Vancouver is known as Hollywood North :). This happens probably due to tax-benefit/break and government support for the film industry (correct me if I'm wrong) that makes movie production cheaper in Vancouver.
And yes, there aren't many big hi-tech companies in Canada. Most of them are at most a few hundreds employees, which I supposed is big enough considering the ratio of population compare to US (roughly 1:10).
I can't imagine there's a hi-tech company with 1k employees in Vancouver. Very very hard. I don't think there's even a 1K (Canadian) company in Vancouver regardless of the sector.
