I am building my own home and the certified electrical contractor has placed the breaker panel in the double car garage, which is not insulated.

This is the first time I have across this and was wondering what the pros and cons for this location would be.

Your comments would be greatly appreciated.

Building code require Insulation of walls of the house where they are facing outside. However, it is not requirment of electrical code.

In Alberta the current (2019) Building Code requires that exterior walls and ceiling of attached garages be insulated whether or not the garage is heated. The Code also requires that the continuity of the wall insulation (and air barrier) not be reduced for electrical panels.

I would think it would be the same in Ontario - suggest you confirm with your local municipality.
