Years after voicing its opposition to an Ontario nuclear technology company disposing of nuclear waste near the Ottawa River, a group of Montreal-area mayors is still not on board with the project. Now, it's expressed its concerns during a public hearing. In 2018, dozens of mayors with the Montreal Metropolitan Community (CMM) unanimously adopted a motion to oppose the development of a permanent nuclear waste disposal site in Chalk River, Ont., about 180 kilometres northeast of Ottawa.
