Since 2019, the Government has ensured it is no longer free to pollute by establishing a national minimum price on carbon pollution starting at CAN$20 per tonne in 2019, increasing yearly at CAN$10 per tonne to CAN$50 in 2022. UPDATE 2023: The price will increase by CAN$15 per year from 2023-2030, to a total of CAN$170 in 2030.
