Glazing and Window Treatments Licensing in Ontario

Glazing is a voluntary (non-compulsory) trade in Ontario. The Glazier and Metal Mechanic apprenticeship is available through Skilled Trades Ontario, requiring 8,000 hours (approximately 4.5 years) of training. Red Seal endorsement is available. No licence is legally required for window installation, but building permits may be required when changing window sizes or adding new openings. Replacement windows must meet Ontario Building Code energy efficiency standards. Window treatment installation (blinds, shutters) does not require any licensing.

Ask if they hold a Certificate of Qualification as a Glazier. Verify they understand Ontario Building Code energy standards.

(1) Does not discuss energy efficiency ratings or Energy Star certification (2) Skips proper insulation (spray foam or backer rod and caulk) around the window frame (3) No exterior flashing or weatherproofing included in the quote (4) Quotes without measuring - every window opening is different

(1) Are the windows Energy Star certified for Climate Zone 3 (Ontario)? (2) Will you install proper insulation and flashing around the frame? (3) Is this a retrofit (insert) or full-frame replacement, and which is recommended? (4) Am I eligible for government energy rebates, and will you help with the paperwork? (5) What warranty comes with the windows and the installation?

While not legally required, it is strongly recommended that glazing and window treatments carry liability insurance. Ask for proof of coverage before hiring.

The Red Seal endorsement is a nationally recognized certification that allows tradespeople to work across all Canadian provinces and territories without additional testing. A Red Seal-endorsed tradesperson has met a standardized level of competency.

Typical rates for glazing and window treatments in Ontario range from $50-$100/hour. Window type (casement, double-hung, slider, picture), frame material (vinyl, wood, aluminum, fibreglass), glazing type (double vs. triple pane), window size, Energy Star rating, installation complexity (retrofit vs. full-frame replacement), number of windows, and location. Full-frame replacement costs 30-50% more than retrofit (insert) installation. For window treatments, cost depends on material, style, motorization, and custom vs. standard sizing. Government rebates through the Canada Greener Homes program can offset up to $5,000 for energy-efficient window upgrades.
