Bill C-39 has been dubbed the most consequential economic legislation in this Parliament by the Liberal government. The nearly 240-page bill is intended to speed up the regulatory process for the approval of major projects and make changes to collective bargaining for federally regulated workers.

The bill has amassed critics, including unions, environmentalists and First Nations.

The legislation also clarifies Cabinet’s use of Section 107 of the labour code, by giving the labour minister “guardrails” on when they can intervene to end a lockout or strike, including a special mediator report and a national interest test.

Section 107 has been used by the Liberal government to end strikes and work stoppages at ports, railways, Canada Post and airlines. It is currently facing court challenges for its use.

Jobs Minister Patty Hajdu said the bill protects and strengthens workers’ right to strike, rather than weakening it. She has also said the legislation ensures that Section 107 cannot be used pre-emptively.

However, union leaders’ testimonies in front of the Bill C-39 legislative committee, argue that the bill allows the government to legitimize its use of a section in the labour code it has no business using in the first place.

Meanwhile, business and industry groups have applauded the bill’s changes to Section 107 of the code and bargaining, which they believe will help curb the amount of work stoppages that have a significant impact on Canadian supply chains and the economy.

Bill C-39 was passed at second reading, with help from the Conservative Party. However, Conservative Leader Pierre Poilievre has promised his party will make amendments “to protect the rights of workers.”
