In British Columbia, for example, there are currently about 17,000 EVs on the road and BC Hydro is predicting there will be around 350,000 by 2030, Fish said.
“This is estimated to add an additional 1,050 gigawatt hours of electricity load per year and is something we’ve been planning for and will be able to supply,” Fish said. To put that in perspective, BC Hydro sold nearly 58,000 gigawatt hours of power in 2017.

So, only an additional 1.81% in additional electrical load for only a partial electrification of the total vehicles on the road today.
To put it in comparison, per ICBC's statistics, there's about 3.2 million vehicle insurance policies in effect in BC:

Statistics Canada says in 2018, there were 3.8 million vehicles registered on the road in BC:

So, roughly 350,000 EV's on the road in 2030 means that if the total number of vehicles on the road remains the same, just 9.2% of vehicles on the road are EV's. Total electrification would require the wholesale replacement of all 3.8 million vehicles on the road.
And the power requirement for that would be immense; even using the numbers presented in the Globe and Mail article you referenced, you are looking at an increase of power requirements in BC by about 11,500 gigawatt hours on the extremely optimistic side (ignoring other transportation methods, all small passenger electric vehicles, no increases in population size, power density, or vehicle numbers)... going to need at least 2 Site C dams to equal that amount of additional power generation capacity required.
This is not a trivial amount of power generation required to replace all of the road vehicles with EV's, unlike some claims.
