I’m not an expert in the Canadian market, but here’s what I got from some of my sources. The National Building Code of Canada (NBC)
only references CCMC-approved foam so you need CCMC approved foam to legally use it in a building. You need to purchase foam from a
manufacturer who has a CCMC approved foam in Canada. They will lead you through the process of getting certified to install their
foam. All buildings that fall under the NBC need to have products that are CCMC approved. Try going to the CNRC website to look up spray foam products that are approved then contact those
manufacturers. This may also be a great question for the SprayFoam.com forum.
