Canada could reduce corporate tax to zero and it would make squat difference.  The non-tax burden in this country is punitive.  EI, pension plans , maternity leave, extended health, Workers comp etc, not to mention lower per hour worker productivity, immense regulatory burden and higher wages  means that we are competitive in the US market if, and only if our Loonie stays low.   Poloz and crew know this and cannot raise rates in case the loonie strengthens thereby crushing GDP growth.

The irony of course is that the BOC low interest rate policy is a primary driver in Canada's over heated housing market.   So the downtrodden but well paid masses have a cheque to cash but no home to live n.

There's no free lunch, comrades.
