I think you are wrong and your thinking is clouded by a poor premise that "they will leave".

This has not shown to be true in Europe or the US which have higher personal and corporate tax rates respectively.

The Canadian government has been transferring the tax burden from companies to individuals such that individuals now pay 60% of the taxes collected nation wide.

Certainly extreme raises in taxes could have some affect but a gradual movement back to corporate taxes, including the closure of the Barbados Tax Dodge, would benefit all.

The henny-penny conclusions you make that the sky is falling are not real.
