It's an emissions requirement, not "who made your cats, no matter how well they perform". If you can pass an emissions test, that's all that counts unless Alberta has a specific law that you must use oem parts when replacement is required. I somehow doubt there is a law stipulating that. No emissions tests here, thank God.
