The proposed changes remove most of the incentives to retain earnings in a CCPC - so the change in corporate tax is really just salt in the wound as it doesn't address any of the issues the changes pose and is the cancellation of a cancelled tax cut.
I'd consider myself "Liberal Biased" (at least federally) and I can't see myself being able to forgive the issues around the massive deficits, conflicts of interests, populist politics, etc. The tax system needs review and reform, but that review and reform has to be thoughtful, it has to make life better for Canadians - it has to support the economic engines in this country. Tax reform should make tax administration and compliance easier - while ensuring the government has enough revenues to perform its duties.
