Hello,
Is it possible to add Canadian North to the ground handler options? They do have their own equipment and personnel handler their flights in all their stations they service.
https://en.wikipedia.org/wiki/Canadian_NorthAddtionally, Executive Aviation is a smaller handler but are vast across many smaller operations in Canada.
https://www.executiveaviation.ca/Thirdly, MaintAir Aviation Services, another small operation, based in Thunder Bay, Ontario with a few stations across Ontario and the East of Canada.
