CBC News -- Jan 09, 2017: Police dispatched bomb squad in November after pilot found what was described as an 'old radio battery'

A Sunwing Airlines pilot's "misunderstanding" set off a massive emergency response to a bomb threat near Pearson International Airport that forced the evacuation of two buildings and the dispatch of Toronto police's Chemical, Biological, Radiological, Nuclear, and Explosive Unit — an elite team that responds to suspected acts of terrorism.

Shortly after 9 a.m. on Sunday, Nov. 13, 2016, Toronto police received an emergency call after a Sunwing pilot discovered what he feared might be some sort of explosive device stuffed into his internal company mailbox.

When CBC Toronto called Sunwing about the incident, an employee who would only identify himself as Matthew described the device as "an antique radio battery." He said it was left for the pilot by one of his colleagues in what another employee described as a "joke."

The unidentified employee said the pilot thought "it would be cool" to put the battery in a colleague's mailbox.
