Canadian Prime Minister Justin Trudeau said he will visit Atlantic Canada regions affected by Fiona "as soon as possible this week," while indicating the desire not to interfere with any emergency response efforts, stating there will be input from everyone. Trudeau said during a federal update on storm response efforts on Monday: "The one constant in my calls with premiers, mayors, and MPs is that Canadians are stepping up for each other and helping their communities get through this difficult time."

Atlantic Canada experienced a post-tropical storm on Saturday, causing widespread destruction, fallen trees, and extensive power outages due to strong winds and coastal flooding. Also, in Newfoundland and Labrador, where the body of a 73-year-old woman was recovered Sunday afternoon after the storm swept homes away in Port au Basques, the Minister of Rural Economic Development said on Monday that 76 homes have been destroyed or structurally damaged, adding: "It will be a long time before this area gets back on its feet," describing what she saw firsthand as "painful" while urging those evacuated not to try to return to their properties to retrieve personal belongings until local authorities declare it safe.

In Prince Edward Island, major tourist sites appear to have suffered severe flooding and erosion, and one person died, with preliminary investigations indicating that generator problems may have played a role. As in the rest of the region, hundreds of thousands of residents in Nova Scotia remain without power, although reports of serious injuries are sparse. Nevertheless, Canadians will be left cleaning up significant property damage for some time, including parts of New Brunswick and Quebec’s Magdalen Islands.

Trudeau said on the same subject: "The storm has passed, but thousands of homes are still without power, and the extent of the damage means people are still facing tough times." Hundreds of Canadian Armed Forces personnel have been deployed in Nova Scotia, Prince Edward Island, and Newfoundland and Labrador to clear debris and help restore electricity, communications, and power across the Atlantic provinces.
