Also living in Paris - from Canada. Also with no tickets to anything. Went to the Parc des Champions (free) which was very cool and felt like I was at an event :) The line can be a while but I was fortunate after 19:00 and got in.
I recommend a visit to the Parc des Buttes Chaumont. It's a real corner of nature, designed by an architect working for Haussmann. The most beautiful park in Paris.
