Ontarian here, and mostly the same. However, buns and rolls are both commonly used, as are chips and potato chips.

BC. If you said rolls I'd know what you mean but I'd call it a bun. All 4 seem pretty standard. I have an english grandpa so chips are sometimes fries but I think even he calls potato chips/crisps, chips.
