You should be fine with 回鄉證, I don't know if HK passport is needed to be used in conjunction with it tho.

On another note, unless my life is depended on it, I'd try to avoid showing 回鄉證 and Canadian Passport at the same time tho.

Doesn't matter where you enter from. Imagine the scenario where someone only with HK citizenship went to Canada for vacation and then need to enter Beijing for business right after. He/she would have to use his/her HK Passport + 回鄉証. So it's okay to enter with 回鄉証 only from Vanc -> Beijing.

Remeber to just use one or the other. Avoid to show both. If you enter w/ 回鄉証 you are entering as a HK Citizen, and if you enter with Canadian Passport you are entering as a Canadian National.

That said, if your life depends on it, I guess at the very minimum the Canadian Embassy will treat you as a Canadian National regardless of your method of entry.

Yes, you are not 'supposed' to have both 回乡证" and Canadian Passport at the same time. Basically, the Chinese gov't does not allow a Chinese National or a HK Citizen to possess two ways to enter China. If they find out, they might confiscate your 回乡证 (Chinese Passport and Citizenship potentially for a Chinese National).
