Carney has quite a unique opportunity for massive public spending that would have never been popular in any other case. The US always kept Canada well enough that the economy was "good enough" with declining infrastructure and underinvestment (capital fleeing to better return in the states).

Now that he can claim to have no choice and people are really mad, then he can even force retirement funds to invest massively here through those "nationnaly important projects". If successful that would seriously boost our stagnant productivity and economy.
