Toronto Garage Door Conversion: Two Doors Into One Wide Door

Updated July 2026

We convert two single garage doors into one wide double door across Toronto: the centre post comes out, an engineered beam replaces it under a municipal building permit, and a custom-width door goes in. Where nothing load-bearing sits above the opening, such as a bump-out or detached garage, the all-in price is $16,000 to $18,000 CAD, with permit fees a few hundred dollars extra. A room above the garage changes the beam design and is priced at the free assessment.

Garage conversions on Toronto homes

Toronto's older neighbourhoods rarely have room for a double garage door at all — narrow lots and detached rear-lane garages were the norm downtown. The two-single-door layout this service is built around shows up mostly in the city's postwar inner suburbs, where builders left more room on the lot. If your Toronto home has two separate single doors, or you're comparing installation and replacement quotes, this page covers what changes and what stays the same.

What Toronto's housing stock means for the job. Toronto's building stock splits sharply by era. In the old city core, the semis and rowhouses built before amalgamation, garages are usually a single detached structure off a rear lane, if they exist at all. The two-single-door setup this service is built for shows up almost entirely in the postwar bungalow belt of North York and Scarborough, built through the 1950s and 1960s, where an attached garage with two narrow doors and a centre post was standard. Because those garages are single-storey with nothing above, most Toronto conversions fall inside the full $16,000–$18,000 CAD band without a room-above adjustment.

We take on conversions across Toronto, including North York, Scarborough, East York, Don Mills, Willowdale and Agincourt.

Double garage door installation in Toronto

We install double garage doors in Toronto two ways: as the final step of every two-to-one conversion, and as standalone replacements where the wide opening already exists. They are different jobs with different price tags, and it pays to know which one you need before collecting quotes.

If your Toronto garage already has one opening sized for a double door, you need an installation or replacement: a non-structural job, no permit, typically a few thousand dollars. If you have two separate single doors with a post between them, widening that into one opening is structural work: an engineered beam, a building permit, and masonry reinstatement, which is the conversion this page describes. Typical replacement ranges are on the Ontario cost guide.

What a conversion costs in Toronto

$16,000 – $18,000

CAD, all-in · bump-out or detached garage · nothing load-bearing above the opening

The range covers the structural assessment and engineering, centre post removal, the engineered beam, exterior finishing, and a custom-width double door, in one contract. The municipal permit fee, typically a few hundred dollars, is extra. A room above the garage changes the beam design and is priced at the free assessment, never guessed at.

The permit: structural widening in Toronto is permitted through the City of Toronto (Toronto Building). We prepare the application with stamped engineering drawings, file it, and carry the inspections. The full breakdown of what moves the number is on the cost guide.

How the conversion runs

Every Toronto conversion follows the same fixed sequence, engineered around the load, not guessed at:

  1. Structural assessment
  2. Engineered beam design
  3. Building permit filing
  4. Temporary support and centre-post removal
  5. Beam and header installation
  6. Framing
  7. Exterior finishing
  8. Custom-width door and opener install

The full 8-step process, with the beam engineering and the permit table, is on the two garage doors into one conversion guide.

Representative profile — Postwar bungalow, attached garage, nothing above the opening

  • Structural assessment and stamped beam design
  • Municipal building permit and inspections
  • Centre post removal with temporary support in place
  • LVL beam sized for the roof load across the combined opening
  • Brick and one-piece lintel reinstatement to match the facade
  • 16'8" or wider custom-width double door with opener upgrade

Toronto questions, answered plainly

Does my Toronto home qualify for the $16,000–$18,000 CAD price?

If your garage is a single-storey postwar bungalow, common across North York and Scarborough, with nothing load-bearing above the opening, yes. Older Toronto homes with a rear-lane detached garage are assessed individually, since the structure and access are different from an attached bump-out.

Who issues the building permit for a garage conversion in Toronto?

Toronto Building, the City of Toronto's permit division, reviews and issues the permit for widening a garage opening. We prepare the stamped engineering drawings and file the application; Ontario's Building Code requires a decision within 10 business days of a complete submission.

I only need a new double garage door installed in Toronto, not a conversion — can you help?

Yes. If your opening is already sized for a double door, that's a standard installation or replacement, not structural work, and it doesn't need a permit. We handle both jobs; the two-to-one conversion is only needed when you're starting from two separate single doors.

Are two-single-door garages common in Toronto?

Less common than in the surrounding GTA cities. Toronto's older core mostly has detached rear-lane garages or no garage at all, so the two-single-door layout is concentrated in specific postwar pockets of North York and Scarborough rather than spread evenly across the city.

Does a laneway or detached garage in Toronto qualify for conversion?

It depends on the structure. A detached garage with two single doors and nothing above it can often be converted the same way an attached bump-out is; we confirm the specifics, including lane access for materials, at the free assessment.
