Quebec will implement Canada’s first carbon tax in October, collecting just under 1¢ a litre from petroleum companies in the province, which will raise about $200 million a year to pay for energy-saving initiatives such as improvements to public transit.

The tax will amount to 0.8 cents on every litre of gas sold in Quebec, and 0.9 cents on each litre of diesel fuel.

About 50 companies will be affected by the tax.

Oil companies will be hardest hit. They will pay about $69 million a year for gasoline, $36 million for diesel fuel, and $43 million for heating oil.

Natural gas distributors will pay about $39 million, while electricity distributor Hydro-Québec will pay $4.5 million for its thermal energy plant in Tracy, Que.
