With exactly four weeks to go until the House of Commons is scheduled to power down for the summer, the no-longer-minority Liberals are poised to force a make-or-break vote on Finance Minister François-Philippe Champagne’s pitch to roll out measures unveiled in his inaugural spring fiscal update.

Just before MPs headed out on the now-wrapped two-week mid-May hiatus, the Liberals served notice that they were prepared to bring in a motion to set a deadline to wind down second-reading debate, which could be called as early as tomorrow morning — which, depending on how the ensuing back-and-forth plays out, could see it hit committee later this week.

Also on the docket tomorrow: A vote on a Conservative-initiated call for the government to “put private property first” in the wake of a landmark B.C. court ruling on Aboriginal title claims. (Monday p.m.)

If adopted, the motion — which was debated just before the chamber shut down for the two-week hiatus — would call on Prime Minister Mark Carney to instruct federal lawyers to “aggressively defend property rights in all litigation” and “publish a plan within 30 days to protect property rights for Canadians affected by the Cowichan decision and Musqueam agreement (with) specific commitments and timelines.”

It would also create a new special committee “with the mandate to study all legal, constitutional and political steps that can be taken to protect private property rights in Canada,” which, as per the terms outlined in the motion, would be chaired by a Conservative MP and would hold “at least 12 meetings” before June 19, which would also serve as the deadline to file an “interim report” on its findings.

The Conservatives are also on track to take control of the House of Commons agenda on Tuesday — and possibly Thursday as well, as both have been tentatively designated as the fifth and sixth opposition days of the current supply cycle, with the last two to be held by June 23, which is the deadline for MPs to approve — or, alternately, reject — the latest estimates.

As of Friday afternoon, the Conservatives had put two non-binding motions on notice, one of which calls on the government to “keep the Snowbirds in the air through 2030, and make sure that they have replacement jets, not prop planes, by that date,” while the other challenges the Liberals to “offer Canadians immediate relief by ending all federal taxes on gas and diesel for the rest of the year, including the GST, and permanently scrap the Clean Fuel Standard.”

Both motions were put forward in the name of Conservative leader Pierre Poilievre, and the party will have until Monday afternoon to decide which to call for debate on Tuesday.

Also on the radar: As has become tradition during the spring sitting, the opposition parties — or, to be scrupulously procedurally correct, the Official Opposition, in consultation with the other recognized parties — have duly selected two Team Carney front benchers to field questions on the latest estimates filed under their respective ministerial purview during separate committee-style session on the floor of the House of Commons.

First up: Finance Minister François-Philippe Champagne, who will spent up to four hours being cross-examined by his cross-aisle colleagues on Tuesday evening, with Citizenship and Immigration Minister Lena Metlege Diab expected to face the chamber later this week.

Several of their cabinet colleagues will be hitting the estimates circuit at committee, including Justice Minister Sean Fraser, who will also be quizzed about his “priorities and mandates” during a morning appearance at JUSTICE AND HUMAN RIGHTS (Monday a.m.), Housing and Infrastructure Minister Gregor Robertson at HUMAN RIGHTS, SKILLS AND SOCIAL DEVELOPMENT (Monday p.m.) and Industry Minister Mélanie Joly at INDUSTRY AND TECHNOLOGY (Monday p.m.)

As for the prime minister, a just-in notice from his office reveals that he’s heading to New York later this week to “position Canada as an investment hub” during a two-day visit that will include meetings with “top CEOs, entrepreneurs, business leaders, and capital managers to position Canada as a premier destination for new investment,” as well as a speech hosted by the Economic Club of New York. (Wednesday through Thursday)

Elsewhere on the committee roster: PUBLIC SAFETY AND NATIONAL SECURITY members continue to parse the fine print of Public Safety Minister Gary Anandasangaree’s latest bid to overhaul Canada’s lawful access regime during an extended session that will include back-to-back presentations from Barreau du Quebec president Marcel-Olivier Napier, Privacy Commissioner Philippe Dufresne, Crypto Quebec co-founder Luc Lefebvre and Brampton Mayor Patrick Brown, senior officials from Apple. Inc. and Google, representatives of the Canadian Civil Liberties Association, Canadian Association of Chiefs of Police and the Ontario Child Sexual Exploitation Investigators Association and Peel Regional Police deputy chief Nick Milinovich, among others. (Tuesday p.m.)

Over at PROCEDURE AND HOUSE AFFAIRS, MPs get ready to wrap up their lightning-round review of proposed changes to the federal election laws with a final round of expert testimony from lawyer Gerald Chipeur, Democracy Watch co-founder Duff Conacher and Cornell University’s Peter Loewen (Tuesday a.m.) before moving to clause-by-clause later this week. (Thursday a.m.)

With the bill seemingly on the fast track through the House of Commons, the Senate LEGAL AND CONSTITUTIONAL AFFAIRS committee has blocked off an hour to quiz its sponsor, Transport Minister Steven MacKinnon, as it kicks off its preliminary review of the draft legislation, with Chief Electoral Officer Stéphane Perrault and Canada Elections Commissioner Caroline Simard also expected to be at the table. (Wednesday p.m.)

Members of the opposition-chaired ACCESS TO INFORMATION, PRIVACY AND ETHICS committee will assemble to discuss Champagne’s response to the committee’s open-ended invitation for him to appear before the committee this week to field questions on his decision to recuse himself from decisions related to to the Alto high-speed rail project, which, as of Sunday afternoon, did not appear to have been scheduled as yet.

AGRICULTURE AND AGRI-FOOD members resume their ongoing study of “business risk management programs” within the agriculture sector with Ontario Federation of Agriculture senior economist Ben LeFort and Conseil pour le développement de l’agricutlure du Québec general director Sarah Delisle. (Tuesday a.m.)

On the Senate side: As flagged by iPolitics’ own Marco Vigliotti and Sydney Ko last week, ENERGY, ENVIRONMENT AND NATURAL RESOURCES members are on track to wrap up clause-by-clause review of S-4, a “sweeping update of the Energy Efficiency Act,” which was initially passed in the early 1990s, that “aims to streamline how new household appliances enter the Canadian market by giving the minister greater flexibility to update standards,” as well as “grant temporary exemptions for innovative products.” (Tuesday p.m.)

Introduced in the Senate last fall, the legislation has been working its way through committee since mid-April, which has “thrown a wrench into the government’s plans for consumer rebates,” iPolitics notes, citing a government source.

Although the committee is expected to wind down clause-by-clause review this week, “it may not be enough to get S-4 past the finish line before Parliament rises for the summer in mid-June,” the source warned.

Meanwhile, HUMAN RIGHTS members have blocked off at least four more hours to survey expert witnesses on Fraser’s contentious proposal to expand and update Canada’s anti-hate laws, with representatives of the National Council of Canadian Muslims, Canadian Council of Imams, Canadian Muslim Lawyers’ Association, Canadian Muslim Healthcare Network, Egale Canada, DisAbled WOmen’s Network of Canada and Black LGBTQ Justice Canada among the invited witnesses.
