This is the first article I have seen regarding runaway production in Animation and VFX that makes any sense to me. If you are trying to build an industry in a region and expect incentives from the government, it shouldn't be easy to import temporary workers to do the work. You should have to hire the local talent. Of course, the real talent doesn't live there, so you look for loopholes to import people from the states to do the work. Looks like those days of easy imported talent might be numbered for Canada.
"Without the IT category, Pixar, Digital Domain, Ubisoft and the like will, starting in October, have to apply for temporary work visas the way every other company in any industry does. This means first seeking a so-called Labour Market Opinion (LMO) from Ottawa's Service Canada department. It requires demonstrating that a position meets wage guidelines, brings new skills and knowledge, and does not adversely affect the employment of a Canadian worker."
