Oh, for Heaven's sake.
.
The two biggest productivity drags:
.
1. The 90-minute/day commuter congestion tax paid by every person and every business.  The main effect of that enormous tax on everybody's lives is to prop up gas sales - so the Oil Party does everything to stymie construction of public transit.
.
It costs $30/day for a car in the GTA.  For 70 cents/person/day we could build everything Metrolinx has ever wanted.
.
For the Oil Party, the $30/day must-own-a-car tax is fine, because the GTA is the 4th largest gas market in N. America, whereas 70 cents/day on public transit is Godless Communism:  "No New Taxes"!
.
2. Despite cities being the job-creation bee-hives of the knowledge-based economy, Canada has a tax system hopelessly skewed to subsidize resource extraction and banking at the expense of everybody else.
.
The main beneficiaries?  You guessed it: the Oil Industry - yet again.
.
That is what is holding our economy back.
.
Want better productivity?
Stop subsidizing oil.
