Canadian author Louise Penny announced a boycott of the U.S. in response to President Donald Trump’s new tariffs on Canadian goods, calling it an “unprovoked trade war.” In a statement on Facebook, the bestselling novelist said she will not enter the U.S. until the economic policies threatening jobs and livelihoods are reversed.

Trump initially imposed tariffs on Canadian and Mexican imports but later rolled some back. However, he is now considering new tariffs on Canadian dairy and lumber. Canadian Prime Minister Justin Trudeau has criticized the move as “a very dumb thing to do.”

Penny, known for her Chief Inspector Armand Gamache series, said the decision to stop visiting the U.S. is “painful” but necessary. She has canceled all in-person events in the country, including a planned book launch at Washington, D.C.’s Kennedy Center. Instead, she will host the event for her upcoming novel, The Black Wolf, at Ottawa’s National Arts Centre on October 28.

She clarified that her boycott is not meant to punish Americans but to stand in solidarity with fellow Canadians. She encouraged U.S. readers to attend her Canadian events, promising a warm welcome.

Penny’s Chief Inspector Armand Gamache books inspired the 2022 Amazon Prime miniseries Three Pines, starring Alfred Molina. She also co-wrote State of Terror with Hillary Clinton, a political thriller about a newly elected U.S. president and a global crisis.
