Background
Canada’s major telecommunications carriers — Telus, Rogers, Quebecor/Videotron — are rolling out fifth-generation (5G) mobile wireless networks, a technology the CRTC described in 2019 as a “major transformation” in Canadian telecommunications. Unlike earlier networks that relied on roughly 13,000 large cell antenna towers nationwide, 5G depends on low-powered small cell antennas mounted on everyday urban structures such as telephone poles, lamp posts, bus shelters, and buildings. Because so many of those structures sit on municipally owned public property, complete 5G coverage will require carriers to secure access to between 250,000 and 300,000 sites across Canada.
Sections 43 and 44 of the Telecommunications Act, S.C. 1993, c. 38 — collectively called the “access regime” — give carriers a qualified right to enter public property to construct, maintain, and operate their “transmission lines,” and empower the CRTC to set binding terms of access whenever a carrier cannot negotiate consent from the relevant public authority on acceptable terms. In 2019 the CRTC opened a broad consultation on mobile wireless deployment and squarely raised whether the access regime extended to 5G small cell antennas. After receiving submissions, the CRTC concluded in Telecom Regulatory Policy CRTC 2021-130 that “transmission line” means wireline infrastructure only and that it therefore lacked jurisdiction to adjudicate disputes over 5G antenna siting on public land. The Federal Court of Appeal unanimously affirmed that interpretation in 2023 FCA 79.
The carriers appealed to the Supreme Court of Canada, arguing that “transmission line” should be read dynamically and with technological neutrality to encompass 5G small cells, which are hard-wired into carriers’ existing fibre and cable transport networks even though they also emit wireless radio signals. The Federation of Canadian Municipalities and other respondents defended the narrower reading, emphasizing municipalities’ legitimate interests in controlling what goes on their infrastructure and in their communities.
The Court’s Holding
A seven-justice majority (Moreau J., writing for Wagner C.J. and Karakatsanis, Rowe, Kasirer, Jamal and O’Bonsawin JJ.) dismissed the appeal, confirming that the CRTC correctly held it has no jurisdiction under the access regime to resolve disputes over carrier access to 5G small cell antennas on public property. Applying the modern approach to statutory interpretation — text, context, and purpose — the majority concluded that “transmission line” carries a strong physical and linear connotation naturally suited to wires and cables but not to antennas, which transmit intelligence via electromagnetic waves radiating outward in multiple directions without any artificial guide or defined pathway. An antenna, the majority reasoned, cannot ordinarily be described as a transmission line even though it must be attached to one.
The majority drew additional support from the immediate statutory context: s. 43 contemplates entering on and breaking up land, burying infrastructure, and altering a “route” — physical acts incompatible with mounting an antenna on an existing pole. Parliament also used the separately defined term “transmission facility” — which expressly includes wireless infrastructure — elsewhere in the Act (s. 16), demonstrating that it knew how to capture wireless equipment when it chose to. The legislative history of the Act confirmed that the access regime was designed for wireline equipment, and the Radiocommunication Act‘s distinct scheme giving the Minister of Industry site-approval authority over antenna systems reflects Parliament’s deliberate decision to keep antenna siting in a different regulatory lane, sensitive to aesthetic and community-safety concerns. Broad policy objectives in s. 7 of the Act cannot on their own override that clear textual and contextual limit. If Parliament wishes to extend the access regime to 5G antennas, it must do so by legislation.
Justices Côté and Martin dissented. In their view, “transmission line” properly encompasses 5G small cells because those devices are hard-wired into existing transmission lines and function as an integrated component of a carrier’s wireline transport network. The dissent further argued that dynamic interpretation and Parliament’s commitment to technological neutrality — reflected in the Act’s broad, undefined use of “transmission line” — support treating 5G and wireline infrastructure the same way, and that the Radiocommunication Act‘s site-approval regime operates sequentially and compatibly with the CRTC access regime rather than displacing it.
Key Takeaways
- The CRTC’s access regime under ss. 43–44 of the Telecommunications Act applies only to wireline infrastructure (wires, cables, fibre-optic lines); 5G small cell antennas on public property fall outside its scope, leaving carriers and municipalities to negotiate access in good faith without a CRTC backstop.
- Dynamic interpretation and technological neutrality are legitimate tools of statutory construction, but they cannot stretch a term past its ordinary meaning and contextual limits — where Parliament used “transmission line” rather than the broader defined term “transmission facility,” that choice controls.
- General telecommunications policy objectives (orderly development, affordability, competitiveness) cannot, on their own, confer jurisdiction on the CRTC over a specific matter not covered by the statutory text; jurisdiction must be grounded in the provision itself.
- Carriers seeking legislative relief — a CRTC arbitration right for 5G antenna access disputes — must look to Parliament, not the courts or the regulator.
Why It Matters
The decision has immediate and concrete consequences for Canada’s 5G buildout. Without access to the CRTC’s dispute-resolution backstop, carriers deploying the estimated 250,000–300,000 small cell antennas needed for nationwide 5G coverage must negotiate site-by-site with thousands of municipalities and other public authorities. Where those negotiations stall, carriers have no federal regulatory forum to compel access or set terms. Critics warn this could slow deployment, raise costs, and fragment a national network project that carriers spent over $11 billion in spectrum auction fees to launch.
Beyond 5G, the ruling is a significant statement on the limits of dynamic statutory interpretation in the technology context. The majority’s analysis — that “dynamic” reading operates within, not beyond, textual and contextual constraints — will inform how regulators and courts approach future disputes about whether legacy statutes cover new technologies. It also reinforces the primacy of inter-statute coherence: where Parliament has created a parallel regulatory scheme (here, the Radiocommunication Act‘s antenna-siting process) that reflects distinct policy judgments, courts will treat that as a deliberate allocation of authority rather than a gap to be filled by the older statute.
