Canada is announcing a plan to phase out the use of coal-fired electricity by 2030.
Currently, 80% of Canada's electricity is produced from clean sources such as hydroelectric power, nuclear, wind and solar.
N.S. Premier Stephen McNeil said the exception being made for his province represents fair recognition of his government's work to reduce greenhouse gas emissions.
Nova Scotia will also adopt a province-wide target that meets or exceeds Canada's target of reducing emissions by 30% over 2005 levels by 2030.
Meeting the coal-cutting targets will be hard for those provinces as the transition may be costly, even with the flexibility the federal government granted, said Joe Aldina, director for USA coal for the PIRA Energy Group.
At the same time, below Canada's southern border, President-elect Donald Trump has promised to bring back coal jobs and bolster the industry through cutting energy regulations aimed at lowering the United State's carbon emissions.
While he believes the government should spend money on research and technology to find ways to reduce coal emissions, Campbell also said the fossil fuel should continue to be a major player in power generation.
"We know the world is moving to a low-carbon future", Ms McKenna said.
At least in the case of Nova Scotia, however, the federal push seems like more of a gentle nudge.
"Saskatchewan will be evaluating both the environmental and the economic impact on our province of today's federal government announcement", the province's Premier Brad Wall, who claims the national government has betrayed its commitment to consult provinces on climate matters, told Reuters.
In Canada, provincial governments have jurisdiction over the generation and transmission of electricity.
Coal power in Alberta, Saskatchewan, New Brunswick and Nova Scotia accounts for 10% of Canadas total greenhouse gas emissions.
Key measures to boost the transition include stricter carbon rules for new coal-fired units and units older than 50 years. Exports to Canada roughly tracked with that trend, falling 27.4 percent, from 2.5 million short tons in the first six months of 2015 to 1.8 million in the first half of this year.
The move to accelerate weaning Canada off coal comes as Austria, Britain, Denmark, France and the Netherlands do the same. "Their proposed approach ensures that Nova Scotia will remain a leader in contributing to Canada's global emissions-reduction target under the Paris Agreement". Even so, the Wall Street Journal notes it is the world's 12th largest coal producer and a major consumer of USA -mined coal.
