Tory Whip Jay Hill said the decision meant immediate expulsion from the caucus.
"Mr. Casey was well aware of the consequences before he cast his vote," Mr. Hill said.
But Mr. Casey seemed less certain. "I'm still a Conservative," he said. "Peter MacKay said they wouldn't throw anybody out of the caucus if they voted their conscience on [the budget bill]. Although the Whip just gave me a little different message a minute ago."
Last month, Mr. MacKay told the House: "We will not throw a member out of caucus for voting his conscience. There will be no whipping, flipping, hiring or firing on budget votes as we saw with the Liberal government."
