Parliament came back to Ottawa last week the way it usually does after a long summer — MPs a little sunburned, a little rusty on Question Period. And then, on the very first day back, the government dropped the biggest bill of the fall sitting on the table like a caller who’d been saving up a whole summer’s worth of news for the first minute of the show.
It’s called the Building Canada Strong Act — Bill C-39 — tabled September 21 by Prime Minister Mark Carney’s government, part of a package the Liberals bill as their answer to American tariffs and a slowing economy. The headline promise is speed: major infrastructure and natural-resource projects would get a decision within one year, instead of the years-long slog proponents have complained about for a generation. That part alone might have made for a quiet news day. Ottawa is always promising to move faster.
But tucked into the same bill is something that got the House a lot louder, a lot faster: a rewrite of how Ottawa handles strikes in the industries that keep the country’s freight moving — railways, ports, and airlines.
What actually changes for a picket line
Right now, when a labour dispute in one of those federally regulated sectors threatens to shut down a port or stop a freight train, the labour minister can reach for a tool under Section 107 of the Canada Labour Code and essentially order the dispute back to work, or refer it to the Canada Industrial Relations Board. Unions have long argued that power gets used too casually — a threat hanging over every hard bargaining table.
Bill C-39 would make that power harder to use on a whim. Before a minister could invoke it, there would need to be a finding that the dispute is genuinely harming the national interest, plus a report from a newly created special mediator sent in first to try to broker a deal. The bill also pushes bargaining earlier — sectors with a history of disruption would have to start formal talks at least six months before a contract expires — and it would require a government-facilitated “repair” process between labour and management after any stoppage. The government’s line: this preserves the right to strike while giving both sides more structure and less brinkmanship.
The unions and the opposition aren’t buying that framing. NDP Leader Avi Lewis called the bill an attack on the right to strike, a wish list handed to Canada’s biggest corporations and financial players. NDP MP Don Davies put it more bluntly on the floor of the House, accusing the government of “shoveling money at corporations” while squeezing workers. Bloc Québécois House Leader Christine Normandin said the bill doesn’t strike the right balance, calling it a dismantling of environmental safeguards dressed up as economic policy — a complaint Bloc Leader Yves-François Blanchet extended further, arguing the package is really a pitch to foreign investors built on fewer environmental and labour rules.
Why the timing landed the way it did
Here’s the thing about a bill like this — it never arrives on a blank page. As MPs argued over Section 107 in the Commons this week, forty-nine security officers at the Bank of Canada, in Ottawa and Montreal, were closing in on their hundredth day on the picket line, a dispute dragging on since late June over a contract that expired back in December 2024. The Canada Industrial Relations Board has already found, twice, that the Bank violated the Labour Code by bringing in replacement workers during the strike. On September 23, with that dispute still unresolved, Lewis stood up and accused Ottawa of breaking its own labour law in a fight involving the government’s own central bank — exactly the kind of real-world backdrop that makes a debate about “when should a minister intervene in a strike” feel less abstract to the people watching from Ottawa’s own downtown core.
It’s arriving, too, alongside a busy fall economic agenda: earlier this month Carney’s government held its first Canada Investment Summit, where officials said the event helped unlock nearly $500 billion in prospective investment. The government frames C-39 as part of the same push — faster approvals, steadier labour relations, the price of competing for capital while the country absorbs American tariffs.
Conservatives said in the bill’s first days they’d be reviewing it closely rather than staking a position, using early Question Periods mostly to press the government on affordability instead. The Commons is expected to sit through mid-December, so C-39 has months of committee hearings and amendments ahead of it — and almost certainly more picket-line headlines — before anyone knows what the final law does to the next contract fight on a rail line or a loading dock.
For now, what’s true is this: the government has put a bill on the table touching the right to strike in some of the country’s most consequential industries, unions and two opposition parties call it a step backward, and the debate is unfolding next to an actual, unresolved strike involving the government’s own institutions. That’s not a story that resolves by Friday. It’s one worth watching all the way to committee.
