Deck builders in Oshawa.

Oshawa, population 166,000, anchors Durham Region east of Toronto. The city's revitalized downtown and growing suburbs in Windfields and Kedron are driving deck construction demand. Oshawa's location inland from Lake Ontario means slightly colder winters than lakefront communities, with a frost line of 1.2m. Labour costs average $18–$25 per sq ft — 20–30% lower than central Toronto, making composite decking and other premium materials more accessible.

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.
