When to book in Montréal
Montréal gets about 4,028 heating degree-days a year and has a winter design temperature of −22.3°C, according to NRCan's HOT2000 climate data for Mctavish. That gives Montréal a long window, roughly late fall to early spring, when the inside-outside difference comfortably exceeds the 10°C an infrared scan needs.
What the camera finds in Montréal houses
Of Montréal's 221,340 houses (single-detached, semi-detached, row houses and duplexes), 48% were built before 1961 and 86% before 1991, according to the 2021 Census. Older houses are where the camera earns its keep: empty or settled wall cavities, gaps at the top of walls, and cold corners where framing bridges the insulation. Run it with the blower door test depressurizing the house and every leak shows up as a cold streak.
What it costs
Most EnerGuide advisors include an infrared scan with the evaluation, but it isn't required, so confirm when you book. In Quebec, EnerGuide evaluations are booked through the provincial Rénoclimat program: the pre-retrofit evaluation costs $150 plus taxes, reimbursed when you receive financial assistance under the program, and the first post-retrofit evaluation is free.

Thermal imaging inspection in Montréal: common questions
When is the best time for a thermal imaging inspection in Montréal?
Late fall through early spring, when it is at least 10°C colder outside than inside. Cold, overcast days with no direct sun on the walls give the clearest images.
Can a thermal camera see through walls?
No. It reads surface temperatures. Missing insulation or an air leak shows up because it changes the temperature of the wall or ceiling surface.
Who does thermal imaging in Montréal?
Most of the 3 NRCan-licensed organizations serving Montréal bring an infrared camera to an EnerGuide evaluation; confirm when you book.
