How can I, an American with disability services, move to Canada?

As stated above, I am unfortunately an American and wish to move to Canada (currently looking at British Columbia). I currently have disability services necessary for my well being, but given the current state of things the writing's on the wall and will likely not last too much longer.

I've been doing some research over the last few days and want to know how viable/possible it is for me to move up north.
