Canada Finally Enforces What the ITU Only Suggested
For more than two decades, the 25-year de-orbit guideline from the Inter-Agency Space Debris Coordination Committee sat on the books as a voluntary benchmark — honoured in licensing documents and largely ignored in practice. In April 2026, Innovation, Science and Economic Development Canada (ISED) closed that gap. Decision SMSE-009-26 converts the guideline into a binding licence condition: satellites in low Earth orbit must complete controlled atmospheric re-entry no later than five years after end of operational life. Alongside it, Transport Minister Steven MacKinnon announced Bill C-28 — the Canadian Space Launch Act — on April 21, 2026, creating Canada's first statutory framework for commercial launches from Canadian soil. Together, the two moves represent Canada's most significant reconfiguration of space governance in over a decade.
The Case for Strict Rules Is Solid
The strongest argument for SMSE-009-26 is not hypothetical. Low Earth orbit is congested to a degree that the 2004 IADC guidelines could not have anticipated. SpaceX's Starlink has more than 7,000 operational satellites; Amazon's Kuiper constellation is scaling up; China's state-backed Spacesail launched 200 satellites in the first five days of June 2026 alone, deliberately targeting markets where Starlink has drawn regulatory friction. Every abandoned satellite above 600 km is a permanent hazard that compounds exponentially under Kessler cascade dynamics. The 25-year window was designed for an era when a few dozen satellites shared each orbital shell; it was never calibrated for mega-constellations numbering in the thousands. Regulators who insist on binding end-of-life accountability are not being anti-innovation — they are protecting the orbital commons that all innovation depends on.
What SMSE-009-26 Actually Requires
The decision sets four interlocking conditions for LEO licensees. First, the 5-year post-mission disposal window replaces the old 25-year guideline for non-geostationary orbit systems — medium Earth orbit and highly elliptical orbit satellites remain on the legacy timeline. Second, each satellite must demonstrate a 90% or greater probability of successful post-mission disposal; constellations face a 99% aspirational standard that ISED declined to make mandatory after industry pushback. Third, satellites operating with an apogee above 600 km must carry active propulsion systems capable of collision avoidance and controlled de-orbit — a threshold ISED raised from 400 km to accommodate smaller passive missions in lower shells. Fourth, all LEO licensees must register with a Space Situational Awareness service, maintain current ephemeris data, and provide 24/7 contact points for conjunction alerts. These are not aspirational targets: compliance will be enforced as licence conditions, giving ISED the authority to revoke spectrum rights for non-compliant operators.
Canada Is Catching Up to the FCC, Not Getting Ahead of It
It is worth noting that Canada's action is not globally premature — it is four years late. The US Federal Communications Commission adopted an identical 5-year LEO de-orbit rule in September 2022, making it effective for new applications from September 2024. Canada's SMSE-009-26 brings Canadian licensing conditions into alignment with the country's largest trading partner and the jurisdiction that licenses the bulk of the world's commercial constellation satellites. That alignment matters practically: operators managing constellations under both FCC and ISED licences will no longer have to reconcile conflicting end-of-life timelines. For Starlink specifically — which already lowered its operational altitude from 550 km to 480 km on January 1, 2026, reducing natural atmospheric decay time from roughly four years to a matter of months — the new Canadian rules impose little additional operational burden.
The Small-Satellite Problem ISED Has Not Fully Solved
The harder policy question is not Starlink. It is AlbertaSat. It is the university CubeSat teams and early-stage startups that constitute Canada's emerging domestic space sector — the very constituency that Bill C-28's Spaceport Nova Scotia ambitions are supposed to cultivate. AlbertaSat estimated that active propulsion systems cost between $50,000 and $200,000 CAD and represent at least 14% of a small satellite project's total budget. For Starlink, that cost is trivially absorbed across thousands of units. For a 3U CubeSat built by a university team on a $500,000 grant, it can be prohibitive. The Canadian Bar Association's 2025 prize essay on the ISED consultation documented these concerns explicitly, recommending a tiered regulatory approach — exemptions or alternative compliance paths for satellites below 600 km that would naturally re-enter well within the 5-year window through atmospheric drag alone, without powered manoeuvres. ISED raised the propulsion threshold from 400 km to 600 km, which is a step in the right direction, but it stopped short of publishing clear alternative compliance pathways for experimental drag-sail or electrodynamic tether systems that could achieve disposal without conventional propulsion.
Space Launch Act and the Bigger Picture
Bill C-28 frames SMSE-009-26 within a larger strategic ambition. Canada remains the only G7 nation without sovereign launch authority, relying entirely on foreign providers to reach orbit. The Canadian Space Launch Act creates the statutory architecture that a domestic launch industry requires — liability protocols, operator licensing, re-entry oversight — and gives legal teeth to the $200-million Spaceport Nova Scotia infrastructure investment announced in March 2026. The government estimates the commercial space launch sector accessible to Canada could be worth $40 billion. SMSE-009-26 ensures that the satellites those future Canadian rockets put in orbit will come down on schedule.
A Rule That Works for Starlink Must Also Work for Startups
The 5-year de-orbit rule and the 90% disposal probability standard are well-calibrated. The 600 km propulsion threshold is a reasonable line. But ISED should publish a formal alternative-compliance framework — specific criteria under which drag sails, passive de-orbit devices, or low-altitude deployments can satisfy the disposal requirement without active propulsion — before the licence conditions take full effect. A debris rule that effectively grandfathers Starlink's existing fleet while imposing disproportionate costs on the small-satellite operators that Canadian space policy is trying to grow is not proportionate regulation. It is a structural advantage for incumbents dressed as environmental responsibility.
