On July 3, 2025, several Canadian airports experienced early morning bomb threats, resulting in evacuations and disrupted operations. The affected airports included those in Ottawa, Montreal, Edmonton, Winnipeg, Calgary, and Vancouver.

The threats were reported to Canada's air traffic control service, Nav Canada. The Vancouver airport's control tower was specifically mentioned as being threatened, prompting an evacuation and search by the RCMP, which ultimately found the threat to be false. The U.S. Federal Aviation Administration reported ground stops at the Montreal and Ottawa airports, which were lifted around 7:40 a.m. local time.

Nav Canada advised that service was resuming after the evacuations and threat assessments, but some delays could be expected. Transport Canada was also involved in assessing the situation alongside airport authorities and local law enforcement. The Ottawa airport, which experienced a "security incident," was working to return to normal operations by 10 a.m., with only a "small impact" on operations. Passengers like Austin De St. Croix and Lorraine Sundholn faced cancellations and delays.

By the time of the article's publication, the Vancouver and Montreal airports had fully resumed operations. The public was advised to check the status of their flights before heading to the airport. The incidents highlight the ongoing importance of airport security and the collaboration between various agencies to maintain public safety.
