A memorandum was also handed over to members of parliament asking Government of Canada to intervene on behalf of Canadian Sikhs and impress upon India to follow a 2008 UN Resolution and abolish the death penalty, it said.
Several members of the Canadian Parliament attended the rally and joined Sikhs in demanding that India abolish the death penalty, SFJ said.
"As Canadian Sikhs we are united in our opposition to India s ongoing use of the death penalty despite ongoing international pressure including UN resolution 62-149," SFJ legal advisor Gurpatwant Singh Pannun said.
Following the Canadian tradition of respect for the sanctity of human life, Canadian Sikhs strongly oppose the use of the outdated and barbaric death penalty, he said.
The rally was organised by Sikh for Justice (SFJ), Ontario Gurudwara and Sikh Council (OGSC) and Ontario Gurudwara Committee (OGC).
The execution of Rajoana scheduled for March 31 has since been stayed by the Indian government.
