I found an electrician, on the Tesla recommended list, and used by two members of this forum who will install the Gen 3 Tesla wall connector for me. He said that ESA in Ontario has recently approved this (and even two months ago it was not possible). The electrician will set the wall connector to 32 AMP which I understand is fine for my Model 3 and works with my 100 AMP panel. The work is guaranteed for life as long as it is NOT TAMPERED WITH. So I am happy!
