Hi Sis,
Well, it could be a good idea that you can use different departure immigration booth. There are two (except special for worker) departure immigration booths. Just you will feel that you are going Canada in different time.
As I said that you will not face any problem because you have individual visa in your passport. Immigration officer will check your passport and visa has stamp or not. Immigration officer will match with passport name, visa and photograph. Passport should carry with right person. So there shouldn't be any problem.
Just let me know that is there your spouse name is different written in your passport or there is no name in your passport bio-data page (just curious). As we know that Bangladesh immigration doesn't require to carry marriage certificate during their travel.
So again I say "
Don't worry" and feel proud that you have ability to obtain the Canada PR visa which already have. Don't be angry if immigration officer ask you so much irrelative questions because most of immigration officer works there more than 16~20 hours per day. As a human being this is too much reason they are very slow and IT system doesn't work as our country started work on DIGITall.
