The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2017 29% · 2018 29% · 2019 30% · 2020 71% · 2021 64% · 2022 48% · 2023 35% · 2024 22%. Grants only. Government contracts and fees sit inside program revenue.
2% of DIEFENBUNKER CANADA'S COLD WAR MUSEUM/MUSÉE CANADIEN DE LA GUERRE FROIDE’s revenue is contributions — about as donation-reliant as the typical peer (5% for the typical peer).

In-province vs out-of-province, by year
Funder regions come from each funder’s own filing. C$20k arriving through sponsors registered in 1 region is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024 is still being filed and is shown unshaded; it does not move any figure on this page.
