Thank you so much for your reply, wsongco! I also posted this question to another forum and was advised to go ahead with my plans since this wouldn't affect my application.
Is this actually stated in the Canadian Immigration website somewhere? I have been scouring the site but couldn't find a particular statement regarding this query.
But you know if I were you I will not marry yet. If your goal is to be a permanent residence first, it is quicker to be one when you are single than when you are married. So why not wait for let say 3 more years? Anyways, it so easy to go home when you are PR already. This is just an advice.
