The government may be forced to bring MPs back to the House of Commons after the Canada Day long weekend to vote on the controversial doctor-assisted death legislation, CTV News has learned.

It would be the first time in decades Parliament would hold a summer session.

“It’s a scenario we're planning for,” said a government insider.

The government had hoped to pass the legislation before the Supreme Court deadline of June 6.

But a series of setbacks -- including a full day of apologies after the Prime Minister elbowed an opposition MP -- squandered precious debate time to meet the deadline.

Government House Leader Dominic LeBlanc told CTV’s Question Period he expects the bill to come to a vote on Monday, May 30, when parliament resumes.

But getting it passed in the Senate presents a new series of challenges – including independent Liberal Senators who were booted from caucus by Justin Trudeau.

“Many Senators have very strong views, opposing views, not all the same views about this bill,” said Independent Liberal Sen. James Cowan.

Conservative Sen. Bob Runciman said he sees “no way” that the June 6 deadline set by the Supreme Court of Canada for legislation will be met.

“I think (Sen. Cowan) and I agree that's not the end of the world,” he added.

Sources tell CTV News the Senate Committee of the Whole will study the Trudeau government’s assisted-dying bill and may take several weeks before making amendments and other changes.

That expected hold-up in the Senate would likely force parliament to be recalled in July – a time when MP’s are busy in their constituencies or on vacation.

The June 6 deadline already represents a delay. The Supreme Court of Canada ruled in February 2015 that the government must – within one year -- put in place assisted-death legislation for people facing intolerable physical or mental suffering.

The Liberal government asked for a six-month deadline in order to study the issue before proposing its legislation. Patients’ advocates argued against moving the deadline, but the top court gave the government four more months.

Wanda Morris, a former CEO of Dying with Dignity Canada, told CTV News Channel when the delay was granted that she felt “gutted for those individuals … waiting right now wanting to have the certainty, the peace of mind that they will soon have the choice to have a peaceful death.”
