No one here knows who you are, and you haven't mentioned any dates, so I'm not sure what you're trying to protect by not sharing the route.
But you hot the question absolutely correct!
And it doesn really matter (according to my understanding) if it is your example:
FRA-YUL-YVR-MEX => FRA-YYZ-YVR-MEX
or for example
CDG-YUL-YOW // YOW-CUN => CDG-YYZ-YOW // YOW-CUN
So: Departure out of Europe (doesnt matter if CDG, FRA, LHR etc.) to Toronto instead of Montreal (or the other way round), further routing stays the same.
Is that possible (traveling in Business)?
Counter? App? Online? Telephone?
