Well, generally speaking, I do think that corporate income taxes should be kept at a minimum, and those that already have been announced and that business is already counting on I would certainly not backtrack. But also, as Glen pointed out, governments do need revenues, and if we do not raise it via corporate income taxes then there have to be some other ways.
Again, in general terms, if I were the Minister of Finance, which I'll never be, but if I were, I would keep corporate and personal income taxes at the lowest possible level. I would raise consumption taxes, value-added taxes, and the GST.
Now, we know what's going on in British Columbia. Canadians and consumption taxes are an explosive mix, so I understand the practical problems of that, but I think corporate income taxes should be kept at the lowest possible level to keep our competitiveness.
