have you looked into free program at YMCA. Not sure where you are in Canad, but in most big cities, YMCA offer great program.
Have you trying to contact your city to see if they have any free program offer this summer. Like where I live, they have an intro to tennis offered for the next 4 weeks and they are also running different of volunteer walking/running program. There are also different exercises you can do using park equipment like benches and things like that.
Check with friends to see what they are doing? You might find a friend that has some equipment at home and is knowledgeable on using it and is looking for company while exercising.
