Bonjour pe37,
Evansb has given good advice. You will find more choice for aircraft rental in Quebec, and eastern Ontario, than it appears.
ATAC in Canada:
ATAC - Operators
will list most of the flying schools/clubs who would rent GA aircraft.
This list:
AIRCRAFT OPERATOR - FIXED WING | Canadian Aviation Guide - A-List
Should also be useful.
You are welcomed to PM me, if you need further help...
