Quebec Muslims have conducted their morning prayers amid tight security following yesterday's mosque shooting in the city that left six dead and five in hospital.
Two people were arrested shortly after the shooting, although police say one is now a witness rather than a suspect.
Sources have told Reuters the suspect is Alexandre Bissonnette, a French-Canadian.
Doctors said three of the survivors of the shooting remained "between life and death".
All of the victims were men, shot as they prayed.
Canadian Prime Minister Justin Trudeau condemned the shooting as a terror attack on Muslims - the first of its type in the country.
Police have tightened security around mosques in both Quebec and Montreal cities but said the situation was under control.
