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: 2021 24% · 2022 7% · 2023 0% · 2024 0%. Grants only. Government contracts and fees sit inside program revenue.
34% of RETHINK BREAST CANCER CANADA’s revenue is contributions — more reliant on donations than three-quarters of its peers (6% for the typical peer).

the vertical line marks half of all grant income — 4 funders to its left
100% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund RETHINK BREAST CANCER CANADA.
Largest funder’s share by year: 2017 49% · 2018 24% · 2019 23% · 2020 25% · 2021 16% · 2022 31% · 2023 40% — diversifying over time.

In-province vs out-of-province, by year
Funder regions come from each funder’s own filing. C$4k arriving through sponsors registered in 2 regions 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.
