The construction and commissioning of most of California's impressive wind energy super-farm in the "wind tunnel" between Palm Springs and Los Angeles preceded the carbon tax.

And other states, notably Arizona which I am very familiar with, have seen explosive growth in solar power adoption. Texas is seeing double digit annual percentage growth in wind and solar power.

Tesla is focused across many western states (including California), and while benefitting from generous tax measures is not reliant on carbon tax dollars (or penalties).

Carbon taxes do not and will not foster investment or  innovation in clean energy. They will lower consumption of fossil fuels, but in Canada this will simply lead to lower incomes and standards of living. 

Incentives, not penalties. The promise of profit is superior, always.
