Just wondering if it's ok to enter Canada with a one way ticket and book the return ticket while in Canada? I'm coming from the States where I work as a nanny and my home country is China and I just been approved for a TRV to visit family for a wedding after I finish work here before going back to China. Will there be any problems if I don't have one? I don't know if they will check to see but the reason why I want to book a flight in Canada because I feel it'll be less issues than booking while I'm still in the States but I know when I plan to leave and I stated it when I applied for the TRV.
