"Science Rendezvous is an annual festival that takes science out of the lab lab and onto the street! We work with Canada’s top research institutes to present a coast-to-coast open house and festival that is free for everyone. With over 300 events across 30 cities and 1000’s of mind-blowing activities, Science Rendezvous is Canada’s largest celebration of the amazing feats of science and engineering happening right here at home."
We attended last year with our kids and it was fantastic. Check the website for events close to your home.
