The motion was passed 35 to 5 on Thursday.
It was moved by Harinder Malhi, an MP from Brampton-Springdale district.
Malhi in her remarks said: “The Legislative Assembly of Ontario should reaffirm our values …and condemn all forms of communal violence, hatred, hostility, prejudice, racism and intolerance in India and anywhere else in the world including the 1984 genocide perpetrated against the Sikhs.”
“Today we recognise the human rights, social justice, reconciliation in the events that took place in New Delhi and other cities across India in 1984.”
The province of Ontario is “a place where people see democracy as a way to recognise the past of our neighbours and the violence that took place in 1984 which can only be described as a genocide,” the MP added.
“While we can’t change the events of 1984, we have an opportunity here today to clear the misconceptions that divide the community and the residents of Ontario.”
The motion comes ahead of Canadian Prime Minister Justin Trudeau’s expected visit to India either late this year or early next year, according to the country’s High Commissioner to India Nadir Patel.
The 1984 riots took place in the aftermath of the assassination of Prime Minister Indira Gandhi on October 31, 1984, by her two Sikh bodyguards.
