reminds me of American "made in Canada movies" ... in several scenes in the start of one movie, they removed images of the CN Tower when taken of the skyline from the Islands. Towards the end of the movie there were a couple scenes where they didn't even bother to maintain the illusion.
Then there was Short Circuit 2, where Ben got his US Citizenship (with American Flag flying proudly) on the steps of Queens Park!
and dare i say it one of the most popular sci fi shows of the last 20 years WAS mostly made in canada stargate sg1 as was andromeda and you can continue looking into it. YOU will see a lot of the sci fi was and is canada. Americans can't do math so don't expect any good sci fi....
Stargate SG1 was popular? God, that was a terrible series. Andromeda wasn't bad but it was worth watching.
