Operations of the two largest salmon farmers on Canada's east coast remained relatively unscathed after post-tropical storm Fiona barreled into the country's coastline in a historic weather event over the weekend.

The storm, which was downgraded from a hurricane Friday, had already pummeled the Caribbean, causing devastation in Puerto Rico and significant damage in the Dominican Republic and the Turks and Caicos Islands, before making its way to the Canadian coast.

Mowi, which has 34 sea sites, three freshwater facilities and two broodstock facilities in the region, was relieved to report all its employees were safe and that its facilities in New Brunswick, Newfoundland and Prince Edward Island, had "only minor damages."
