Nine customs officers and two passengers at Toronto's Pearson International Airport were taken to hospital on Friday night after they were exposed to highly concentrated liquid insecticide from a passenger's luggage.

Three vials of the liquid were found to be leaking inside a passenger's checked baggage in the customs area of Terminal 3.

The officers and two passengers near the bug spray complained of burning eyes and difficulty breathing.

The victims were taken to Etobicoke General Hospital as a precaution. They didn't suffer any serious injuries.

Peel police will decide Monday if charges will be laid against the passenger whose luggage contained the insecticide. Police didn't say where the traveller had arrived from.
