The federal government is preparing to help finance a national broadband backbone that would run coast to coast to coast across Canada, while also providing more direct international connections to Europe and Asia, as part of a wider push to build infrastructure under Canadian control.
Prime Minister Mark Carney announced the project Tuesday at the Canada Investment Summit in Toronto, framing it as “sovereign” infrastructure that would offer more direct and secure overseas connectivity. The government has not yet released details on the network’s planned route, capacity, cost, ownership structure or timeline, leaving much of the project’s architecture and commercial model still to be determined.
Airport Concessions Expected to Help Fund the Project
The federal contribution to the backbone would come as part of a broader effort by Ottawa to draw private capital into infrastructure. Carney said the government intends to offer long-term concessions for private investment in Canada’s four largest airports, while keeping the underlying assets in public ownership. Some of the proceeds from those concessions would then be reinvested into transportation projects and the broadband backbone. The government has said separately that the airport initiative could generate tens of billions of dollars.
New Tax Deduction Aims to Spur Fibre Investment
Alongside the financing plan, Ottawa is moving to reduce the tax burden associated with new fibre investment. A proposed measure, called the Productivity Mega Deduction, would let businesses immediately expense most new capital investment acquired starting September 15, including spending on fibre and other network infrastructure. Under the proposal, about two-thirds of capital investment would qualify for the deduction, compared with roughly 15% under the existing incentive it would replace.
The Department of Finance estimates the measure will cost $36 billion over five years. It projects the deduction would lower Canada’s marginal effective tax rate on new business investment from about 13% to 6.4%.
Part of a Broader Digital Sovereignty Strategy
The backbone plan builds on connectivity goals laid out in Canada’s National Artificial Intelligence Strategy, released in June. That strategy calls for diverse, high-capacity fibre and satellite connections linking infrastructure across the country, along with expanded domestic compute and cloud capacity. It states that underlying digital infrastructure should operate under Canadian control and Canadian law, rather than rely on foreign-controlled platforms that could face restrictions or be withdrawn.
The sovereignty rationale behind the project touches on both domestic resilience and international connectivity. While the AI strategy links high-capacity fibre and satellite networks to resilience against disruption, Carney’s announcement adds an international dimension by proposing more direct links toward Europe and Asia. The government has not specified whether the backbone would require new terrestrial or subsea fibre construction, make use of existing carrier networks, or combine both approaches.
For now, the announcement establishes the federal financing and tax policy framework intended to support the project, while leaving decisions about its technical design and commercial structure for later.
