See What a New Detached Garage Costs Before Anyone Visits

Building a 400 sq ft two-car detached garage in Toronto costs about $51,500 to $66,340 CAD before HST at 2026 prices. The low end has vinyl siding and no power, and the high end adds fibre cement siding, lights and outlets, and removal of an old garage.

A detached garage protects your vehicles, stores tools, or gives you work space. Your first choices are the size, the foundation, and how you reach the garage from the street or lane.

What Changes the Cost

  • Site and foundation: Site clearing adds cost, and frost walls with footings cost more than a floating slab.
  • Size and roof shape: More square feet and a steeper roof mean more framing and roofing.
  • Doors and openers: Two single doors cost more than one double door, and insulated doors with openers add more.
  • Electrical and heat: Lights, outlets, and a heater each add to the total.
  • Demolition and drainage: Removing an old garage and fixing drainage add work before the build starts.
