Charlottetown MP Sean Casey lost his position as parliamentary secretary to the minister of veterans affairs after supporting an NDP private member’s bill targeting arms exports to Israel. The Prime Minister’s Office announced on Friday that Quebec MP Sophie Chatel will replace Casey following his vote in favor of Bill C-233.
The Conflict Over Bill C-233 and Party Discipline
In March, Casey stated he received a warning from the Liberal whip regarding potential removal if he backed NDP MP Jenny Kwan’s Bill C-233, also known as the No More Loopholes Act. Fifteen Liberal MPs broke rank to support the legislation, but Casey was the only parliamentary secretary among them. Parliamentary secretaries earn $20,900 above the base MP salary of $217,700 and represent ministers at public events.
And that’s what my constituents were concerned about."

Discussions With the PMO and the Liberal Platform
Casey reported receiving a telephone call from the Atlantic desk of the Prime Minister’s Office on Thursday informing him of his replacement. He characterized the discussions with both the whip and the PMO as direct and explicitly tied to his support for Kwan’s bill. Over the subsequent six months, Casey noted he wondered if disciplinary action would occur.
He maintained that his understanding of the 2015 Liberal platform, which brought the party to power, entitled backbench MPs to a free vote on private member’s bills unless matters involved implementing the platform, traditional confidence issues like the budget, or Charter-guaranteed protections.
Reactions and Future Outlook in Parliament
The Prime Minister’s Office did not immediately respond to a request for comment regarding the shuffle. Because more than a dozen Liberal MPs supported the legislation, the vote did not appear to be strictly whipped, and the bill ultimately failed.

In a statement, Kwan described the removal of Casey as distressing and a matter that should concern all Canadians. She argued that the incident raises serious questions about the government’s commitment to letting MPs exercise independent judgment. "The prime minister talks a good talk, but in reality, he will wield his power to shut down dissent," Kwan said.
Casey indicated that the disciplinary measure will not deter him from representing his constituents in the House. He noted that the change leaves him somewhat liberated from strict party lines while retaining tremendous respect for the prime minister and affection for the Liberal Party.
