The latest battle in Ontario's war of words with the federal government over carbon pricing is focusing on the costs to public institutions, like colleges and universities.
The province estimates that the federal carbon pricing plan will cost Algonquin College an extra $151,000 next school year, while costing Carleton University an added $415,000.
"This is an unaffordable tax," said Dr. Merrilee Fullerton, Minister of Training, Colleges and Universities. "An unaffordable tax for our institutions, for our students, and for all Ontarians."
Fullerton believes carbon pricing will take money away from programs and equipment for post-secondary students.
The University of Ottawa was not included in the Ford government's estimates, because it does not use the types of fuel included in the calculations.
Minister of the Environment Rod Phillips pointed to the Ford government's environment plan, which he said would allow colleges and universities to decide whether or not they wanted to opt in.
Liberal MP for Ottawa West-Nepean, Anita Vandenbeld, accused the province's PC government of misleading the public on climate change.
"Putting a price on pollution works and is the right decision for families and businesses," Vandenbeld wrote in a statement. "We know that investing in clean growth creates economic opportunity, and we built our plan to encourage companies to innovate."
Ontario and three other province's have taken the federal government to court to launch a constitutional challenge over whether the federal government has the authority to implement its carbon pricing plan.
