Four local cities have officially announced their intentions to team up and bid to jointly host the 2021 Canada Summer Games.

The Canada Games Council announced Tuesday that it had received confirmation of intent to bid on the games from four communities.

Included in that list is a combined bid from Kitchener, Waterloo, Cambridge and Guelph, as well as separate bids from Ottawa, Greater Sudbury and Niagara Region.

Bidders have until the end of June to provide organizers with preliminary information, and until January 2017 to submit their full bid proposal. The host will be chosen by April 2017.

The Canada Summer Games were last held in Ontario in 2001, when London hosted the event.

According to the Canada Games Council, the 2013 Canada Summer Games in Sherbrooke, Que., brought that community an economic impact of $165 million.

That edition of the games – the most recent summertime one – featured 4,200 athletes in 20 different sports.
