Toronto Police are investigating a shooting at the U.S. consulate, the second alleged incident targeting the building this year.

Police said in a post on X that officers heard a firearm being discharged at 4:46 a.m. on Monday in the area of the American diplomatic office, located at 360 University Ave.

Police said evidence of the shooting was found outside the consulate, and a white sedan was seen fleeing the scene. There are no suspects or reported injuries from the shooting, they wrote in the post.

On Monday morning, police officers could be seen inspecting a bullet hole on one of the building’s exterior walls and a shell casing on the ground.

University Avenue at Dundas Street was closed to vehicles and pedestrians for several hours.

Monday’s shooting marks the second time a shooting happened near the U.S. consulate this year.

Last month, police arrested and charged two men accused of shooting the building in March, tying them to a larger gun-for-hire network.

Police have alleged allege Zara Jabbi and co-accused Sheldon Tracey-Stewart stole an SUV, drove to the U.S. Consulate and shot at the building multiple times before ditching the vehicle.

Mr. Jabbi is facing six charges, including vehicle theft and attacking the “premises of Internationally Protected Persons.” An internationally protected person is a UN designation for foreign dignitaries. Canada is obliged to provide them with enhanced protection.

Mr. Tracey-Stewart is facing 11 charges, including vehicle theft, illegal firearm possession and discharging a firearm.

The allegations against them have not been tested in court.

U.S. prosecutors and the FBI have previously linked the consulate shooting to Mohammad Baqer Saad Dawood Al-Saadi, an alleged Iraqi terrorist with ties to Iran’s Islamic Revolutionary Guard Corps. He was arrested in Turkey in May and remains in U.S. custody.

Toronto police have not confirmed any connection between Mr. Al-Saadi and the attacks in the city.
