The Canadian Press Heritage Minister Melanie Joly said Conservative MP Gerry Ritz hasn't

In the twilight of his career as an MP, Gerry Ritz is seemingly giving less of a hoot about what he says in public. Not even a week after he was engulfed in controversy for referring to a federal minister as "climate Barbie," the veteran Conservative linked Shariah law to the Liberals' handling of ongoing NAFTA renegotiations on Monday. The MP for Battlefords-Lloydminster tweeted the eyebrow-raising comment in response to a Toronto Sun op-ed titled "Stop normalizing Shariah law in Canada."

Ritz's remark was an apparent jab at the Liberal government's demand to maintain NAFTA's cultural exemption, a provision that protects Canadian arts and culture, broadcast and publishing industries. His comment didn't impress the minister responsible for those files. "I am surprised that Mr. Ritz hasn't learned his lesson about making inflammatory comments," Heritage Minister Mélanie Joly told HuffPost Canada. "We are firmly dedicated to the protection of our creative sector and that includes the defense of the cultural exemption in the NAFTA negotiations, a provision that allows Canada to continue to support our domestic cultural industries," she said. "We have and will continue to stand for our artists and creators."

Two days after Ritz's tweet, Conservative Party Leader Andrew Scheer called McKenna to apologize. Ritz's office did not respond to a request for comment by publication time. Neither did Scheer's. Last year, Ritz's words got him into some hot water after he accused then-international trade minister Chrystia Freeland of having a "meltdown" during trade talks. The next day, he suggested Freeland needed "adult supervision." Freeland responded by confirming to Ritz that she is in fact an adult, saying, "I am 48 years old — I think I have the wrinkles and the grey hair to prove it."
