Deck projects offer excellent outdoor living value in Canadian summers but material choice dramatically affects longevity and maintenance. Pressure-treated wood is cheapest upfront ($15–25/sq ft installed) but requires annual staining. Composite decking ($30–55/sq ft) costs more but lasts 25–50 years with minimal maintenance. Plan for proper footings below the frost line — in most Canadian cities, that's 4–5 feet deep.
Material choice is the #1 cost driver: cedar ($25–40/sq ft), composite ($30–55/sq ft), or exotic hardwoods like Ipe ($50–80/sq ft). Railings add $50–120 per linear foot. Multi-level decks cost 50–75% more than single-level. Built-in features like benches, planters, and pergolas add $2,000–$10,000.
