There was a @winstarjarvis article in @TheWindsorStar out on Christmas Eve about NavCanada's review of YQG:

In it, she said "Airport traffic jumped 300 per cent between 2009 and 2019, 25 per cent in the last three years."

In a @CBCWindsor article the same passenger numbers are quoted. Additionally that "Windsor is the largest on the list by 50 per cent" compared to the other airports being reviewed. https://www.cbc.ca/news/canada/windsor/review-by-nav-canada-puts-windsor-international-airport-control-tower-at-risk-for-shut-down-1.5809054

Keep in mind though when you read numbers like that, it is just one metric. In terms of aircraft movements, Windsor is the second lowest NavCanada controlled airport in the country. The other airports on the list are in the bottom 12 of 40.
