Canadian Building Code Requirements for Structural Plywood Panels

Product Certification
Building codes applicable in Canadian jurisdictions specify the use of products manufactured to specific standards. Wood-based panels (plywood and OSB) used for subfloors, roof and wall sheathing in Housing and Small Buildings (Part 9 construction) must conform to CSA standards.

Panel Thickness
For products manufactured to prescriptive Canadian plywood standards (CSA O121 Douglas Fir Plywood, CSA O151 Canadian Softwood Plywood, or CSA O153 Poplar Plywood), the applicable building code specifies a minimum required thickness for floor, roof and wall sheathing applications. There is no allowance for the substitution of thinner (“scant” thickness) panels within prescriptive CSA standards; ie:

- 11/32” / 8.7 mm plywood can not be substituted for applications specifying 9.5 mm (e.g. use as roof sheathing with supported edges @ 24” o.c.)

- 15/32” / 11.9 mm can not be substituted for applications specifying 12.5 mm
(e.g. use as roof sheathing with unsupported edges @ 24” o.c.)

- 19/32” / 15.1 mm can not be substituted for applications specifying 15.5 mm
(e.g. use as subflooring @ 16” o.c.)

Note: This information does not apply to products manufactured and rated to performance standards such as CSA 0325 Construction Sheathing. These types of products are certified to provide adequate performance as
construction sheathing and may be of non-standard thicknesses, potentially including thinner (scant) thicknesses.

Panel Marking
CSA plywood standards specify various marking requirements, including additional requirements for "non-standard" thicknesses.

Plywood certified with the CANPLY mark provides third party assurance that products are manufactured to conform to all applicable codes and standards.

Plywood with this mark is exclusively manufactured by members of the CertiWood Technical Centre, listed below:
