Mr. Bernier supports an inflation target of zero.  This is the same policy that Volker pursued in the US which created high unemployment and stagnation.  The money supply needs to grow at roughly the same rate as GDP because - money facilitates transactions.  The rate that has produced the most stability is found in the 2% inflation target.  The money supply also needs to grow to support productive investments, again, otherwise you slip into recession.  If there is not enough money to cover all of the GDP transactions/investments then what you get is a recession.  Add to that the fact that Canada would be permanently at the Zero Lower Bound and anyone can see this is a really bad, even crazy, idea.
