Do you deliver across Canada?

Yes - we ship plywood anywhere in Canada from our Ontario warehouse. Most products are in stock locally and ready to go out as soon as your quote is confirmed.

Can I pick up my order in person?

Yes. Pickup is available at our Canadian warehouse and at our US warehouse in Newark, NJ. Let us know during the quote process and we'll arrange a time.

Do you offer volume discounts?

Yes. We offer discounts on full packages (bundles) of plywood. The number of sheets per package varies by product, so please call us to confirm the pack size, or simply submit a quote request and we'll sort it out for you.

Do you price-match other suppliers?

Send us a quote request with what you're seeing elsewhere and we'll do our best to match or beat it, especially on larger orders. Our pricing is competitive on volume and on premium grades.

Can I get a sample before ordering?

For large or recurring orders we can arrange samples on request. Send us a note about your project and we'll work something out.

Can I see your products in person before ordering?

Yes - both our Canadian warehouse and our US warehouse in Newark, NJ can accommodate in-person visits. Contact us first to arrange a time so the right person is available to show you stock.

Which plywood is right for my project?

It depends on three things: where the project will live (indoor, outdoor, in contact with water or concrete), whether the surface will be visible or hidden, and what tools you're using to cut it. Each product page lists the application (Interior, Exterior, Laser Cutting, Formwork, etc.) and grade. If you're not sure, describe your project in a quote request - we'll recommend the right product.

What's the difference between Interior and Exterior plywood?

The glue. Interior plywood typically uses melamine-based glue - strong and stable in dry indoor conditions, but not waterproof. Exterior plywood uses phenolic glue (often labeled WBP - Water Boiled Proof), which holds up to moisture, weather, and outdoor exposure. If your project will see rain, humidity, or any contact with water, choose Exterior. Application is listed on every product page.

How do I know which thickness to choose?

Common rules of thumb for furniture and cabinet work: 1/8" and 1/4" for backing panels, drawer bottoms, model-making, and laser cutting; 1/2" for drawer sides and light shelving; 5/8" for lighter cabinet boxes; 3/4" for cabinet boxes, furniture, structural work, and heavy shelving. Formwork and structural plywood use different thickness logic based on load and span. If you're unsure, describe your project in your quote request - we'll suggest the right thickness.
