Verdict: Mixed · Confidence: High · Status: Stable · Last reviewed: September 14, 2026 Original source: Origin unclear · This card combines two related Postmedia ownership and concentration claims.
The answer
The 80% claim is false, but the U.S.-ownership claim is substantially true. News Media Canada lists Postmedia with 36 of Canada's 66 daily newspaper titles in 2025—about 55%—and 82 of 750 community-newspaper editions. Separately, Postmedia's own filings reported that U.S.-based Chatham Asset Management and related funds owned about 63% of its shares as of May 31, 2025, while holding about 31% of voting rights.
Claim | Finding |
Postmedia owns more than 80% of Canada's newspapers | False |
Postmedia owns a majority of Canadian daily newspaper titles | True — 36 of 66 in 2025 |
U.S.-based Chatham Asset Management and related funds own a majority of Postmedia shares | True — about 63% as of May 31, 2025 |
Chatham controls 63% of Postmedia's voting rights | False — reported voting rights were about 31% |
Where did this claim come from?
Origin status: Unclear.
This public card combines two related but distinct claim strands: an exaggerated claim about Postmedia's share of Canadian newspapers and a supported claim about U.S.-based Chatham Asset Management's majority equity ownership of Postmedia. Because the merged formulation has no single originating artifact, provenance is marked Origin unclear. Representative primary appearances and authoritative verification sources for both strands are preserved in the Evidence trail.
What actually happened?
Postmedia has substantial reach in Canadian newspapers. It owns more than half of Canada's daily newspaper titles and can be especially dominant in particular local markets. Its ownership structure is also a legitimate transparency issue: Postmedia's own May 2025 filing reported that U.S.-based Chatham Asset Management and related funds held a majority of the company's equity. Concerns about concentration and foreign financial ownership therefore have a real factual basis.
Two different measures are often collapsed together. Postmedia's large presence in Canadian newspapers does not mean it owns more than 80% of all Canadian newspaper titles; current national title counts are well below that figure. And majority equity ownership by Chatham does not mean Chatham holds an equivalent share of voting control: the same filing reported about 63% of shares but about 31% of voting rights. Newspaper-title share, local market concentration, equity ownership and voting power are different metrics.
Why you're seeing this claim
This claim combines two real concerns—media concentration and foreign ownership—into a stronger numerical assertion. It can benefit critics of corporate media power and advocates of ownership restrictions, but the policy relevance of those concerns does not validate an inaccurate denominator. The tracker has not identified a single origin, and the number may spread because concentration is genuinely high even though 80% overstates it.
The key distinction
Postmedia is one of Canada's largest newspaper companies, but current industry title counts do not support the claim that it owns more than 80% of Canadian newspapers. News Media Canada lists Postmedia with 36 of 66 daily newspaper titles in 2025, about 55%, and 82 of 750 community-newspaper editions, about 11%. Separately, Postmedia's own financial statements reported that U.S.-based Chatham Asset Management and related funds owned approximately 63% of Postmedia shares and about 31% of outstanding voting rights as of May 31, 2025. High market concentration and majority foreign equity ownership are therefore both legitimate issues, but they are not the same claim.
What remains uncertain
Both market-share and corporate-ownership figures can change. Newspaper closures, acquisitions and reclassifications can alter Postmedia's share of daily or community titles, while later corporate filings can change the reported Chatham equity and voting percentages. Different concentration measures—titles, circulation, audience, revenue or local-market share—can also produce different results.
What would change our conclusion
New News Media Canada data showing Postmedia above 80% under a clearly defined national newspaper measure would change the first finding. A newer Postmedia filing showing Chatham and related funds below 50% of outstanding shares would change the majority-equity-ownership finding.
Why it matters to Canadians
Canadian media concentration and foreign ownership are legitimate public-interest questions. Combining these claims makes the distinction clearer: Postmedia is highly influential and majority U.S.-owned by equity in the cited filing, but that does not make the separate claim that it owns more than 80% of Canada's newspapers accurate.
