It is fun !!!
Things to ponder:
Flight plan to cross the border,
Check the latest CFS (Canada Flight Supplement) for procedures for the Montreal area (available in Foreflight)
Have the Montreal VTA chart on hand, it's a VFR Terminal Area chart with more details and the VFR routes (available in Foreflight)
Ensure you have a VFR transponder code before calling ATC
At times, because of lack of staff or other, some restrictions to VFR flight in the Montreal terminal can exist...
Here's a couple of screen shots of the CFS and the VTA from Foreflight.
