A club promoter was among the two men killed in a weekend shooting in a nightclub parking lot in the city's Port Lands.

Toronto police have not yet named the victims, telling CBC Toronto that next of kin have not been notified.

But in a statement, Ink Entertainment — which owns Rebel nightclub on Polson Street — confirmed one of the victims was an employee of the club.

"We are all deeply saddened by the tragic events of his death and would like to express our sincerest condolences to his family and friends for their loss," the statement reads.

"He was a warm and kind individual that was loved by many in the city and he will be missed."

The nightclub is working with Toronto police and will be increasing police and security presence on the street and in the parking lot, the statement continues.
