Wikipedia:Articles for deletion/Canadian Arena League
I am seeing two OK sources about the announcement: http://www.570news.com/2017/11/28/group-hoping-get-football-indoors-waterloo-region-identified-potential-market/ this and https://theathletic.com/196116/2018/01/04/an-idea-for-an-arena-football-league-in-canada-that-is-only-missing-a-couple-of-things/ this. There is also a bit of more  coverage in http://www.oursportscentral.com/services/releases/weekly-sports-league-and-franchise-report/n-5288939 this. I would likely say it is  as they don't have a single team and have not generated much in the way of coverage from very reliable sources. But others may feel differently
