As mentioned, I would plan for the question but not expect it. I think it is unlikely to be an issue for you, as a citizen there is no problem going for extended period outside of the country, the only possible issue is the intent to relocate and the fact that you will still be working for the Canadian company should mostly take care of the question along with an explanation that you were able to temporarily work remotely and therefore, to reunite with your spouse, went there while the PR was being processed. A letter from your employer at that time saying that you working from another country is temporary, would likely be plenty of proof if needed (no need to get it now, just if you are asked to show intent).
One thing to consider though, and I feel much more likely to impact you, are the tax and immigration implication associated with work done remotely from a different country. This is very country specific and some embraced it with covid, creating new visas specifically for that. Talk to your employer (CPP, EI implications), talk to a tax specialist/do your research about the specific rules of that country.
