Service areas
Across the Greater Toronto Area.
Based in Concord and building right across the GTA — from downtown Toronto out through York, Peel, Halton, Durham, and Simcoe.
Where we build
One crew, the whole region.
Alterra is based in Concord, in the heart of York Region, and we build across the Greater Toronto Area. Below are the regions and towns we regularly work in — if you don't see yours but you're in the GTA, ask; we likely cover it.
Toronto
From downtown lots to the suburbs — tight urban builds where every inch of the yard counts.
Toronto · North York · Etobicoke · Scarborough
York Region
Our home turf. Vaughan and Concord out through Richmond Hill, Markham, and Aurora — driveways, patios, and full backyards.
Vaughan · Richmond Hill · Markham · Aurora · Newmarket · King City
Peel Region
Mississauga, Brampton, and Caledon — larger lots and new-build yards that need the whole package.
Mississauga · Brampton · Caledon
Halton Region
Oakville, Burlington, and Milton — established neighbourhoods and detailed stonework.
Oakville · Burlington · Milton
Durham Region
Pickering through Oshawa — pools, patios, and interlock for the east-end GTA.
Pickering · Ajax · Whitby · Oshawa
Simcoe County
North of the city — Bradford, Innisfil, and Barrie, where the yards get bigger.
Bradford · Innisfil · Barrie
