That's very bad news... Anyone here in Canada that had run into this problem with city/utility inspectors asking for CSA certificates?
No not at all. I'm wondering how you wound up in that scenario. Even when getting an electrical permit the install is the only thing my province is concerned with. Now if you are setting up a facility using MW as opposed to KW there may be more questions.
Best bit of advice I can give you is just let them know what you need supply wise, don't over divulge what you are running. Hope you got the permit.
