Canadian Grading Agencies


ALSC / CLSAB / CWC


NLGA




Mission (What They Do) ◦ Ensure market access, to maintain and expand

markets for Canadian wood products in North America

Primary Role ◦ Address building code changes that threaten to

restrict or eliminate wood construction

◦ Ensure code changes result in net win for wood construction in North America

◦ Make it as easy as possible to specify and use wood (Knowledge Transfer and Education)


ALSC / CLSAB / CWC


NLGA




The NLGA was incorporated in 1971.

Responsible for writing, interpreting and maintaining Canadian lumber grading rules and standards.

The rules are approved and enforced by CLSAB and ALSC – enables acceptance under Canadian and US building codes.

Canadian grading rules must meet the NGR.

The membership of NLGA consists of all the lumber manufacturers' associations and independent grading agencies in Canada.
