If the author is concerned about productivity, then the most effective step is to reduce congestion in our urban areas.
.
Congestion is an enormous tax that hobbles labour force mobility, and increases the transaction costs of every economic activity that involves getting goods, services, or personnel to the right place at the right time.
.
Congestion hugely constrains economic choice:  If you can't be sure that your delivery driver can get back from Oakville before the end of the day, you waste  a lot of your time trying to plan delivery routes and schedules to avoid traffic, and you are less likely to do business in, e.g., Oakville.
.
It effects, and limits, economic choices.
.
The solution is European-intensity public transit.
.
But that is what the Oil-company-owned Conservatives have spent two decades fighting tooth-and-nail to prevent because Oil companies profit from congestion  - at the expense of the entire population.
.
It is a huge tax.
It is a productivity killer.
