Well, thank you very much for the question.
I think that in this context, you might be touching upon one of two or three different aspects or features of the withholding tax changes. And if I may, I'll address all three, for the sake of comprehensiveness.
First of all, the withholding tax change, for the benefit of all committee members, eliminates withholding tax on arm's-length interest. That is interest paid by a Canadian--it works in both directions, of course, but I'll give you the example of interest paid by a Canadian--to a U.S. lender.
Currently, when interest is paid in those circumstances, the income tax treaty between Canada and the U.S. allows a maximum withholding tax of 10% to apply. There are many exceptions to this already in our domestic law in the case of arm's-length payments, but the treaty itself allows a maximum of 10%.
The same result currently is allowed under the income tax treaty for payments made by Canadian payors or borrowers to related party lenders. This might be the example of a Canadian subsidiary of a U.S. corporation borrowing money from the U.S. corporation. In that case, the interest payments the Canadian company makes to its parent would be subject, under the treaty, to a maximum of a 10% withholding tax.
The protocol proposes to eliminate withholding tax in both those cases. In the case of arm's-length interest to unrelated parties, the withholding tax is to be eliminated in the year in which the protocol takes effect. Some committee members may be aware of the fact that the 2007 budget legislation, recently introduced and recently considered by the finance committee, actually includes a parallel change to provide the same withholding tax exemption worldwide for payments made by Canadians to arm's-length lenders around the world, and furthermore, to make that change applicable as of January 1.
I raise that because one of the issues that has been raised is the uncertainty of when the withholding tax change would come into place. The budget legislation attempts to answer that question, not just for the U.S. but worldwide, by stipulating that it will apply as of January 1.
Finally, you ask about the implications of this, whether there'll be any reverberations or problems from or effects from eliminating this withholding tax. We think that the answer is yes, but we think they're positive effects. As I've mentioned, there are a number of exceptions already in our domestic legislation for withholding tax for arm's-length payments made to non-residents. What the treaty does, and what our complementary change to our domestic law does, is make that exemption universal. What that does, frankly speaking, is take a lot of tax advisers out of the equation who would often be working to get around the existing rules anyway. It also makes clearer or simpler the lending market so that Canadians have more competition and are able to benefit from more competition, both from lenders in Canada and in the U.S., and indeed, from third countries. So we do think that there are effects, but they are positive ones.
