Last year, the government announced it was giving the provinces and territories until the beginning of September to “outline how they are implementing carbon pricing systems that meet the federal standard.”
Those standards, or benchmarks, demand that a carbon price of $10 a tonne must be implemented this year. That price will increase to $20 on Jan. 1, 2019 and to $50 a tonne in 2022.
