Harry Potter: The Exhibition ? At the Ontario Science Centre So, in our wonderful city of Toronto there is a Harry Potter exhibition at the Ontario Science Centre. I discovered this a few weeks ago on a billboard near my house but completely forgot to look it up. Now that I have, I have decided I will be going. Apparently James and Oliver Phelps(Fred and George Weasley) were there the opening day in April, which is awesome! Anyway, if you had the opportunity, would this be something you would be interested in visiting?
