No. We don't have an estimate of what the maximum threshold is, but what we provided in that report was basically a comparison over the last, I think, 25 years. We projected that if, as expected, the Bank of Canada's interest rate rises back up to about 3%, which is the mid-point of its estimates for the neutral rate of interest from current levels, we would expect to see household debt servicing rise from about 14.2% of disposable income to 16.3%. Relative to the long-term historical average, that's roughly 3.5 percentage points above its long-term historical average.
