Where to put snow from your driveway in Oshawa, and the 0.9 metre line nobody mentions

Start with the only number on this page that somebody can be ticketed over. The City of Oshawa publishes a Fence and Sight Triangle By law, 23 2014, and its section 4.6 sets a single height for everything standing inside a sight triangle, whether that is a corner one or a driveway one: no fence, no natural feature, no thing and no object above 0.9 metre, anywhere outside the central business area. Read the list again. Things and objects. A by law drafted for hedges and lattice fences catches a February snowbank without ever using the word snow, because a snowbank is a thing that stands in a place.

The two triangles are defined in the same document and they are small enough to pace out. Section 1.6 sets a driveway sight triangle as the space bounded by the street line, the side of the driveway, and a line joining points 3.0 metres from where those two meet. Section 1.3 sets a corner sight triangle at 6.0 metres along each street line from the corner. So on an ordinary Oshawa frontage there are two driveway triangles, one on each side of the apron, each of them three paces by three paces, and on a corner lot there is a third that is twice as long on each leg.

Three paces by three paces, nothing over knee height on an adult. That is the whole rule, and it is the part of snow storage that has an enforcement mechanism behind it rather than a preference. Height inside a corner triangle is measured from the grade of the centreline of the abutting street, which matters on the streets north of Taunton where front lawns sit above the road.

Here is the honest limit of it. Outside a sight triangle we could find no Oshawa by law and no Durham Region by law that sets a maximum height for a pile of snow anywhere. You may build a snowbank as tall as you can throw it in the middle of your own front lawn and nothing in the by law library has an opinion. The rule exists where somebody pulling out of a driveway needs to see a child on the sidewalk, and it stops there, which is a sensible place for a rule to stop.

What makes this worth knowing in October rather than in February is that nobody builds an illegal pile on purpose. The pile at the apron starts at ankle height after the first storm, and it gets there because the apron is the shortest carry from wherever the shovel is. By the third storm it is at the knee, and by the fifth it is above the hood of a car and the driver backing out is looking at a white wall. The decision that produced it was made in November and it was never actually made, it was just the first place the snow went.

Northline serves five municipalities and they publish five different positions on the strip of grass between your lawn and the curb. This is the single most useful finding on the page, because almost every piece of advice on the subject assumes there is one answer. There is not.

Whitby is the clearest. Its own page says to pile snow on your property or on the boulevard, and its Property and Boulevard Maintenance By law, 6937 15, prohibits placing snow on the travelled portion of a highway and says nothing at all about the boulevard. A Whitby resident who moves the windrow back onto the grass strip is doing exactly what the Town asked.

Pickering says both things in the same week. One City page tells residents they are required to shovel the windrow onto their boulevards and not back onto the road. Another City page tells them to pile it on their property and not throw it back onto the sidewalk or street, and adds that the City owns the boulevard area and will repair with asphalt any damage its ploughs cause there. The two pages are not reconcilable as written, and a resident following either one in good faith is following the City.

Ajax never mentions the boulevard and is the strictest of the five on everything else. Section 5.4 of its Public Nuisance and Safety By law, 46 2025, bars shovelling, ploughing or blowing snow off any property and onto or across four named things: a roadway, a sidewalk, a pedestrian walkway, or another property, in every case without authorization. Another property is the clause worth noticing. In Ajax, blowing your driveway so the stream lands on the neighbour's lawn is named, and so is blowing it across the sidewalk even if the snow comes back down on your own grass.

Clarington publishes a single sentence on its winter road maintenance page: do not push, plough or blow snow onto the road. Nothing about the boulevard either way.

Oshawa is the one that cannot be read literally. The Winter Access By law, 92 2009 as amended by 11 2016, bans at section 6.1 the moving of snow off private property and onto either a sidewalk or a highway, and the definitions at section 2.1 state that highway here takes in any boulevard. Taken on its own that prohibits piling snow on any boulevard anywhere, including the one in front of your own house. Section 6.2 then bans putting snow on any boulevard that is not next to your own lot, which only makes sense as a rule if the boulevard that is next to it is permitted. Both clauses cannot be true at once.

The City resolves it the strict way on its own public page, which tells residents to put the snow from the driveway and the sidewalk onto their property rather than the roadway. Two pieces of practical advice sit beside it. Keep the heap on the right hand side as you look out at the street, because that is the side a passing blade reaches last. And push snow back onto the lawn to improve what you can see when you pull out. Nowhere does Oshawa invite anybody to use the boulevard, and that is the difference between it and Whitby.

The penalties sit at the back of the Oshawa by law and they are not nominal. Administrative penalties run at $75, $175 and $275 by tier, and the offence provision carries a fine of not less than $300 and not more than $5,000 on a first conviction. In Ajax, sidewalk fines start at $150 and are applied to the property tax bill, which is a quieter enforcement route and a more effective one.

So the one sentence that is correct in all five towns is the conservative one. Put it on your own property, back from the street line, and the question of who owns the grass strip never comes up.

The hydrant, the gas meter and the foundation, in that order of consequence. None of the three is obvious from the driveway, and all three are routinely buried by somebody who was concentrating on getting the car out.

The hydrant first. In Oshawa the hydrants belong to the Region of Durham, and the City asks the households and businesses beside them to take the snow back two feet, far enough that the hydrant can still be seen from the road. Note the word asks. There is no clause in the Winter Access By law requiring it, and we could not find a numeric clearance anywhere in the Ontario Fire Code. The Ontario Association of Fire Chiefs states plainly that there are few rules about who should clear hydrants, that it is generally considered the property owner's responsibility, and that fire officials recommend at least one metre of clearance. Waterloo Fire Rescue publishes 1.2 metres on all sides. Three different numbers from three sources, none of them provincial law, and the smallest of them is Oshawa's own.

The honest way to hold that is as a judgement rather than a rule. A crew arriving at three in the morning needs to find the hydrant from the truck and then get a wrench onto it. Two feet makes it visible. A metre makes it workable. If the hydrant is on your boulevard, clear the metre and stop arguing about which document says what, because the cost of being right is measured in minutes and the cost of being wrong is measured in a house.

The gas meter second, and this one is a safety instruction rather than a preference. Enbridge Gas publishes that snow, ice or debris around a meter or its vents can prevent proper gas pressure regulation, damage gas piping and increase the risk of a leak, block appliance vents causing malfunctions, and lead to carbon monoxide entering the home. The instruction is a broom or a soft brush after every storm, never a sharp object, never a shovel and never a blower on the meter or the vents, and no attempt to break or melt the ice. Enbridge asks to be called at 1 877 542 2630 to deal with icing buildup, which is a free service most people do not know exists.

The same page carries a line aimed squarely at this article: if your meter is near a sidewalk or driveway, make sure it is visible to anybody operating a plough. On a Durham sideyard the meter is often within a metre of the driveway edge, which puts it exactly where the pile wants to go and exactly where a blower discharge chute points if the operator is working away from the house. It is also the one item on this list where the failure mode is not an inconvenience.

The foundation third. The grade around a house was built to shed water away from the wall, and the City of Pickering engineering design criteria for lot grading are the clearest local statement of what that means: positive surface drainage at a minimum of 2.0 per cent away from all buildings, and a minimum 0.6 metre wide apron sloping at 2.0 per cent away from the foundation wall. The National Building Code requires backfill graded to prevent drainage toward the foundation after settling, and a site graded so water will not accumulate at or near the building, though it states no percentage.

A pile of snow stacked against a basement wall is a deliberate reversal of that design. It sits on the 0.6 metre apron that was built to move water away, it holds a month of precipitation in one place, and it releases it at the wall in March when the ground below is still frozen and has nowhere to take it. Keep the pile off the first stride out from the wall and the apron does the job it was graded for.

Every grain of salt spread on a driveway between November and March leaves in the melt, and most of it leaves through one spot. That spot is wherever the snow was piled. It is the reason a lawn can be uniformly healthy except for one brown scar in the same corner every spring, and it is the single most avoidable damage on this page.

Canada uses about five million tonnes of road salt a year as a de icer, and the federal position on it is more nuanced than either side of the argument usually admits. A Priority Substances List assessment under the Canadian Environmental Protection Act concluded in 2001 that road salts meet the environmental harm criteria in paragraphs 64 a and 64 b of the Act. They were never added to Schedule 1. What arrived instead, in April 2004, was a Code of Practice It applies to organizations that spread more than 500 tonnes in a year, averaged over five. Nothing federal governs the bag in your garage.

The thresholds in that work are the useful part. Chloride concentrations above about 230 milligrams per litre have chronic effects on sensitive freshwater organisms, and 870 milligrams per litre is the median lethal range. For soil the Code names roughly 60 milligrams of sodium and 90 milligrams of chloride per litre as protective. Those are small numbers next to what winter runoff actually carries.

Toronto and Region Conservation Authority monitored 47 stream stations across the Lake Ontario watershed from 2016 to 2020 and published the results. The highest average winter chloride concentration at a single tributary was 2,345 milligrams per litre. In summer, with no salt being applied at all, 32 of the 47 sites still exceeded the 120 milligram chronic guideline. A provincial study in the Journal of Great Lakes Research in 2022, written by Ontario ministry scientists, found mean chloride in monitored urban streams rising from about 111 milligrams per litre in the 1970s to about 273 in the 2010s. None of those readings is from a Durham creek and none of them is from anybody's lawn, which is said here rather than quietly implied.

What happens at the scale of one pile is better documented on the plant side. University of Wisconsin extension puts most de icing salt soil damage within about 30 feet of the treated surface and most spray damage within 60 feet, and explains the mechanism: sodium wrecks soil structure, raises pH and cuts infiltration, while the salt binds water tightly enough that roots cannot take it up, so the plant experiences a drought in wet ground. Purdue measured 890 parts per million of chloride in soil within 30 feet of a highway and noted that this is about ten times the level known to inhibit seed germination and root growth in grasses.

The part that confuses homeowners is the delay. The University of Massachusetts extension states that damage from salt in the soil can be delayed, with symptoms not appearing until summer or even years later, and it names snow piled onto lawns and garden beds as a pathway in its own right. So the brown patch in July is not July's fault, and the cedar hedge that thins on the driveway side over three winters is not a hedge problem.

Two things fix most of it and neither costs anything. Use less salt in the first place, which is a subject in its own right and one we have written about separately. And once the ground thaws in April, flush the pile corner heavily, because the published remedy for salt in a root zone is water: at least six inches of it, applied to move the chloride down past the roots rather than leaving it to be taken up.

Walk it once in October, in daylight, with nothing on the ground, and the decision is made for the whole winter. Here is the order we use when we price a property, and there is nothing in it a homeowner cannot do themselves.

One. Rule out the roadway and the sidewalk. That is provincial law and municipal by law respectively and it is not a judgement call in any of the five towns.

Two. Pace out the two driveway sight triangles, three paces along the street line and three paces up the driveway edge, and mark the apex in your head. Nothing over knee height goes inside either one. On a corner lot pace six along each street line as well.

Three. Find the hydrant, the gas meter and the first stride out from the foundation wall, and rule those out too. The hydrant may be on the neighbour's boulevard, in which case it is still worth clearing and it is still nobody's legal duty.

Four. Work out which way the lot drains, and pick the downhill side of the driveway for the pile. If both sides are equal, pick the side with more lawn behind it, because the pile needs room to spread sideways rather than up as the winter goes on.

Five. Decide where the windrow goes before the first storm, not during it. The windrow arrives after the driveway has already been cleared, which is why it so often ends up in the worst available place: the operator or the homeowner is tired, the car is already out, and the apron is right there.

Six. Write the side down, or tell whoever clears the property, and change it next winter. A property with a note in the file saying the pile goes left does not get a different answer every storm depending on who is holding the shovel.

On a narrow lot this walk sometimes ends with the honest conclusion that there is nowhere good, only somewhere less bad. Ajax says as much on its own winter page, that snow storage availability is very limited in newer communities where narrow lots reduce available space, and anyone who has stood on a thirty foot frontage in north Whitby in February knows the Town is being polite. On those lots the answer is to spread the pile thin and long down one side rather than high and round at the apron, because a low wide pile stays under 0.9 metres and melts faster.

The tier that clears a driveway to the 7 AM target after overnight snow is Gold, and it is $189 a month plus HST. On the card that reads $213.57, and over twelve equal payments it comes to $2,268 for the year. Platinum goes first in the sequence, at a 6:30 AM target, with salting applied automatically and without limit, and the first pick of service day. Memberships open at $129 a month plus HST, and what the entry tier buys is the windrow pass by 5 PM rather than the driveway cleared in the morning, which is the distinction most of this page turns on.

Bought as a season instead of a membership, a standard property is $975 plus HST, a small one is $800 and a large one is $1,200. That price holds until November 1. The residential route itself closes on November 30, and after that a property cannot join for the winter at all. Those are two separate dates and both of them are real.

The snow storage walk described above is part of pricing a property and it carries no surcharge. What comes out of it is a note in the file naming which side the pile goes on, how far back from the street line, and whether the frontage will hold a full winter. On a property where it will not, that is in the quote in writing rather than discovered in January.
