Why don't you try to google up name change process in Alberta? That is what anyone else will do for you on this thread - might as well skip a step and do it directly. It shouldn't be a very elongated process to change name as long as you have your birth certificate, divorce certificate etc.
Hi, I am on a PR with my Husband, where is a Primary applicant in the Ontario region. I would like to take a Divorce, will it impact my PR? Will it be vise to register for Divorce here or in India?
