Capability profile
Telesat Lightspeed is a planned LEO satellite network for broadband connectivity, including military Ka-band service in the Arctic. Optical inter-satellite links are intended to move traffic through the constellation, with landing stations, points of presence and customer connections linking users to terrestrial or private networks. The August 2026 Arctic award expanded the planned constellation to 225 satellites.
Canada's C$2.3 billion base contract before tax with Telesat LEO ULC covers military Ka-band service from 65 to 90 degrees north, scheduled for 2028. Two optional five-year periods are valued at C$214 million and C$218 million. Telesat states that the 500 MHz Mil-Ka addition replaces an equivalent amount of commercial Ka-band user-link spectrum while leaving gateway spectrum unchanged. The separate MDA-led UHF/X-band procurement and a further end-to-end Mil-Ka integration agreement should not be folded into this base service award.
A usable mission connection will depend on the terminal, network access path and supporting ground integration. Telesat publishes a terminal ecosystem and has used LEO 3 for demonstrations and terminal testing; individual products remain at different certification and integration stages. The September 2026 Cailabs collaboration concerns optical-connectivity studies and demonstrations, while the Kongsberg letter of intent concerns evaluating Lightspeed within defence platforms and architectures. These are development pathways around the planned network, with configuration-specific acceptance still ahead.
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Contracted network development with a government-confirmed Arctic service award and planned 2028 service. Terminal demonstrations, product certification and end-to-end mission acceptance have distinct scopes; the complete 225-satellite service is not yet operational.
Arctic Mil-Ka service is contracted for a planned 2028 start. The base service, two optional extensions and terminal, ground-system and training integration have separate commercial scopes. Current GEO service availability should not be transferred to Lightspeed.
A technology readiness level is not established by the reviewed public sources.
Secure high-latitude connectivity can move sensor, command, and operational information across Arctic missions where terrestrial communications are limited.
Telesat Lightspeed secure Arctic connectivity may help teams working on Future submarine operational capability by contributing to maritime and undersea operations, Arctic and northern operations, and detection and situational awareness.

Canada awarded Telesat LEO ULC an initial C$2.3 billion before-tax Mil-Ka LEO service contract, with options of approximately C$214 million and C$218 million. It adds 69 MDA-built satellites to the 156 already planned/in production, producing a 225-satellite network. The separate MEO UHF/X-band component remains an MDA-led negotiation with Telesat as subcontractor, not the same executed award.

Telesat's planned network can interconnect through Telesat points of presence or customer-private infrastructure. Its supplier-defined private access and landing-station options differ by capacity and antenna/site configuration. The architecture allows customers to bring traffic into their own network; the public description does not replace an agreed site design, spectrum authorization, security requirement or service-level commitment.
