The fire broke out in the CN Towers Toronto at 4 a.m. in an area located above the structure’s observations deck.
Seven fire trucks and 28 firefighters are on the scene, including members of the technical rescue team, Toronto Fire District Chief Stephan Powell added
“This is the main antenna mast,” Powell said. ”It is the highest point on the tower.”Powell said there was a “tar-like substance” that appeared to be “dripping” off the tower this morning.
“There are numerous wires that run up there. They have been de-energized. It is still smoldering and we’ve got crews on scene,” Powell added.
The confined space where the fire broke out is difficult to access.
“It is physically very demanding. It is something we do train for because it is a very unique building in the city of Toronto,” Powell noted.
The cause of the fire is not yet known but Powell said it may be “of an electrical nature.”
All cleaning staff and others have been evacuated from the building by the crew, the situation is under control.
Neil Jones, Chief Operating Officer for the CN Tower, said there is no threat to public safety or the structure.
“Once the chief gives us the all clear, then we operate as normal but we have to make sure everything is under control and safe,” he added.
“I think most stuff we relay to other sites,” he said. “Also, our broadcast communications experts are on site as well and they are upstairs with Toronto Fire.”
Some broadcasters took to social media on Wednesday morning to report issues with transmission.
Toronto Fire Services also confirmed the broadcasting issues in a tweet.
