Pending immigration petitions have no effect on other entries provided (and this is the key point) you have bona-fide non-immigrant intent when you enter. If you enter as P-2 with an intent to leave then it's not a problem. The question is whether your visa number will come up when you're in the US or Canada, which is why I would recommend using consular processing given the limited validity of P-2 entries, because you might find yourself stuck in Canada at the time. You can't then enter as a B-2 visitor and apply for adjustment of status because you would be lying about your intention when you enter.
As long as you've got a valid Canadian address it shouldn't be an issue, and to get P-2 in the first place you have to have residential ties of some sort to Canada.
Whether or not you get turned down for EB-1 has no real bearing on P-2, we've had many discussions on here about at which point USCIS at the border becomes aware of your petition, but I would guess they're less likely to become aware of a consular filing than an in-country filing, which is another reason to do it that way.
Bear in mind EB-1 is tough to get and the way those applications are processed seems to follow no logical path, imo. I knew one guy from the Bahamas who was widely considered an expert in his medical field and had written books, etc. and he got turned down. On the other hand I knew a guy from New Zealand who was some world champion at water skiing and he was approved for EB-1.
I guess reading up on qualifications to do with psychology is more tedious than looking at the cover of some water skiing magazine, that was the only way I could figure it.
