CLA Grading & Inspection



For over 100 years!


The Canadian Lumbermen's Association (CLA) was founded in Ottawa in 1907 and became incorporated in 1931. The CLA was created "to promote the interests and conserve the rights of those engaged in lumbering or in the manufacture, sale or distribution of lumber" (1947). In 2009, the CLA merged with the Ontario Forest Industries Association. Today, the OFIA Home of CLA Grading and Inspection “provides vision and leadership to companies involved in the manufacture, sale and distribution of Canadian wood products” (Canadian Lumber Standards Accreditation Board, 2016).


The CLA operates a lumber quality control service. This service permits softwood producing mills to grade-mark lumber. It also has Canadian, American and UK standard accreditation and certification privileges. The CLA services further include developing quality business opportunities, providing valuable and practical grading services and running educational programs.
