Please stop, that is not what happened. During the pandemic, visitors visas were still being processed when the need was immediate (you need to travel right away) for family reunification and other important ( funerals, important business needs) on a case by case basis via a special categorization. That has now ended and what they are saying is that you would be better served by just filing again via a new application likely because IRCCs backend IT is so horrible they cannot re categorize them on their end. No applications or visas have been cancelled or withdrawn forcibly.
Please reach the entire statement, it clearly says,
If you don’t intend to travel to Canada right now
There’s nothing else you need to do. Your application will remain in the queue for processing.
