This is another one of those confusing questions. I don't know why they can't make it clear. The question asks .. "physically reside".. it could mean office address or home as it talks about where were you really residing. For example, if your employer was in Ottawa, but you were working remotely and living in Toronto, you would say Toronto (my opinion). Alternatively, you could be employed by a Canadian Company, but on a project overseas so you would technically be residing out of Canada.
I listed the office address, but also listed that i was living at the home addresses in question 10 during that period (in parenthesis). That should cover both scenarios.
