Plywood price in Canada: what a 1/2 inch sheet costs at Quebec retailers

The table is the price of one standard 1/2 inch 4x8 spruce plywood sheet at each Quebec retailer, seen October 13, 2026. Canac is cheapest at $37.48 and Matério the priciest at $40.89, a gap of $3.41 per sheet (9.1 percent).

Plywood is a tightly priced product: 5 of the 9 stores list it at $37.48. The gap that does exist comes from the stores at either end of the table, and it adds up on a full order.

A 4x8 sheet covers 32 square feet. At the cheapest store we track that is $1.17 per square foot, and at the priciest $1.28. Use the per square foot figure when you compare a different panel size or thickness, because stores also sell 4x10 sheets, half sheets and different thicknesses.

Both are structural panels, and building codes accept either for sheathing in many uses. OSB is pressed from strands of wood and plywood is glued from thin sheets. OSB is usually the cheaper panel; plywood tends to handle getting wet better, because OSB edges swell if they sit in the rain.

At the median price we tracked, a 1/2 inch plywood sheet costs about 2.5 times a 7/16 inch OSB sheet. Those are different thicknesses, so read it as a rough guide: the table below puts both next to a thicker tongue-and-groove OSB subfloor panel.

What thickness and grade you need for a subfloor, a wall or a roof is set by your building code and the span of your framing. Confirm it before you buy.

The shelf prices on this page are what Quebec retailers charge. If you build somewhere else, the best official yardstick we have is Statistics Canada's building construction price index, which follows what builders pay for wood, plastics and composites in a single-detached house in each province.

Quebec, where our shelf prices come from, reads 118.8, up 5.0% on a year earlier. That is the highest of the 9 provinces Statistics Canada tracks, and Ontario is lowest at 97.4 in the second quarter of 2026. These are cost indexes set to 100 in a base period: they say how fast lumber and panel costs have moved in each province, not what a single item sells for at your local store. We will publish real shelf prices for your province as it goes live.
