Advocates of assisted suicide in Canada believe they may be close to a breakthrough in a Supreme Court case being heard in British Columbia.
Gloria Taylor, 63, who has a terminal neurological disease, is fighting for her right to decide how and when she will die. She has Lou Gehrig's Disease.

At the same time a study commissioned by Royal Society in Canada has called for euthanasia and assisted suicide to be decriminalised.
However, the ABC reports there is little appetite for the issue in Toronto.
