Ottawa gets the coldest sustained winter of any large city in the south, which changes what an attic upgrade is worth long before it changes the rebate.
Ottawa's stock runs from pre-war brick in the inner wards through the enormous 1950s and 1960s build-out of Nepean, Gloucester and the old townships, and into modern suburbs further out. The post-war belt is where the money is: shallow attics, often loose fill that has settled well below the joists, and party-wall row housing where the top plate is a standing air leak. Sustained cold also makes ice damming a yearly event rather than an occasional one, and ice damming is an insulation and ventilation failure before it is a roofing problem.
Ottawa work is booked by appointment and grouped, so the further ahead you ask the better the date. The rebate does not expire faster out here, but the diary fills the same way it does everywhere else as November approaches.
Typical lead time: By appointment, usually within two to three weeks. Nothing about the rebate changes with distance — the programme is province-wide — but the diary does, and autumn fills before anything else.
No energy assessment, one measure, and the tier set by the depth we measure before we start.
