Telesat Corporation (TSX: TSAT) said on August 4, 2026 that its subsidiary Telesat LEO ULC has signed a $2.3 billion services contract with Canada’s Defence Investment Agency to deliver secure Military Ka-band Arctic connectivity to the Canadian Armed Forces under the Enhanced Satellite Communications Project, Polar. The company called it the largest contract in its six-decade history. All amounts in the announcement are in Canadian dollars unless otherwise noted.
The agreement includes two five-year option periods valued at approximately $200 million each, taking the total contract value to $2.7 billion. The service period runs 15 years including the option years, with service beginning in 2028. Telesat said the expected start of Lightspeed global service delivery remains on track for Q1 2028. The company is quoted on the Nasdaq under the same TSAT symbol.
What the contract buys and what it builds
The award lets Telesat expand the Lightspeed low Earth orbit network immediately by 69 fully funded satellites, taking the initial constellation from 156 to 225 spacecraft, a 44% increase over the prior plan. The expansion will be funded through milestone-based payments from the Government of Canada starting in Q3 2026, which means the construction is funded by payments received before service revenue begins in 2028. Telesat put its total expected investment in the 225 satellite network at approximately $7 billion, with $2.7 billion invested to date.
Coverage is specified by latitude rather than by geography in general terms. Telesat will deliver Mil-Ka connectivity across Canada’s Arctic region spanning 65 to 90 degrees North. Geostationary satellites sit above the equator and serve high latitudes poorly, which is the physical reason a polar-capable low Earth orbit fleet is the vehicle for this requirement. The Mil-Ka portion of the programme also covers end-to-end network integration services including user terminals, ground and control infrastructure, training and support, all of which sit under a separate agreement between the Defence Investment Agency and Telesat rather than inside the $2.3 billion figure.
The manufacturing side was disclosed the same day by the builder. MDA Space Ltd. said it will supply additional MDA AURORA next-generation broadband satellites, raising its own order by 27 satellites over the previously announced 198 and increasing the total value of its contract by $474 million. That increment covers the new satellites, the addition of 500 MHz of military Ka-band to Lightspeed satellites already in build, replacing the same amount of commercial Ka-band spectrum, and other long-lead items. MDA said the majority of the increase will be added to backlog in the third quarter of 2026, since some long-lead-time items were booked earlier. The satellites are to be built in Montreal and launched by SpaceX on already-secured Falcon 9 rockets, with one further Falcon 9 subject to completion of a launch services agreement.
This is not a new relationship. MDA Space, the Department of National Defence and Telesat signed a strategic partnership agreement on December 9, 2025 covering military satellite communications delivery under the same programme, led by Canada’s newly formed Defence Investment Agency. The August contract converts that partnership into a priced, dated commitment for the Ka-band component. The ultra-high frequency and X-band portion of the programme remains at the negotiation stage, with MDA Space as prime contractor for end-to-end mission delivery and Telesat as a subcontractor, and contract details to be disclosed once finalised.
Dan Goldberg, Telesat’s president and chief executive officer, said in the announcement: “High speed and low latency connectivity is critical for modern military forces, and Telesat Lightspeed is expected to be foundational for future CAF and allied governments’ operations.”
The financial backdrop the award lands in
Telesat’s second quarter results, published on August 13, 2026, show why the contract matters to the company beyond the headline number. Consolidated revenue for the quarter ended June 30, 2026 was $79 million, down 25%, or $27 million, from the prior year. Adjusted EBITDA was $22 million, a decrease of 62%, or $37 million, from the second quarter of 2025; excluding higher expenses tied to the Telesat GEO debt refinancing process, the decline was 45%. The net loss for the quarter was $559 million against a $76 million gain a year earlier, driven mainly by non-cash losses on an increase in the fair value of the Lightspeed Financing Warrants and by a weaker Canadian dollar lifting the Canadian dollar value of U.S. dollar-denominated debt.
The legacy business is shrinking while the new one is being built. GEO segment revenue was $78 million in the quarter, a 26% decline of $28 million, on non-renewals of certain broadcast contracts in 2025 and lower fixed broadband services, partly offset by new aviation contracts. In the LEO segment Telesat invested $165 million in Lightspeed during the quarter, comprising $20 million of operating expense and $145 million of capital expenditure. Goldberg said Lightspeed is fully funded and pointed separately to US$189 million in incentive payments scheduled under the U.S. Federal Communications Commission’s Upper C-Band Report and Order, tied to repurposing 160 MHz of C-band spectrum for terrestrial wireless use, and to a recent US$120 million borrowing at a Telesat GEO subsidiary.
Analysis: how the award funds the build before service begins
The most consequential sentence in the announcement is not the $2.3 billion headline but the one about milestone-based payments starting in Q3 2026. Service revenue does not begin until 2028, yet the 69 additional satellites are described as fully funded from the day of signing. That sequencing means the Government of Canada is financing the build ahead of service, and it explains how a company reporting $79 million of quarterly revenue and $165 million of quarterly Lightspeed spend can add capacity of this scale without a matching capital raise being announced alongside it.
The disclosure also separates two things that are easy to conflate. The 44% increase applies to the constellation as a whole, not to the military allocation. MDA’s parallel release says every AURORA satellite in the Lightspeed build, including those already under construction, will carry 500 MHz of military Ka-band in place of an equal amount of commercial Ka-band. Military capability is therefore being layered across the fleet while total satellite count rises, so commercial capacity does not scale one for one with the 44% figure. Neither company published a split of the 225 satellite network’s capacity between defence and commercial use.
What the announcement does not establish is the economics of the contract to Telesat. There is no disclosed margin, no revenue recognition schedule and no statement of how much of the $2.3 billion is pass-through to MDA Space, whose own increment is $474 million on the manufacturing side. The integration services, terminals and ground infrastructure sit under a separate unpriced agreement. A reader working out what the award is worth would need those two documents, not this one.
The near-term checkpoints are mechanical rather than strategic. MDA said the majority of its $474 million increase enters backlog in the third quarter of 2026, so that number should be visible in its next quarterly disclosure. Telesat’s milestone payments should begin appearing in the same period. The launch services agreement for the remaining Falcon 9 is outstanding. And the UHF and X-band component of the programme, where Telesat is the subcontractor rather than the prime, has no announced value at all.
