A shooting that started at a Toronto nightclub and then spilled onto the streets outside has left at least two people dead and three others wounded.

Police say they responded to a call about shots being fired at the Muzik nightclub on the grounds of the Canada National Exhibition early on Tuesday.

The victims are a man and woman in their 20s and 30s. Three other people were taken to hospital with various injuries, Superintendent Frank Bergen said.

Police believe there could be more victims at other locations and urged citizens to contact police.

There was no immediate word on suspects or arrests, nor any information about what led to the gunfire.

The nightclub was hosting the official OVO Fest after-party featuring Toronto rapper Drake. It was not immediately clear if he was present during the shooting.
