I assume you have 19x7.5" wheels based on below link:
https://www.wheel-size.com/size/merc...50-4matic--221

245/50r19 set has 1.37% difference in tire circumference which is under 3% recommended max:

However 7.5" rim max tire width is 235, so 245 is not recommended. You might need 8" rims for 245 width.

235/55r19 set has 3.17% difference is over 3% recommended max:

Just as an FYI, Continental Tire indicates that the acceptable rim width for 245/50R19 is 7.0” to 8.5.” If Canadian safety regulations say otherwise, obviously that would supersede Continental’s opinion.
