According to centre officials, said the attack occurred around 8 pm, when dozens of people were gathered in the mosque.
The Quebec City Police later confirmed that two people were arrested in connection with the attack.
Canadian Prime Minister Justin Trudeau condemned the attack and said, “Tonight, Canadians grieve for those killed in a cowardly attack on a mosque in Quebec city. My thoughts are with victims and their families.”
The mosque previously experienced acts of vandalism and xenophobic messages.
Last June, during the month of Ramadan, someone left a pig’s head with a note saying “Bon Appetit” on the door of the mosque.
