With the House officially, if temporarily, adding a third shift to the daily Commons workday that will keep the lights on in the Chamber until midnight from Monday through Thursday until the parliamentary machinery powers down for the summer, it seems like a good time to check in on the progress of the Liberals’ pre-summer legislative to-do list.

In particular, here’s where things stand on the seven bills most likely to be top priorities for the government, as per Process Nerd’s preview of what to expect from the final weeks of the 42nd parliament.

In fact, as of last night, that number has dropped to six, courtesy of the Upper House, which, as iPolitics’ own Tim Naumetz reports, rejected a last-minute Conservative-led bid to perform a radical rewrite to Public Safety Minister Ralph Goodale’s bid to tighten gun laws that would have effectively undone most of the proposed new measures. These include more stringent background checks and more detailed record-keeping requirements for retailers, but stops well short of imposing a ban on handguns.

C-59 (national security and intelligence regime overhaul)

Goodale’s long-awaited plan to overhaul Canada’s national security regime to address what the Liberals’ 2015 campaign platform described as “problematic elements” introduced via the previous Conservative government’s controversial omnibus anti-terror bill — is also back before the Upper House after a lightning-round review at committee, which made four changes to the text.

Depending on whether the government is willing to accept those amendments, it could join the gun bill in the queue for Royal Assent as early as next week — unless, that is, Goodale advises the House to rebuff the proposed changes.

That would set the stage for a cross-chamber showdown, which could put the bill’s eventual passage in doubt.

It’s also not the only Senate rewrite that may end up on Goodale’s desk between now and the summer recess.

C-83 (solitary confinement)

There’s also his plan to rejig the policies on the use of solitary confinement within federal institutions in the wake of multiple court rulings that found the current protocols to be a violation of the Charter protections against cruel and unusual punishment, which also seems all but certain to be amended at committee, although there’s no guarantee that any changes would make it through a full Senate vote.

Even so, as noted in the original Process Nerd rundown, we’re already well past the deadlines set — and extended — by the courts, which makes the bill’s passage before the whistle blows on the current sitting especially critical.

C-69 (federal environmental assessment) and C-48 (Northern BC tanker ban)

Two other contentious Liberal-backed initiatives — Environment Minister Catherine McKenna’s plan to update and expand the federal environmental assessment process, and Transport Minister Marc Garneau’s bid to ban tanker traffic off British Columbia’s northern coast, are currently predicted to squeak through the Senate.

It’s a good bet that both bills will make a return trip to the Commons, however, as each underwent significant changes at committee in the Senate, although it’s not clear that the Upper Chamber will sign off on the full suite of recommended changes. Whatever changes are adopted, however, will have to go back to MPs for approval, which could delay, if not derail, final passage.

C-93 (expedited pot pardon process)

As for Team Trudeau’s pledge to set up a streamlined, cost-free system to allow those convicted of minor cannabis-related offences to apply for pardons — or, to use the official term, “record suspensions” – which also falls under Goodale’s ministerial aegis, it’s currently heading back to the House after a round of amendments at committee.

Presuming the government isn’t going to push to have those changes reversed — which would be a surprise, what with the amendments having been adopted with the support of Liberal committee members — it could start its journey through the Senate as early as next week. However, without a cross-aisle deal to fast-track it through the next phase of parliamentary scrutiny, that may not be soon enough to get it to Royal Assent by June 21.

C-97 (2019 budget implementation)

And while it’s still working its way through the House committee circuit, it’s a safe bet that Finance Minister Bill Morneau’s omnibus budget bill will make it in under the wire, albeit possibly with just seconds to spare. Several Senate committees have already begun examining the contents, albeit in “pre-study” mode, which should give it a sufficient buffer to secure pre-recess sign-off by the governor-general.

Finally, it’s not a government-backed initiative, but it appears rookie Liberal MP Frank Baylis’ campaign to boost “democratic empowerment” within the House may not even make it onto the floor for an opening round of debate after Baylis failed to turn up at the appointed hour to launch the discussion.

As Huffington Post reports, he apparently didn’t realize that, on Mondays, private members’ hour takes place in the morning, and not after government business has wrapped for the day.

For his part, while Baylis admits that he’s “very upset with ‘himself’” for missing the window, he’s still hoping to get his proposal on the agenda at the House procedure committee, which could, in theory, recommend that his motion be adopted, although that could only happen if there’s unanimous support at the table to do so.
