You cannot apply to go to Canada yourself directly. Unfortunately the program doesn't work that way.
There are really two main ways to come to Canada. Each requires you to find a sponsor. The first is to be sponsored through a Group of Five sponsorship. This requires you to know someone in Canada (family member of close friend) who is able to find four other people willing to support your sponsorship. The second is to find an organization that is a Sponsorship Agreeement Holder (SAH) and is willing to sponsor you. Unfortunately most SAH organizations are no longer accepting sponsorships.
Otherwise you have to wait for UNHCR to resettle you. They will chose where you are resettled, you don't get to pick. Most people are resettled in the country where they already are.
