Door Replacement Costs Across Canada — 2026
Standard patio door replacement costs $2,200 to $2,400 across major Canadian markets, while entry doors with sidelights range from $3,900 to $4,000 depending on installation complexity. These figures reflect supply and installation for pre-hung units from national retailers, though regional labour rates and regulatory requirements create significant cost variations.
The data reveals distinct patterns across door replacement categories, with garage doors showing the widest cost spread from basic installations to complex automated systems.

| Interior door replacement | $700 | $700 | ON | Single door installed |
| Garage Doors | ||||
| Standard steel insulated garage door | $1,500 | $4,000 | BC | Single-car, Vancouver area |
| Installation Labour | ||||
| Full frame replacement | $1,500 | $3,000 | BC | Energy efficiency upgrades |

| Retrofit installation (healthy frame) | $800 | $1,500 | BC | New door in existing frame |
British Columbia shows consistently higher labour rates, with installation running $80 to $120 per hour in urban markets like Vancouver and Burnaby. This reflects the province's WorkSafeBC requirements and seismic building standards under the BC Building Code, which often require additional structural considerations for door frame installations.
Ontario pricing clusters around standardized retail offerings, particularly the $2,200 baseline for standard patio doors and $3,900 for entry doors with sidelights. The province's mature construction market and WSIB coverage requirements create relatively predictable pricing, though Toronto-area installations command premiums for complex projects like multi-panel patio doors reaching $5,000.
Provincial Cost Drivers and Regulatory Impact
Climate factors significantly influence door replacement costs across provinces. British Columbia's coastal moisture and seismic requirements under Technical Safety BC standards drive up installation complexity, particularly for full frame replacements at $1,500 to $3,000 when addressing rot or upgrading for energy efficiency. The province's rainscreen wall assembly requirements often necessitate additional waterproofing and structural work.
Ontario's freeze-thaw cycles and deep frost lines create different challenges. The Ontario Building Code's thermal performance requirements influence material selection, while ESA electrical inspection requirements for automated garage door systems add regulatory overhead. The data shows garage door motor installations ranging from $150 to $300 in labour costs, reflecting standardized electrical work requirements.
Alberta's extreme cold climate drives demand for high-performance installations, though limited data shows structural modifications for door openings at $2,000 to $6,000. The province's Safety Codes Council oversight and expansive clay soil conditions often require additional foundation considerations for major door frame modifications.
New Brunswick's harsh maritime climate creates unique challenges with deep frost penetration and coastal salt air corrosion. The province's Technical Safety Authority oversight and older housing stock mean door replacements often involve structural upgrades to meet current building codes.
Labour market differences explain much of the provincial variation. British Columbia's tight construction labour market pushes hourly rates higher, while Ontario's larger contractor base creates more competitive pricing for standard installations. Workers' compensation requirements vary by province, with WorkSafeBC, WSIB, WCB Alberta, and WorkSafeNB each imposing different premium structures that contractors pass through to project costs.
Permit and inspection requirements also vary significantly. Ontario's HCRA registration requirements for residential builders add compliance costs, while British Columbia's Homeowner Protection Act licensing creates quality assurance overhead. These regulatory frameworks influence final project costs even when the core installation work remains similar.
For homeowners planning door replacements, the data suggests budgeting $2,500 to $4,500 for standard patio door projects and $4,000 to $5,000 for entry doors with architectural features. Interior door replacements remain more affordable at $400 to $900 per door, while garage door projects span the widest range depending on automation and material choices.
