Real wood still wins on looks. These guides cover what it costs to keep it that way in an Ontario climate.

How we check our guides

  • Written by the DecksToronto editorial team. Guides are researched in-house and reviewed against the deck material and installation experience behind the site, not rewritten from other blogs.
  • Checked against primary sources. Building requirements come from the Ontario Building Code and the relevant municipality; product claims come from the manufacturer's current product, warranty, and care documents.
  • Dated, not evergreen-by-assumption. Each guide shows the date its facts were last verified. Prices and code thresholds are shown with that date attached, or left out.
  • Separate from the shop. DecksToronto is educational. Where a product is genuinely available in Ontario we link to it, with current prices supplied by Composite Deck Shop. Confirm the selected variant and delivery with the store.
  • Corrections are shown, not deleted. If guidance changes, we update the affected explanation and link to the source so you can check the details.
