-Revocation or renunciation should not affect a separate PR application - although as noted that may still be difficult.Excellent remark. Sure inability to travel is a problem to see family abroad. This option is a bet on chance. If i enter and got revocation order, i prefer to go back and not do an appeal and i wonder if revocation order is a bad point for future application.
-It is of course a bit of a bet. Note, it's not that travel is not allowed (of course), but that every time you return while out of compliance there is a chance of being reported.
-The risk will go down somewhat if you're clearly living in Canada and the closer you are to the 730 days to be in compliance*, but risky (esp if warned at border).
*By this, I mean that you always have the right to attempt to make an H&C case, and the officers at border are aware (and they don't like spending time writing reports that will be overturned later). So, for example, someone who has 729 days and goes on a short trip abroad - that's less risky. Someone who has far less days in Canada and then leaves for six months or a year - very different.
But in the end: only way to avoid the risk entirely is to be in compliance.
