Deck builders in Ottawa.

Ottawa, Canada's capital with over 1 million residents, sits at the confluence of the Ottawa, Rideau, and Gatineau rivers. The city's extreme temperature range — from -30°C in January to +35°C in July — tests every decking material to its limits. Ottawa's frost line sits at 1.5m (5 feet), requiring deeper footings than most Southern Ontario cities. The bilingual nature of the National Capital Region means contractors often serve both Ottawa and Gatineau across the river. Popular deck areas include the Glebe, Westboro, and Barrhaven suburbs where backyard entertaining drives strong demand for composite and cedar decking.

Ontario's 100+ annual freeze-thaw cycles test every decking material. Composite and PVC handle this stress better than wood, which tends to crack and splinter after a few winters.
