I certainly can from DAWN Canada's perspective.
There are 12 cases that I could find, and I probably will have to look farther afield for more. The very first one was Regina v. Rosenberg, in 1998, wherein the court of appeal recognized that a same-sex partner is a legal spouse. That was successful.
Regina v. Latimer was when the Saskatchewan Court of Appeal upheld a mandatory compulsory sentence of second degree murder for Robert Latimer, who killed his handicapped daughter Tracy. That was successful.
Ferrell v. Attorney General was the constitutional challenge to Ontario's repeal of the Employment Equity Act, and that was successful.
Regina v. O'Connor was a criminal case about whether a counsellor for a victim of sexual assault must disclose all counselling records that defence lawyers wished to see. That case was intervened with at the Supreme Court of Canada and was successful.
One of the most famous cases was Eldridge v. British Columbia in British Columbia. This was a Charter of Rights and Freedoms case. British Columbia attempted to refuse to pay for medical interpreter services for deaf persons who were needing medical help. There was intervention at the Supreme Court of Canada, and it was successful. I believe that the particular woman needed a caesarean section. She was in the process of giving birth and was denied this assistance.
There was the British Columbia Government and Services Employees' Union v. the Government of the Province of British Columbia. That case concerned a physical fitness standard being applied to a female firefighter who was already performing her job, and when she didn't meet the new standard, she lost her job. That was upheld.
There was Regina v. Ewanchuk, which was the “no means no” definition of consent in sexual assault, which was successfully upheld.
I think there are two others.
