TORONTO -- TORONTO - Three of Canada's premiers will announce Sunday a plan to fight climate change by working together on small nuclear reactors, a company that's developing the technology said Saturday.

New Brunswick-based ARC Nuclear Canada said in a news release that its president will attend a signing ceremony Sunday between the provinces of New Brunswick, Ontario and Saskatchewan to work in collaboration on the modular reactors "in an effort to mitigate the effects of climate change."

The Ontario government said Premier Doug Ford will meet with Saskatchewan Premier Scott Moe and New Brunswick Premier Blaine Higgs for an announcement at a hotel near Pearson International Airport on Sunday afternoon.

A spokesman with Moe's office confirmed the announcement is connected to an agreement on technology for small modular reactors, while a spokeswoman for Ford's office said it's an agreement to work together to determine the best technologies for the deployment of small modular reactors in Canada.

Moe said earlier this month that nuclear power has to be deployed in a big way around the world to significantly reduce greenhouse gas emissions, noting his province is well positioned to support more nuclear power with its large reserves of high-grade uranium ore.

All three of the premiers are opponents of the federally mandated carbon tax.
