The federal government has pushed its target to achieve a net-zero electricity grid to 2050.
The government had previously aimed to fully decarbonize electricity grids by 2035.
But some provinces, namely Alberta and Saskatchewan, said that was simply not doable.
The final clean electricity regulations published today also projected a lower reduction of greenhouse gas emissions than had previously been forecast.
Committing to a net-zero electricity grid is an easy move for six of the provinces, which are already more than 90 percent of the way there.
Alberta, Saskatchewan, Nova Scotia and New Brunswick still rely on coal and natural gas to supply between 30 percent and 85 percent of their power.
