Canada Day

"We have Canada Day and Thanksgiving celebrations so we will make Newfoundland food - Jiggs Dinner - for them," says Ms Casey.

The two were seen together publicly at Canada Day events in Ottawa last month.

On Canada Day, about 100,000 people, including Prime Minister Justin Trudeau, made their way to a concert stage in front of the Canadian War Museum for a day of musical performance, occasional speeches and, finally, fireworks.

Across the border, Montreal canceled July 1 Canada Day fireworks, citing poor air quality from the more than 100 wildfires burning across Quebec.

Stephane Guertin of Tandem Communication, which represents the organizer of the Canada Day event, said Thursday that public health officials were unable to say if smog warnings would persist through Saturday.
