Tunnel found near Toronto Pan Am Games venue, police say

WATCH: Cindy Pom reports on the mysterious underground tunnel found near York University.

TORONTO – Police say a tunnel was found near a Pan Am Games venue at Toronto’s York University but it poses no known security threat “at this point.”

Const. Victor Kwong said Monday that the tunnel was found by a Toronto and Region Conservation Authority employee, who then reported it to police.

Kwong would not comment further but said Toronto police have scheduled a news conference for Tuesday morning.

Ontario Provincial Police, meanwhile, said there is currently no threat but they continue to monitor the situation.

A Toronto police source said a thorough investigation followed the discovery of the tunnel “about a month ago.”

The CBC reported the tunnel was about 2.5 metres deep and about seven metres long before it was filled in by authorities.

The broadcaster said the tunnel had lights inside and was powered by a generator.
