The tournament is the first of its kind in Canada, and it's hoped it will help spread the game into North America.
There are six teams competing - Vancouver and Toronto with Cricket West Indies B Team, Edmonton Royals, Montreal Tigers and Winnipeg Hawks. Each team will play against each other twice before the tournament moves to the playoffs.
Each team features four Canadian cricketers in each squad, along with international players.
The International Cricket Council (ICC) sanctioned the tournament in February 2018, and it will be the first T20 league in North America. Justin Trudeau, Canada's Prime Minister, was pleased with the ICC's decision to approve the league.
The Global T20 Canada League has Cricnwin as its fan engagement partner for the inaugural edition.
