Deck builders in Toronto.

Toronto, home to 2.9 million residents, is Canada's largest city and the country's most competitive deck building market. The city experiences over 100 freeze-thaw cycles per winter, making material selection critical. Toronto's building department requires permits for decks over 24" above grade or exceeding 100 sq ft when attached to the house — permit fees run $400–$500. With average deck installation costs of $25–$35 per sq ft for labour (among the highest in Canada), composite decking is the most popular choice for Toronto homeowners seeking low-maintenance outdoor living. The city's mature neighbourhoods in Leaside, The Beaches, and High Park feature some of the most impressive residential decks in the country.

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.
