Prepare your driveway for snow removal in Oshawa, and the nine checks that decide the winter

Three municipalities in this service area run a snow clearing assistance program, and the two that charge nothing are the two that close first. That ordering is not an accident of administration. A free program has to cap its intake before the season starts, because its cost is fixed by the number of households on the list, and a paid program can keep taking money for longer.

The table below was read on October 9, 2026 off each municipality's own page. The three are published by Oshawa, by Whitby and by Clarington respectively. Nothing in it came from a contractor, a directory or a news story.

Here is the part that costs us money to write down. If somebody in the household is 65 or older, or has a disability a doctor will certify, apply to the municipal program and do not buy anything from anybody until you have seen how it performs. In Oshawa and Whitby it costs nothing, and nothing is a price no contractor in this region can beat. The honest limit on it is also worth knowing: every one of these programs clears the windrow and the public sidewalk and not the driveway itself, and every one of them has a depth below which nobody comes. A 12 cm snowfall in Clarington leaves a windrow the program will not touch, because the threshold there is over 15 cm.

The three sets of rules are collected town by town in our guide to windrow clearing across Durham Region, which carries the eligibility tests in full.

Most driveway markers in Oshawa are installed in the one place the by-law does not allow a post. Boulevard By-law 136-2006, section 3.1.1, bars a hedge, shrub, tree, planting, post, fence, wall or other thing within 0.6 metres of either side of a sidewalk, within 1.2 metres of the curb or travelled portion, or within 1.8 metres of the curb where there is no sidewalk. The same section caps anything on the boulevard at 0.9 metres above grade and refuses anything protruding, sharp or dangerous.

Put those distances on a typical frontage and the arithmetic settles the question. On a 1.5 metre sidewalk set 1.5 metres back from the curb, the 1.2 metre band off the curb and the 0.6 metre band off the sidewalk meet in the middle with nothing left between them. The drawing above is to scale, at 40 pixels to the metre, and the measurement is worth doing on your own frontage because boulevard widths in Windfields are not boulevard widths in the older grid south of Bloor Street.

The reason to care is money rather than tidiness. Oshawa Encroachment By-law 177-2022 puts that risk on the homeowner at section 5.2, which removes City responsibility for damage done to an encroachment by its own operations and names ploughing among them. The City puts the same point in plain words on its snow clearing help page: should damage occur to items found within those guideline distances, the onus for repairs will be on the property owner. A snapped marker is a trivial loss. A decorative boulder, a low wall or a run of landscape lighting in the same band is not.

Spacing, height and the two places a marker earns its keep are covered in detail in our guide to driveway markers for snow removal in Oshawa. The short version is that the markers belong on your own land, above the street line, and the street line is further back from the road than almost anybody assumes.

Pile the snow on the right hand side of the driveway as you face the street, and that is the City of Oshawa's own guidance rather than a contractor's preference. The mechanism is simple once somebody says it out loud. A plow working your side of the road carries its load to the right as it travels, so snow stacked on the left side of your driveway sits directly in the path of the next load, and the blade pushes the whole lot back across your apron.

Two limits bound the decision. The first is Winter Access By-law 92-2009, section 6.1, which makes it an offence to move snow or ice off private property onto a highway or a sidewalk, or to pile or redistribute it there, and section 6.2, which bars putting snow on any boulevard other than the one beside your own lot. The second is the sight triangle. Under Fence and Sight Triangle By-law 23-2014 the driveway version runs 3.0 metres along the street line and 3.0 metres up the side of the asphalt, and section 4.6 holds everything inside that wedge to 0.9 metres. A snow pile is a thing inside that triangle, and on a corner lot the triangle is 6.0 metres on each lot line rather than 3.0.

Where the snow goes once it leaves the asphalt is the whole subject of our piece on snow plowing in Durham Region, including what happens on a property that runs out of storage in February.

There is no published frost depth for southern Ontario, and the number most people quote is from a table about foundations. The Ontario Building Code, Division B, article 1.1.2.2, says the depth of frost penetration is to be established on the basis of local experience and states no figure anywhere. The 1.2 metre number that circulates is the minimum depth of a foundation in clay or in soils not clearly defined, from Table 9.12.2.2, which is a requirement about footings rather than a measurement of frost. The Ontario Ministry of the Environment goes a step further in its design guidelines for sewage works and says frost depth depends on the freezing index, on frost susceptibility and on the thermal conductivity of the soil, and it reserves its extra drainage requirement for places with a design freezing index at or above 1,800 freezing degree days Celsius. The 1991 to 2020 federal normal for the Oshawa station is 439 degree days below zero Celsius a year. This is not a severe frost climate by Canadian standards and it does not need to be, because what damages a driveway edge here is not depth.

What does the damage is silt and water, and the City of Oshawa scores it that way in its own engineering standard. The Design Criteria Manual classifies subgrade frost susceptibility by percentage of silt and by percentage of very fine sand plus silt, and rates a subgrade from 51 to 100 per cent silt as unacceptable. Note what is not on that scale. Clay is not the test.

That matters locally because this city is not one soil. The federal soil survey puts Bondhead, a well drained loam till, under central Oshawa, and Brighton, a well drained fluvial sand and gravel at 87 to 98 per cent sand, under parts of the north and east. Cross into Whitby and the survey returns Darlington, which the same source classifies as imperfectly drained, meaning water is removed slowly enough to keep the soil wet for a significant part of the growing season. A silty to loamy till that holds water and does not shed it is the combination that lifts, because frost heave needs a frost susceptible gradation and available water at the same time. A sand and gravel frontage in north Oshawa and a wet till frontage in Whitby will behave completely differently in the same week of weather, which is why a single rule of thumb about Durham clay is worth very little.

The practical conclusion is modest and it is the honest one. Fix the drainage you can see, fill the cracks that will hold water, and do not pay anybody to chase a frost depth number that no public document contains. What a plow can and cannot do to asphalt, interlock and concrete is set out in our piece on snow plow driveway damage in Oshawa.

In Oshawa there is no on street parking from 2 a.m. to 6 a.m. between December 1 and April 1, and the ban applies whether or not it has snowed. The City states that vehicles may be ticketed or towed regardless of weather or snow accumulation, and that occasional use parking permits are suspended during salting or snow clearing.

This belongs in an October checklist for one reason. If the household has more vehicles than the driveway holds, the answer is a parking decision taken in October and not an argument at 2 a.m. in a snowstorm. It also changes how the driveway should be laid out: the vehicle that leaves first in the morning parks nearest the street, because the alternative is shuffling the cars in the dark to get one out.

Clarington runs a different rule, with no parking on the road between 3 a.m. and 5 a.m. or for longer than three hours, so a Bowmanville or Courtice frontage is working to its own clock.

Oshawa publishes clearing targets rather than promises, and they are useful numbers to hold in your head before you make a phone call about your street. The City snow clearing page sets out a four phase cycle: primary arterial and collector roads, then residential roads, then City sidewalks, then the properties in the assistance program, and a fresh accumulation restarts the cycle. Its published targets are 6 hours on an arterial, 12 hours on a collector and 16 hours on a residential road, against a network it describes as more than 500 kilometres of primary roads, 765 kilometres of residential roads and 160 kilometres of sidewalks. The Region of Durham maintains every Regional road inside Oshawa, which is why the street you turn onto is often cleared long before the one you live on.

Two published numbers in this region do not agree, and this article is not going to pretend they do. The Region of Durham stated in a news release that its equipment is dispatched once four centimetres has accumulated on road surfaces. The Town of Whitby reproduces the provincial Minimum Maintenance Standards with different figures entirely, at 2.5 centimetres for a Regional road and 10 centimetres for a residential street. We could not read the regulation itself to resolve the conflict, so both readings are reported here with their sources attached and neither is presented as the rule.

None of it touches the windrow. Every municipality in this service area treats the ridge the plow leaves across a driveway as the property owner's responsibility, and Oshawa adds that raising or lowering the blade will not prevent it. That ridge is the single item on this list that no amount of preparation removes. It can only be cleared, by the household or by somebody the household pays.

1. Check the programs first. If anyone in the household is 65 or older or has a certifiable disability, apply to the municipal program before you price anything else.
2. Walk both edges and write them down. Note the lip where turf has crept over asphalt and the corner at the sidewalk.
3. Set the markers on your own land. Above the street line, clear of the 1.2 metre curb band and the 0.6 metre sidewalk bands, under 0.9 metres tall.
4. Request a locate if you are driving anything into ground you have not opened before. It is free and it takes five business days.
5. Choose the pile side. Right hand side facing the street, nothing over 0.9 metres inside the 3.0 metre sight triangle.
6. Clear the catch basin while the blockage is still leaves.
7. Fill the cracks that hold water and fix the drainage you can see, rather than chasing a frost depth that no public document publishes.
8. Move the planters, the solar lights, the hose and the net, and settle where the bins will stand at ground level, 30 centimetres back from the curb.
9. Settle the overnight parking before December 1, and settle who clears the sidewalk by midnight of the day after a snowfall.

Andrew owns Northline Property Care and does the work himself, on a fixed local route through Oshawa, Whitby, Courtice, Bowmanville, Clarington, Ajax and Pickering, fully insured. The nine checks above are the ones he walks on a property before it goes on a winter route, and they are written out here so a household can do them without him. He brings six winters of clearing snow in Durham Region to them, and that tenure is his own rather than the company's.

Every figure here was read on October 9, 2026 from a municipality, a region, a provincial ministry, a federal agency or a utility, and each one carries a link to the page it came from. Not one number in this article came from another property care company. Anything in it that turns out to be wrong gets fixed fastest if you phone or text 905-244-5779 and say so.
