Canada’s unions prepare for nationwide fight over Ottawa’s labour law proposals

Oct 29, 2026 | 11:47 AM

OTTAWA — Canadian labour leaders are warning that unions could trigger a nationwide job action if Ottawa rams through a contentious suite of proposed changes to the Canada Labour Code.

The Liberal government’s Bill C-39 includes language that would clarify a minister’s power to use Section 107 of the labour code to order a business under federal jurisdiction to resume operations, or put parties into binding arbitration.

The government has to go through a series of steps before that point, including determining that the work stoppage is affecting the national interest.

The federal government argues the changes would impose conditions on the use of Section 107 and restrict a minister’s ability to intervene.

Union leaders argue that spelling out a minister’s power to quash a work stoppage amounts to an attack on the right to strike that would weaken workers’ bargaining power.

Canadian Labour Congress president Bea Bruske said Thursday that Canada’s unions are setting up a “war room” to mount a joint defence if Ottawa uses the proposed powers to force workers off the picket line.

Unions could share funds, legal expertise and other resources to support an affected local organization.

“If this bill moves forward without amendments that protect the right to strike, no union facing government intervention will be left to fight on its own,” Bruske said.

Asked whether that collective response could lead to a general strike, Bruske said the decision to strike — or to defy a government order — is up to the local union membership.

“The rest of the labour movement has said we will step up in every single way that you need us to, whether it’s resources, whether it is financial, whether its taking actions. And it could cumulate to a day of action, 100 per cent it could cumulate to that,” she said.

Bruske made those comments flanked by dozens of union leaders at a Canadian Labour Congress summit in Ottawa on Thursday.

The federal government is proposing changes to the labour code as part of a broader piece of legislation that looks to streamline project approvals and offer more certainty to businesses and investors.

Bruske warned Thursday that the government is risking deeper labour acrimony, rather than industrial peace, in its approach to collective bargaining. Years spent fighting unions in court won’t help secure Prime Minister Mark Carney’s aggressive infrastructure agenda, she suggested.

Jobs Minister Patty Hajdu defended Bill C-39 last week at a special committee struck to study the legislation.

Hajdu argued the bill strengthens the right to strike by removing the ability to use Section 107 before a labour disruption. She said the government has a responsibility to act during an “exceptionally consequential” dispute.

“Protecting workers and protecting the national interest go hand in hand,” Hajdu said.

The Canadian Labour Congress has proposed amendments that would require a government to make its case before Parliament if it seeks to end a legal strike. The group also has proposed an independent panel of experts to assess whether an ongoing strike has created a genuine national economic emergency.

Bruske said union leaders are reaching out to MPs and senators in an attempt to get their preferred amendments on the table.

She added that while Hajdu has been receptive to labour’s concerns, she suggested other decision-makers in the Liberal government might not be open to significant changes to the legislation.

“I’m not sure that this government, in this moment, is willing to budge,” Bruske said.
