In the major measures in part 3, there are a lot of what you could characterize as housekeeping measures in the foreign affiliate changes as well. Most of the changes are accommodating, streamlining, simplifying, relieving, and clarifying. The ones that get all the attention, and we're sure the members want to chat further about this morning, involve hybrid surplus and upstream loans. Those are the more significant changes.
Mr. Brison, I will get to your question, but just to provide the necessary context to answer it, the Canadian international tax system, as it relates to certain kinds of income earned through foreign affiliates of corporations in Canada—corporations in Canada, when they're exploiting markets elsewhere in the world, often invest and do that through foreign affiliates—this is a subject matter that involves how Canada taxes that foreign income, be it active business income, passive income, or what have you.
Since the Canadian system was introduced in the 1970s, we've had a component of that foreign income be subject to what we would call a deferral and credit system. That is, the income can be earned offshore and Canada doesn't tax it currently, but it goes into a pool of earnings that the system refers to as taxable surplus, and when the taxable surplus is repatriated to Canada—and it may be repatriated in the same year that it is earned or it may not be repatriated for 30 years—the Canadian system will then impose a residual tax, a top-up tax, to reflect the difference, if there is any, an excess of the Canadian corporate tax rate over the tax borne by those earnings offshore. Therefore, if you earned active income in a jurisdiction that imposed tax at a 5% rate, Canada wouldn't tax it, provided it was active when you earned it, generally speaking. However, when it's repatriated to Canada, we would impose tax on it that would increase the burden to roughly the 25% to 30% rate when you include provincial taxes.
