I am due to travel with my husband who is on a student visa to Toronto, he has received all his visa and ETA. We have in process an application for my work permit visa and a study permit for our son, however it is still in process. We have though, booked flights to travel at the end of the month (3 weeks time). If my work permit and my son's visa are still in process at the time we are due to travel, can we still travel on a one way ticket? We are British citizens travelling from the UK. Any suitable advise will be appreciated.
