Thanks so much for your information. We dont intend to travel anytime sooner unless we have something in writing from any of the government bodies. so far, we just have an email for our inquiry from the Canadian Embassy in our home country confirming that we don't need a written authorization for my spouse to travel as I am a PR holder. But, i doubt that would be enough to persuade anyone in the boarder.
Also, just out of curiosity, lets say she does manage to get into an airplane and land in Canada, what happens if she cannot go back to the origin of travel or the home country as both have restricted travel.
