I think our own system that we have in place right now is what is attracting foreign investors: we have advantageous tax rates globally.
What is more difficult, though, is that if you have large corporations they will usually work in all provinces. I believe in 2008 a study was done by PricewaterhouseCoopers, if I'm not mistaken, which showed that if you had a place of business in all these provinces, you would have 295 taxes to comply with. So is that attractive in and of itself? No. I think that's where tax simplicity would be more attractive.
As a globally well-positioned country, yes, we are; on the taxation compliance side, maybe less.
