Canada vs US: where the titles actually went
Championships won by Canadian franchises versus the league-wide total, per league, since each league's first Canadian entry — computed by dividing a sourced Canadian-franchise championship count by a sourced league-wide champion-year count over the same window. The league-wide totals account for genuine no-champion years (the 1919 Stanley Cup Final, cancelled by the influenza pandemic; the 2004-05 NHL season, cancelled by the lockout; the 1994 World Series, cancelled by the players' strike) rather than treating every calendar year as a champion-year. The CFL is excluded as not applicable: it has no US franchises to compare against. Two MLS windows are shown — since Toronto FC's first MLS season (2007) and since MLS's own founding (1996) — because 'Canadian share of MLS titles' reads differently depending which start point you pick, and we'd rather show both than imply a single framing is the only honest one.

| League | Window | Canadian-franchise titles | League-wide champion-years | Canadian share (computed) | Notes |
|---|---|---|---|---|---|
| NHL | 1918–2025 (NHL era; excludes the pre-NHL 1916 Canadiens title) | 42 | 106 | 39.6% | 106 = 108 calendar years minus the 1919 Final (cancelled, influenza) and the 2004-05 season (cancelled, lockout). The 42 Canadian titles span 4 of the 7 current Canadian franchises (Leafs 13, Canadiens 23 within this window, Oilers 5, Flames 1); Canucks, Jets and Senators have 0. |
| MLB | 1977–2025 (since the Blue Jays' 1977 expansion) | 2 | 48 | 4.2% | 48 = 49 calendar years minus the 1994 World Series (cancelled outright by the players' strike). All 2 Canadian titles are the Blue Jays' back-to-back 1992-1993 wins — Canada's only MLB franchise. |
| NBA | 1995–2025 (since the Raptors' 1995 expansion) | 1 | 31 | 3.2% | No missing champion-years in this window (lockout-shortened 1999 and 2012 seasons, and the 2020 bubble, all still produced a champion). The Raptors' 2019 title is Canada's only NBA championship. |
| MLS | 2007–2025 (since Toronto FC's first MLS season) | 1 | 19 | 5.3% | Toronto FC's 2017 MLS Cup (part of a domestic treble) is the only Canadian MLS Cup in this window. Vancouver Whitecaps FC and CF Montréal, Canada's other two MLS clubs, have 0. |
| MLS | 1996–2025 (full MLS history, alternate window) | 1 | 30 | 3.3% | Same single Canadian title (Toronto FC, 2017) measured against MLS's full 30-year history rather than just the post-2007 window when a Canadian club existed. |
| CFL | Not applicable | — | — | — | The CFL has no US-based franchises (aside from a brief, now-defunct 1990s American-expansion era) — there is no meaningful 'Canada vs US' split to compute for this league. |
