Toronto police have confirmed that a private security officer who fatally shot two men at an east-end McDonald's will not face criminal charges.

The shooting took place at a McDonald's located at 1735 Danforth Ave., just east of Coxwell Avenue, at approximately 3 a.m. on Saturday, Feb. 28.

Police said two men were involved in a physical confrontation with an armed, uniformed private security officer who had been working at a nearby location. During the altercation, the security officer discharged his firearm, injuring the other men.

Donny Ouimette, 25, and Ryan Hind, 39, were fatally wounded. The security officer was taken to hospital where he was treated for a firearm-related injury.

After a months-long investigation, Toronto police said the security officer would not be facing any charges.

"Investigators consulted Senior Crown Attorneys and provided an overview of the circumstances surrounding the deaths," police said in a statement on Wednesday.

"It was determined that there would be no reasonable prospect of conviction, therefore no criminal charges would be laid."

Following the decision, a cousin of Ouimette, Edward Cyr, said he was disappointed no charges will be laid.

"I think we are just mostly disappointed and saddened with the decision," Cyr told CP24 Wednesday evening. "There hasn't been any process for this man and I think that is where our frustration is."

According to Toronto Police Service spokesperson Mark Pugash, a review of security surveillance video footage "formed a significant part of the investigation."

Cyr said he would like that footage released to the public.

"I think until more people view that forage, we won't really know what happened."

The security guard's lawyer Craig Penney said in a statement that his client is still recovering from his injuries.

"He is grateful for the continuing support of his friends, family, co-workers, and company, and is appreciative of the professionalism of the Toronto Police Service," the statement said.

"We thank everyone for their support, patience, and understanding."
