Of course nobody talks about the actual emissions required to build an electric car versus an ICE car, which is nearly 2x the rate of the former. To make-up for that initial 'footprint' takes quite a bit of fossil fuel burning by the driver.
If Canada's own forecast data is any measure of veracity, one only needs to point to the horrendous execution of our 500,000 EV vehicle goal by the end of 2018 (the one that we barely managed to clip 1/5th of). You might as well say cars will run on happy thoughts by 2040 given the atrocious forecasting of late.
Here's the thing. The entirety of the developed world save for several nations with hydro power and the entirety of the developing world relies heavily on fossil fuels for electric power generation. The likelihood of that reliance diminishing substantially in our lifetimes is low when viewing the future through a pragmatic and realistic lense. Even uber-green Germany with its forests of wind farms depends on fossil fuels to power over 50% of its grid, with renewables accounting for about a quarter and where they're likely to remain as their unreliability and costs are starting to reveal themselves.
Furthermore, what does ICE Average consist of? Massive mine vehicles? Big-rigs? Smart cars?
