Our family are all PRs, and have been physically living in Canada since 2016. My wife had to go to India couple of weeks back due to a family emergency, and is scheduled to land back in Toronto Pearson on Sunday morning. She is flying direct on Air Canada from Mumbai.
Canada just announced it is closing its borders to visitors, and only citizens and PRs will be permitted to enter. As PRs we appear to be fine for now, but Sunday feels like a long way off. Very concerned with the pace at which travel restrictions are widening.

Unfortunately there is a chance her flight may get cancelled. If would likely have to make sense for the airline to have an almost full airline on the way to Canada and back to India. Would make sure you have a plan b but it sounds that at least she has family to stay with if she gets stuck.
