I did my Masters degree program in the United Kingdom in 2008. While i was studying in the U.K, i applied for a visitation visa to Canada and was issued the Visa. I booked the ticket, my hotel and every other thing but was prevented entry into Canada (Toronto), this was in 2008. On returning to the UK, i wrote the Canadian Immigration and expressed my dissatisfaction about the incidence and i got an apologetic response and was told that that does not stop me from applying in the future to Canada. With this experience, can i still apply for the Canadian Express Skill Program? Please advise.
