The widow of Dr. Donald Low, an infectious disease specialist who guided Toronto through the 2003 SARS crisis, says she supports the "right to die with dignity."
Maureen Taylor's comments come as the Supreme Court is set to begin hearing a case on the issue in October.
Low, who died from a brain tumour in September 2013, made headlines with a video in which he made impassioned arguments in favour of legalizing doctor-assisted suicide.
Low's wife says the current laws, which make doctor-assisted suicide illegal in Canada, are unconstitutional.
She says her husband wanted the right to die on his own terms.
Taylor says she continues to face her grief in public out of love for her late husband, and because Low's voice commands respect in the Canadian medical community.
