"Right now, 8% of Federal Revenue pays just the interest on that debt. If interest rates go up, say in a year or two.. so goes up that payment."

Canada has a fiat currency. Thus the Canadian government can set the interest rate on federal debt to zero.

Permanent ZIRP (zero interest rate policy) is probably a better policy since it reduces the compounding of debt and the tendency for the rentier class to take over more of the economy
