First I'll comment on your comment about targeted tax measures. Some are good. CGA Canada is not against all of that. As a policy, RRSPs are good, for example, but they're targeted, so that's good to allow people to retire.
For corporate tax, I understand from my own experience that when a client has an increase of 2% in corporate taxes, for example, he still has the same financial projections he gave the bank two years ago. The rates are announced in advance and he makes his financial projections based on those rates. When there's no stability in the system and it changes all of a sudden, that person will still have the same payment on the business.
So what will he do? He will pass that 2% increase on to the customer. So at the end of the day, the taxpayer will pay, not the corporate entity, because it still has the same capital requirements. It's my personal experience that the taxpayer ends up paying the corporate tax increase anyway.
