He and several caucus members had gone into isolation after a staff member tested positive on September 14. Blanchet’s wife, Nancy Déziel, began developing symptoms and tested positive on September 15.

The Bloc Québécois news release stated that Blanchet is reminding Québécois to follow health guidelines if they develop symptoms or have been in close contact with confirmed cases.

Accordingly, he won’t be able to attend, in person, the throne speech in the Senate when Parliament returns on September 23. 

Meanwhile, Conservative Leader Erin O’Toole and his family have also gone into isolation as O’Toole awaits test results, after one of his staff members tested positive on September 16.

O’Toole, who was elected leader on August 24, criticized the state of COVID-19 testing after he and his family waited for hours to get tested in Ottawa on September 16, but were unable to receive testing due to capacity limitations. Consequently, he had to go to Gatineau, Quebec, on September 17 to get tested.

Early on in the pandemic, Sophie Grégoire Trudeau tested positive for the coronavirus on March 12 after a speaking engagement in London, England. Consequently, Prime Minister Justin Trudeau went into isolation for 14 days. According to a statement from the Prime Minister’s office, he was not tested, based upon medical advice, as he did not develop symptoms.
