The code in Canada specifically states that all EV chargers require a GFCI breaker installed.Yes it makes little sense and creates problems. (Most EVSE won't work with this setup so you have to hardwire them). However, like I said, the code is usually a response to a specific problem. In this case it's unlikely to have involved an EVSE or any other device which had a GFCI. But since you can plug any number of devices into an outlet, it's hard to make an exception. Though in fact this does occur with the requirement of a label stating that only X device can use the outlet, they just went ahead and required a GFCI. This no doubt solved the problem they were looking at but has created problems for EV charging.
The reason 40A breakers would be better than 50A is that they match the EVSE. While the saying is "the breaker protects the wire", it's also true that it protects the appliance.
I just noticed you are in Canada. Would the requirement for the 14-50 outlet even apply to you? As noted it's the rule in many but not all US jurisdictions.
" All single phase receptacles installed for the connection of electric vehicle charging that are rated 150 Volts to ground or less and 50 Amps or less shall have a GFCI".
