What charging speed are you getting on your Level 2 charger?

CEC part 1 2018 24th edition (and this rule has NOT changed since previous editions)
Rule 8-102, Sub-rule (1) The voltage drop in an installation shall be based on the connected load of the feeder or branch circuit if known; otherwise it shall be based on 80% of the rating of the overload or overcurrent device protecting the branch circuit or feeder, and not exceed
(a) 3% in a feeder or branch circuit; and
(b) 5% from the supply side of the consumers service (or equivalent) to the point of utilization.

the CEC rule is about the voltage drop inside an installation, not what the power company is going to give you.

the power company gives you power at the "consumer service" point. the 5% drop in the code is "from the supply side of the consumers service (or equivalent) to the point of utilization." meaning from the entrance side of your panel to the power outlet.

this simply means you have to size your wires large enough to not have a voltage drop larger than 5%.

it doesn't say anything about the actual voltage you get at the consumer service connection point.

the applicable standard for the utility side is ANSI C84.1 or CSA CAN3-C235-83

here are the values for ontario: normal operating condition 110/220V to 125/250V. extreme conditions 106/212V to 127/254V

Those voltage differentials seem pretty extreme. I even get the better part of 108 V from a dodgy 14 gauge 100 + ft run to my outhouse.

the numbers quoted are the min and max guaranteed at your point of connection to the utility side for 95% of the time.
they guarantee that 95% of the values will be 106/212 V to 127/254 and 99.9 % of the values will be -15 % to + 10 % or 102/204 V to 132/264 V

this is for canada according to standard CSA CAN3-C235-83. For the US it's ANSI C84.1

I'm getting 7.0-7.1 kw on the local charging network in Quebec.

7.3 Kw on a Morec 32 amp evse plugged into NEMA 14-50 (50 amp) outlet.
