Hello . I have a question Im moving to Canada next January I have a work visa I get a six months work permit, but I dont know If I have to buy one way plane ticket or two ways plane ticket. I mean is it compulsory to buy two way plane tickets ??

THAnK YOU IN ADVANCE

The choice of plane ticket is not a factor in the work permit application process. It can effect visitor admissibility; if your case has already been approved, it should be less critical.
