Hello Casey,
If you receive a suspension in Quebec it will be recognized by Ontario. You would need to speak to the MTO regarding the demerit point issue.

Unfortunately, we do not handle tickets in any other Province of Canada except Ontario.


Subject Other (any/all other driving charges)
Name Casey

Inquiry I live in Ontario and I have an Ontario G Driver’s licence. While visiting
Quebec, I received a ticket for not wearing a seat belt while operating a
motor vehicle. If I do nothing, I will be convicted and charged a fine of
$200, three demerit points, and receive a licence suspension until the fine
and any additional fees are paid. Once I am suspended in Quebec, will
Ontario also suspend my driver’s licence? And will I also receive the
three demerit points in Ontario?
