Are CertainTeed shingles made in Canada?

Yes, some CertainTeed shingles are made in Canada, though not all, as CertainTeed operates both US and Canadian manufacturing plants. CertainTeed Corporation, owned by Saint-Gobain, has roofing shingle manufacturing in both countries. In Canada, CertainTeed and its sister brand BP Building Products, which is also owned by Saint-Gobain, manufacture shingles at plants in LaSalle, Quebec and other locations. The LaSalle, Quebec plant is a major facility that produces asphalt shingles for the Canadian market including CertainTeed Landmark series and BP lines like Mystique, Manoir, and Eclipse, with bilingual English and French packaging and CSA A123.5 certification required by Canadian building codes. Additionally, CertainTeed has distribution and some production through its Canadian subsidiary Kaycan. However, many CertainTeed shingles sold in Canada are also imported from US plants such as Oxford, North Carolina and Shreveport, Louisiana, because CertainTeed operates an integrated North American supply chain. So when you buy CertainTeed shingles in Canada, they may be made in Canada or made in the USA depending on color, product line, and regional inventory. If you specifically want Canadian-made CertainTeed or BP shingles to support Canadian manufacturing, ask your supplier for BP shingles made in LaSalle, Quebec, which are definitely Canadian-made, or check the packaging for Made in Canada labeling and CSA marking. IKO and BP are the most consistently Canadian-made brands.
