Can I travel to Canada while doing AOS?

You will not be admitted. You will be paroled into the U.S. I just came from Canada on AP, there were no issues going there or back. The Canadian official at the border will want to see your combo card to prove you have a way of reentering the U.S.A and that you're in legal status / waiting for your GC. Some Canadian border officers are not familiar with the relatively new combo card - they are used to seeing the I-512L form on paper - so if they are baffled by the document you're showing, you'll need to explain it serves the same purpose.

Warning: the re-entry bar triggers if you leave the country after accruing at least 180 days of unlawful presence. The timer stops as you send off your AOS and NOA1 receipt is issued, since you enter what is officially called a period of authorized stay. Any time between the expiration date on your I-94 and your AOS NOA1 date counts as unlawful presence and tolls towards the bar. Make sure you do not leave the country if you're facing the 3 or 10 year bar.

Cheers!

OP would still need a visa to enter Canada being a Philippine citizen. While not required for someone from Poland with the BIO passport, a visa is required from OP to enter Canada.

OP...as everyone else has said, wait until you have your GC in hand before you leave the US for ANYWHERE.

Well of course. But OP was asking about being readmitted into the U.S., not about being admitted to Canada, and that's what my post is about. I assumed, maybe wrongly, that OP is already in possession of valid travel documents to cross the Canadian border.
