Electricity and heat is indeed the largest sector by emissions in Canada (about a quarter) [1]. Though depends on where you are. In BC all electricity is hydropower, and if you have electric heating, your emissions are close to zero.

Transport is also about a quarter. So Canada can indeed cut emissions in half with present day tech by fixing these two sectors. Still a long way to go.

Also note that Estonia is at 7.3t, Finland 5.6t, Sweden 3.5t (Sweden was 8.6t in 1980). So climate is not really an excuse. It is just politics.
