I'm not aware of any Jasper specific groups anywhere. Still for those in the Greater Toronto (Ontario, Canada) Area (GTA) there are a few groups that seem to welcome everyone that do overlap with Jasper (sort of):
Raspberry Pi Meetup -
http://raspberrypi.meetup.com/ - Meet-ups in several cities, the GTA group meets second Thursday of each month
Unix Unanimous -
http://www.unixunanimous.org/ - Second Wednesday of each month - Bring your Unix or Unix-ish related question(s) and we will try to find answers for you. Note: I am fond of this group as I act as moderator for the group :-) ...
Drink Coffee and Write Code -
http://www.meetup.com/Coffee-Code/ - Tuesday, Thursday and Sundays - Bring your laptop and be ready to write software with others...
The Kitchener Waterloo Linux User Group -
http://kwlug.org/ - First non-holiday Monday of the month - Bit of a hike out of Toronto, but they do seem to welcome everyone.
All the best.
