When you ask a yes or no question and get "it's complicated" the real answer is simply no. I have found this to be true at almost all times. The only time it isn't true is when the positive answer is no, such as "did you do this bad thing"? In those cases the formula still works the answer is always in reality, yes.

EVs should be charging at night, and they should be charging off-peak rates to do so. Some cheaper cars like the Nissan Leaf don't have enough capacity to make it through the day without charging.
This is a temporary problem. If a car has 200 miles of range (teslas have at leaat 230) and its only used for 60 miles per day (even in -40F conditions), nighttime charging is still on the table. Off-peak power can be as much as 1/3 to 1/4 of peak, so there is incentive to do so, particularly for transportation.
The article discusses grid limitations, not generation limitations, though it may be a factor at the moment and they are bringing online a new plant to meet demand (according to the article).
Alberta is a very cold continental place, and consequently, the majority of its population is concentrated in Calgary (much like other metro-areas like Toronto, St. Louis, Kansas City and Minneapolis.) This can be a challange for the electrical grid to meet peak demand. There simply isn't much real-estate to put new subatations. Some urban substation locations have original buildings from over 100 years ago with asbestos and knob & tube wiring throughout. The cost, and impact on "five nines" uptime of running new, higher voltage and lower-sag wires in a city makes upgrading often a pipedream.
So yes, places like Calgary where the population isn't being driven out of dense urban areas by forced integration from hostile nations and psyop-driven race-baiting because the government isn't insane like most western governments, it can be a challange to meet demand for electricity from a more economical means of transportation.
