Until now, only nine communities in remote areas of northern Saskatchewan and northern Ontario were in the running to host the $24-billion project for a mammoth underground facility.
Now, to the consternation of some, one of southern Ontario's premier tourist destinations is on the radar, although how it got there is already the subject of dispute.
The municipality of Saugeen Shores, which includes the picturesque lakeside towns of Port Elgin and Southampton about three hours west of Toronto, is showing interest in becoming home to the waste site.
Neighbouring Brockton is also looking to get on board as part of an initiative to involve the entire county, which is already home to the Bruce nuclear power plant in nearby Kincardine.
