If this actually goes down this would have been a good time to implement the format that TSN seems to suggest 18 times every year where D1A promotes immediately to the tournament 2 weeks later. Relegate someone this year and with the lower levels cancelled there would only be 9 teams for next year so you could play D1A mid December 2021 as usual and whoever wins promotes the same roster to the WJC starting December 26, 2021. Of course that has issues with players being gone from club teams for over a month.
