I will answer your question. Yes you have to mention Married in form. You have to submit marriage certificate in bls in Toronto or Vancouver or wherever you are. Doesn’t matter your marriage is registered in India you still have to answer married. On the other hand, if you said your parents doesn’t know you are married here, you can select single because when they do verification in india, they ask your parents they is your child married in Canada. Also PCC doesn’t show your status. It just shows that there is no record regarding your in india. That’s all it says on pcc.
