite, and that boulevard belongs to the lot it abuts rather than to the person with the shovel.

Then the six by six metres nobody knows about

The City of Oshawa Fence and Sight Triangle By-law 23-2014 defines a corner sight triangle as the triangular space bounded by the two straight lines containing the defining angle of a corner lot, with the points taken at a distance of six metres from where those lines intersect. Section 4.6 limits all fences, natural features, things and objects inside that triangle to zero point nine of a metre.

Section 1.9 carries the clause that almost nobody reads. Inside a corner sight triangle the measurement is taken from the crown of the road rather than from the ground you are standing on, specifically the grade at the centreline of the abutting street. Residential roads are crowned and lots usually sit above the road, so on a typical Oshawa corner your real allowance is less than ninety centimetres of pile measured off your own lawn, and on a lot that sits a foot above the road it can be a good deal less. Nobody is out there with a surveyor's level in February. The useful version is that waist high at the corner is already a conversation and knee high is comfortable.

Here is the honest limit of that argument, and we would rather state it than let the page sound more certain than the law is. By-law 23-2014 regulates fences, natural features, things and objects. It does not use the word snow anywhere. We asked the question directly and could not find any Oshawa instrument that says a snow pile inside the corner sight triangle is a contravention. So treat the six by six metres as the City's own published statement of where a driver's eyes need to be able to travel, which is a very good reason to keep a pile out of it, rather than as a ticket waiting to be written. The City's own winter reminders ask residents to shovel snowbanks at the end of the property farther back onto the land to improve sightlines, which is the same instruction without the enforcement.

And the two bands that decide who pays for the broken edging

Boulevard By-law 136-2006 section 3.1.1 prohibits placing anything within zero point six of a metre of either edge of a sidewalk, within one point two metres of the curb or travelled portion where a sidewalk exists, and within one point eight metres of the curb where there is no sidewalk. Those are not decorative numbers. The City's own snow clearing assistance bulletin says plainly that property owners are responsible for repairing damage to items within those distances, while minor sod damage from City winter operations outside them is inspected and repaired in spring if it is reported to Service Oshawa.

So the decorative stone border a corner lot owner installs forty centimetres off the sidewalk to stop people cutting the corner is, on the day a blade finds it, entirely theirs. We have pulled enough broken landscape edging out of April boulevards in Oshawa and Whitby to say that this single paragraph is the most expensive thing on this page for the people it applies to, and it has nothing to do with snow removal at all until the morning it does.

Encroachment By-law 177-2022 sits behind all of it. It defines an encroachment to include any landscaping, vegetation, natural or artificial object or structure wholly or partly on City owned lands, and its list of exemptions covers boulevard improvements made under the Boulevard By-law and fences that meet the Fence and Sight Triangle By-law. There is no exemption in it for snow, and there is no prohibition on snow either. The by-laws in this area were written about objects that stay put.

What that leaves, on a real lot

Behind the sight triangle, back from both sidewalk edges, and on your own side of the property line. In practice that is the interior side yard, the part of the front lawn furthest from the intersection, and the rear yard if there is a gate wide enough to get to it. On the new lots in Windfields and Kedron, where the Official Plan has been pushing density up for twenty years, the interior side yard is often the only one of the three that exists. On the 1910s and 1920s grid north of the downtown, where the Simcoe Heights plan registered in May 1912 and built out through the thirties, the lots are narrow but the setbacks are deep, and there is usually room at the front.

The one instruction the City does publish, and it is good, is to pile the snow from the driveway on the right hand side facing the street, so the next pass does not push it back in. On a corner lot work out which of your two curbs the blade runs along first, and put the pile on the far side of the apron from it. Half the re-clearing on a corner is a pile placed on the side the plow is about to arrive from. We walk this with every corner lot we quote, and the walk is free whether anybody signs anything. More on where the snow goes is on our page about where to put snow from your driveway in Oshawa.

Oshawa does not plow residential sidewalks, so neither of your two frontages is on anybody's route. This is the single most common misunderstanding we hear on a first call from a corner lot, and it comes from people who moved here from Whitby or Ajax, where sidewalk plows genuinely exist.

The City's published list of what it does clear is short. Sidewalks adjacent to City facilities such as parks and recreation centres. Multi use paths in the boulevard that take the place of a sidewalk. School crosswalks where a crossing guard stands. Sidewalks in the Central Business Improvement Area. Four named trails. And the sidewalks and windrows of residents registered under the snow clearing assistance program. A house on a crescent in Taunton is on none of those lists and never will be.

Whitby does run sidewalk plows, across three hundred and thirty five kilometres of sidewalk, as a tertiary priority after primary and secondary roads. Ajax runs the largest program of the five, clearing about one hundred and fifty kilometres of its roughly four hundred kilometres of sidewalk, primary routes first, and says that can take up to sixteen hours or longer if the snow keeps falling. Clarington plows primary sidewalk routes, pedestrian crossovers and school crossings under a program it launched in 2023 and 2024. In every one of those towns the owner still owes the sidewalk under the local by-law, because a plowed primary route is not the same object as the residential sidewalk in front of a house.

The hours the City works to on the roads

Oshawa publishes targets rather than depths. Arterial roads within six hours, collectors within twelve, residential streets within sixteen, and City sidewalks and school crosswalks by no later than midnight the first day following the end of a storm. The cycle is primary roads, then residential roads, then City sidewalks, then the assistance program properties, and the City states that the cycle starts over if there is new or rapid accumulation. The activity report is updated three times daily during operations.

Sixteen hours is the number that matters to a corner lot, and not for the reason people assume. It is not about when your street gets cleared. It is about when the windrow arrives. A storm that ends at four in the morning can produce a residential pass at any point up to eight that evening, which means a corner lot owner who clears the apron at seven can be doing it again after dinner, on both frontages, and still be inside one deadline.

Those targets sit on top of a provincial floor. Ontario Regulation 239/02 carries the Minimum Maintenance Standards, and it sets how much accumulation a municipality may leave on each class of road: two point five centimetres and four hours on a Class 1, five and six on a Class 2, eight and twelve on a Class 3, eight and sixteen on a Class 4, ten and twenty four on a Class 5. Residential streets in Oshawa are the lower classes, which is why the City's own sixteen hour residential target maps onto the regulation so neatly. Section 16.3 adds the sidewalk standard: reduce snow to eight centimetres or less within forty eight hours of the end of the storm, and provide a minimum sidewalk width of one metre.

Two cautions on that regulation, both of which belong on the page rather than in a footnote. First, section 4(6) of the standard does not apply to portions of a roadway designated for parking, for bicycle facilities or used for snow storage, so a shoulder the plow throws a corner windrow onto may sit outside the standard entirely. Second, we could not open the regulation on the province's own e-Laws service, which would not render for us at all. The section numbers and values above were read off a municipal copy of the e-Laws consolidation dated May 3 2018 and cross checked against four other Ontario municipalities that publish the same table, all of which agree. We cannot tell you whether it has been amended since 2018, and we are not going to pretend otherwise.

Who maintains which road also changes at a corner, and in Oshawa it changes often. The Region of Durham maintains Regional roads all year and patrols them seven days a week in winter. Simcoe, Ritson, Harmony, Wilson, Taunton, Rossland, Bloor, Thornton, Stevenson, Park and Adelaide are all Regional roads along parts of their length. A corner lot where a City crescent meets a Regional road has two different authorities running two different standards past the same house, on two different clocks, and the owner owes both sidewalks regardless.

A corner lot has two boulevards receiving plow spray instead of one, and the salt load on the grass along those edges is the thing that shows up in April as a straw coloured strip the owner blames on the dog. It is not the dog. It is chloride, and the gradient gives it away: the damage is always worst at the hard edge and fades going into the lawn.

The federal assessment of road salts under the Canadian Environmental Protection Act found that aerial dispersion of salt spray extends up to two hundred metres from the edge of a multi lane highway, and thirty five metres from a two lane road where de icing salts are used. A residential corner lot sits well inside thirty five metres of two of them. The same assessment names the mechanism, which is the part worth understanding: the effects are on soil structure, soil dispersion, soil permeability, soil swelling and crusting, and the primary abiotic impact is the loss of soil stability during drying and wetting cycles. Sensitive terrestrial plants may be affected above soil concentrations of about sixty eight milligrams of sodium per kilogram and two hundred and fifteen milligrams of chloride per kilogram. The assessment is published by Health Canada and Environment Canada.

University of Wisconsin extension work puts numbers on how far it reaches on the ground. Most soil salt injury happens within about thirty feet of the road and most spray injury within about sixty feet, with sensitive plants affected a great deal further from major highways. The timing matters as much as the distance: salt applied in late winter or early spring causes the most damage, because plants are most resistant in December and early January and most susceptible in March and April. A University of Minnesota turf trial reports measured concentrations around twelve thousand parts per million of sodium chloride three metres from the road.

What that means for a corner is cumulative rather than dramatic. Two frontages of municipal salting plus whatever you put down on two sidewalk runs plus whatever ends up in the pile means the chloride arrives at the lawn edge from several directions and leaves in one event, when the pile melts. The Canadian Council of Ministers of the Environment sets the freshwater chloride guideline at one hundred and twenty milligrams per litre for long term exposure and six hundred and forty for short term. Those numbers are about the creek rather than the lawn, but in north Oshawa the pile at the corner drains to a catch basin that reaches the Oshawa Creek east branch, so they are not somebody else's problem.

What to do about it, which is cheaper than most people expect

Water the strip heavily in early spring, at least six inches, before you do anything else. That is the University of Wisconsin recommendation and it works by flushing the chloride below the root zone rather than by treating the grass. On the heavy clay soils common across south Oshawa and Courtice, gypsum is the second step, because calcium displaces sodium on the exchange sites and restores some of the structure the sodium dispersed. Then reseed, in April, while the dead strip is still visible and before crabgrass finds the gap. Tall fescue and perennial ryegrass came out most salt tolerant in the Minnesota trial of thirty eight cultivars across fifteen species, and smooth bromegrass, hard fescue and prairie junegrass came out worst at every concentration.

On the de icer itself, less is the whole lever. Rock salt stops being practical around minus nine or ten degrees of pavement temperature, which in a Durham cold snap is most of the mornings you most want it. Calcium chloride keeps working to roughly minus twenty nine and magnesium chloride to roughly minus twenty three, and both are rougher on young concrete. Our page on driveway salting in Oshawa goes through the temperature bands properly. We sell a salt only trip at twenty five dollars plus HST and we would rather sell you one of those than watch half a bag go down on a corner.

South Oshawa, Whitby and Courtice sit largely on the lacustrine clays and clay loams of the old glacial Lake Iroquois plain, and those soils drain slowly. That is not a detail for a gardening page. It is the reason a pile placed on the wrong corner of a Durham lot is still an ice slab in the third week of March while the same pile across town has gone.

The 1956 Soil Survey of Ontario County, which covers Oshawa, Whitby, Pickering and Ajax, names the series and gives each one a drainage class in its own words. Simcoe clay loam, developed on stone free calcareous lacustrine clay, is recorded with both external and internal drainage poor. Peel clay loam, lacustrine clay over clay till at three feet or less, is written up with inadequate drainage named as one of its chief drawbacks. Smithfield clay loam is imperfect. Whitby loam is imperfect. Schomberg has good external drainage and only fair internal drainage. Darlington loam, the better of the group, is good to moderately good. The 1946 Soil Survey of Durham County, which covers Courtice and Bowmanville, places Darlington sandy loam mainly near Courtice and north of Bowmanville with good drainage, and puts Granby sandy loam, poorly drained, in larger areas north of Courtice. The beach ridge of the old lake itself is Brighton gravelly sand, which drains freely.

Here is what we could not do with that, and it matters. The survey maps are scanned images rather than data, so we cannot tell you that Windfields sits on one named series and Donevan on another, and we are not going to guess. What we can tell you is the practical test, which takes no survey at all. Walk your lot after a heavy rain in October and find the place water stands longest. That is the corner the pile must not go on. On a clay loam lot in Courtice or south Oshawa that place is usually obvious and usually close to the street, because the boulevard grade falls to the curb and the lot falls to the boulevard.

One more thing the soil survey explains without meaning to. Salt leaches more easily through sand than through heavy clay, which is why a salt damaged lawn edge on a Courtice sandy loam recovers with spring rain alone, and the same damage on a south Oshawa clay loam needs the six inches of deliberate watering and the gypsum. The soil decides the repair, not the amount of salt.

Oshawa's Traffic and Parking By-law 79-99 prohibits parking within ten metres of an intersection, and up to thirty metres where official signs say so. A corner lot therefore has materially less legal street frontage to park on than the house next door, before a single flake falls.

Then winter takes the rest of it. On street parking is prohibited across Oshawa from two in the morning until six, from December 1 to April 1, and parking is prohibited during plowing and salting regardless of the hour. Whitby, Ajax, Pickering and Clarington all run an overnight winter ban on their own dates, which we set out on our page about winter parking rules in Oshawa. Pickering's set fine for an overnight breach is fifty dollars and ninety for parking during snow clearing, with towing at the owner's expense.

So on a corner lot the driveway has to hold every vehicle on the property, every night, for four months. That is the reason the clearing order on a corner is not the same as on a mid block driveway. The apron and the parking area come first and they come wide, because a vehicle that cannot get off the street at eleven at night is a ticket and a vehicle that is parked badly on the apron at six in the morning is the whole visit lost.

There is a design number behind this too, and it is worth knowing if you are buying on a corner. Oshawa's Engineering Design Criteria Manual requires a minimum clearance of eleven metres from a new driveway to the face of curb of any intersecting street, specifically naming corner lots. That is a standard for new design rather than a retrofit duty, so an older corner lot may sit much closer than eleven metres, and the ones that do are the ones where the windrow and the sight triangle fight each other for the same ground.

The seasonal snow package is eight hundred dollars for a small property, nine hundred and seventy five for a standard one and one thousand two hundred for a large one, plus HST. It covers the driveway, the walkway and the salting, unlimited, at the three centimetre residential trigger, with a seven in the morning target after overnight snow. Book by November 1 for that price, and the residential route closes on November 30. Those are two different dates and both are real: the first is the price deadline, the second is the last day a property can join at all.

Memberships run from one hundred and twenty nine dollars a month plus HST, on twelve equal payments taken on the last day of the month. Here is the part that costs us money to publish, and it matters more on a corner lot than anywhere else. The entry membership does not plow your driveway. It carries a windrow pass by five in the evening and no seven in the morning target. On a corner lot with two frontages, a tight apron, less legal street parking and an overnight ban, a five o'clock windrow pass is very often the wrong product, and we will say so on the call rather than after the first storm. The membership that plows the driveway and carries the seven in the morning target is one hundred and eighty nine dollars a month plus HST. If the honest answer for your lot is that one, you should hear it in October rather than in January.

Two things we price separately and one we do not price at all. A salt only trip is twenty five dollars plus HST. A windrow return trip, which a corner lot needs more often than a mid block driveway because two curbs mean two chances for a second pass, is forty five dollars plus HST. And the municipal sidewalk across both frontages is quoted on the measurement rather than off a table, because the length of the flanking run is the single biggest variable between one corner lot and the next, and a flat rate would be wrong in both directions.

The thing we do not charge for is the walk. Give us the address and we will stand on the lot, measure both frontages, find the sight triangle, find the low corner that must not take the pile, and tell you where the snow is going before anybody signs anything. We do that whether you buy from us, buy from somebody else or do it yourself with a shovel, and on a corner it is the half hour that decides the whole winter. More on the trigger and the route is on our Oshawa snow removal page, and the full windrow explanation is on windrow clearing in Durham Region.

Northline Property Care is Andrew's business, and the person who measures your two frontages is the person standing on them before it gets light. Six winters of clearing snow in Durham Region sit behind this page. The corner lots are the ones you remember, because they are the ones where a plan made in October either holds or does not.

What those winters actually taught about corners has very little to do with equipment. It is that the pile position is the whole job. Put it on the wrong side of the apron and you clear the same ground twice on every storm night of the season. Put it in the low corner and you hand the owner a dead strip of lawn in April and a conversation neither of you wanted. Put it in the sight triangle and a neighbour stops you in the street in January, which is a fair thing for a neighbour to do.

We read the by-laws for this page rather than repeating what everybody says about them, and the two things that surprised us are both in here: that the Oshawa deadline is a calendar date rather than an elapsed period, and that the City's own bulletin puts the repair of anything within sixty centimetres of a sidewalk on the owner. If you take two things off this page, take those, and neither of them is something we sell.
