March 15th was when Trudeau told Canadians to return home asap or risk being stranded. I know because i had to buy a ticket to get my daughter home from Glasgow earlier than planned.
That was a massive amount of luggage, we go south to Mexico for many months, with one carry on and a backpack each. I still have clothes that come back unworn. It is very difficult to handle multiple suitcases, even when not dealing with disabilities. My future advice would be to pack lighter, especially after you experienced this nightmare. I assume you were able to get some help with the bags? I have trouble envisaging you and 7 wheeled bags getting to the hotel alone.
