When DBC began, only four provinces/ territories (BC, NS, PEI, YT) were offering self-referral mammograms for women starting at age 40. DBC successfully advocated alongside medical professionals and patient advocates and in 2024/25, three additional jurisdictions (ON, NB, NL) lowered the screening age from 50 to 40. In Jan 2026, SK lowered the age to 43 and MB lowered the age to 45. MB and SK will lower the age to 40 later in 2026. Quebec is expected to lower the age to 45.  AB and NWT are expected to lower the age to 40.
