What type of gravel is best for a driveway in the GTA?

Picking the right material for a driveway in the Greater Toronto Area is not simply a matter of choosing what looks good on paper. The GTA has clay-heavy soil, one of Canada's most punishing freeze-thaw cycles, and properties that range from sprawling Vaughan lots to narrow Toronto laneways. Each of these factors changes which gravel performs and which one fails within a season.

Why the GTA climate makes gravel selection different

Ontario winters are not forgiving. Water seeps into an improperly prepared driveway base, freezes, expands, and lifts the surface. When spring arrives, that same ground thaws unevenly, causing rutting, sinkholes, and surface washout. The right Driveway Gravel is one that compacts tightly, resists movement under vehicle traffic, and allows controlled drainage so water never pools beneath the surface.

Rounded, decorative stones fail this test in high-traffic applications. Angular, interlocking materials pass it. That distinction drives every recommendation in this guide.

Granular A: the GTA driveway standard

Granular A is the crushed, angular aggregate specified in Ontario Provincial Standards for residential driveways and interlocking paver bases. It is made from limestone or granite, graded so that particle sizes range from coarse chips down to fine dust. When compacted with a plate compactor, those mixed sizes lock together into a dense, load-bearing layer that does not shift.

For a standard residential driveway in Toronto or Vaughan, Granular A is the base material professional contractors specify first. It handles the freeze-thaw cycle better than most alternatives because the compacted structure leaves little room for water infiltration. Depth matters as well: a properly installed Granular A base should be a minimum of 6 inches for a light-traffic residential driveway, with deeper installations recommended where heavy vehicles are expected.

3/4 Crusher Run: the workhorse surface layer

Crusher Run Limestone (also called 3/4 crush) is a blend of crushed limestone and stone dust. It compacts almost as firmly as Granular A and is widely used as a surface layer in GTA driveways because the fine particles bind together and resist displacement under repeated vehicle traffic.

Where Granular A builds the structural base, Crusher Run finishes the surface. Together, this two-layer system is the most common driveway construction approach used by contractors across Toronto, Vaughan, Concord, Woodbridge, and Scarborough.

The main limitation of Crusher Run used alone as a base (without Granular A beneath it) is inconsistency. Gradation is less standardized than Granular A, which can lead to uneven compaction in high-moisture conditions. For best long-term results, use both layers in sequence.

Limestone Screenings: for under patio stones and bricks

Limestone Screenings (also called 1/4 inch crush with fines) are not a driveway base material, but they belong in this guide because homeowners often confuse them with driveway gravel. Limestone Screenings are used under patio stones, interlocking bricks, and walkways as a bedding layer. They pack very hard and provide a level setting surface.

Do not use Limestone Screenings as a primary driveway layer. They track onto footpaths and roads, and they have limited load-bearing capacity under vehicle weight. They have a specific purpose and perform well in that role.

Pea Gravel: a landscaping material, not a driveway choice

Pea Gravel is a 3/8-inch rounded, washed stone. It is visually appealing, commonly used in dog runs, garden borders, playgrounds, and decorative beds, and it drains exceptionally well. For those reasons it is regularly stocked by Gravel Suppliers in Toronto.

As a driveway surface, however, Pea Gravel fails. The rounded shape means the stones cannot interlock. They scatter under tires, migrate to lawn edges, and create an unstable walking surface. On any driveway with a slope steeper than a few degrees, Pea Gravel will wash downhill with the first heavy rainfall.

Use Pea Gravel for garden paths, drainage trenches, and decorative applications. Use angular material for anything that carries vehicle traffic.

Quick comparison: which gravel for which purpose

Material	Best use	Vehicle traffic	GTA winter performance
Granular A	Driveway base layer	Yes	Excellent
3/4 Crusher Run	Surface layer / base	Yes	Very good
Limestone Screenings	Patio / walkway bedding	No	Good in role
Pea Gravel	Landscaping / drainage	No	Poor on driveways

How much gravel do you need?

Before placing an order, knowing the right quantity saves money and avoids a second delivery. Use the We Deliver Gravel calculator to estimate your project volume based on driveway dimensions and depth.

A standard two-car driveway in Toronto (approximately 20 feet by 40 feet) at a 6-inch base depth requires roughly 14 to 16 tonnes of Granular A. Adding a 3-inch surface layer of 3/4 Crusher Run adds another 7 to 8 tonnes. These are starting estimates; site conditions, existing base depth, and drainage grading all affect the final quantity.

Getting material to tight GTA properties

Many Toronto and Vaughan properties present access challenges that a standard dump truck cannot handle. Narrow laneways, shared driveways, overhead wires, and small backyards are common obstacles in older neighbourhoods like Leslieville, The Annex, and parts of Woodbridge.

For these situations, a Stone Slinger delivery places material precisely where it is needed using a 60-foot conveyor with 180-degree pivot range, without moving heavy equipment onto your property. It eliminates most of the manual wheelbarrow work and protects lawns, gardens, and neighbouring surfaces.

Frequently asked questions

What is the best gravel for a driveway in Ontario?
Granular A compacted as a base layer, topped with 3/4 Crusher Run, is the standard used by professional contractors across the GTA. This two-layer system handles freeze-thaw conditions, vehicle loads, and drainage demands better than any single-material approach.

Can I use Pea Gravel for my driveway in Toronto?
Pea Gravel is not recommended for driveways. Its rounded shape prevents compaction and the stones scatter under vehicle tires. It is better suited to garden beds, dog runs, and drainage applications.

How deep should Granular A be for a residential driveway?
A minimum of 6 inches of compacted Granular A is standard for a residential driveway in the GTA. Driveways that receive heavy vehicles or trucks benefit from 8 to 10 inches of base depth.

Is Crusher Run the same as Granular A?
No. Crusher Run and Granular A are both angular crushed materials that compact well, but Granular A meets specific Ontario Provincial Standard gradation requirements and performs more consistently as a structural base in high-load or high-moisture applications.
