Nature is healing (mild /s), not that there isn't high risk of pivot backfiring for CAN. Regardless people forget Canada under the British and post independence was fundamentally an anti-American project until WW1. Before that, it took multiple wars and (failed) US annexation effort before CAN/US realized jawjaw was better than warwar, really when Canada realized you can't be FOB for US adversaries, then British, and even that coexistence was under decadesof mutual suspicion. Of course the chance of PRC/CAN defense cooperation is nil, US will never allow that considering all the NORAD infra, but way things are going, even generic trade with PRC (something US already does - agriculture, energy, technology) is probably going to put another 51st state annexation attempt back on the menu.
