Just having proof you changed religions won't get a refugee claim approved. You need a lot more than that. Plus, it sounds like you're planning to change religions just so that you can claim refugee status. If you do that, expect to be refused, forced to leave Canada and then banned from Canada.
It doesn't seem like you have been approved for a travel visa. Many people have their visa application refused so I would wait and see if Ican even get a trv. Doesn't sound like have any of the proof needed for an asylum claim at this time.
