Hi I am a male in a same sex relatonship and I have been reading about so many different things about "misrepresentation" I am getting nervous. When my partner and finally I decide to get married, in Canada of course where it is legal, do I have to state that to the border on the day I cross into Canada to do so? Or can I just get married at any time during a visit in Canada.. I don't want to mess anything up.
Bottom line: you can, indeed, decide to marry and get married while just "visiting" Canada. And that should, generally, not cause any problems with a PR app down the road.
But yeah, that can be an issue. In large part it depends on what they ask. It may also depend on whether you are in their system, and if so to what extent, if any, they have concerns about you.
If you visit Canada regularly, you should, by now, know the drill, know what sort of questions they will ask. They rarely ask "do you intend to marry in Canada during this trip?"
So are they asking you questions which would require you to tell them you plan to marry?
For me the level of inquiry varied and sometimes they pressed me about my relationship with a Canadian, about my specific itinerary, but I was already in the system, already on their radar as someone with a significant other in Canada and spending a great deal of time in Canada. But even then I was rarely asked any question to which I would have had to say I was getting married on that trip.
Ironically, the last time I crossed the border before getting married in Canada and applying for PR, I volunteered that my significant other and I had no intentions of marrying and I had no intentions of residing in Canada . . . then, a few weeks later my partner and I decided to in fact change the course of our lives, get married, and settle down on this side of the border. Of course in making the application for PR we clearly explained how this was indeed a change of mind. I do not know to what extent they made a record of what I said at the border (about no intent to marry) but in any event it did not harm us in any way.
That said, I would not lie about this. Deception can indeed come back to haunt you.
