They just wanted a man cave.
Const Victor Kwong said yesterday tips from the public helped them identify the two men in their 20s responsible for building the underground chamber near a Pan Am Games venue.
News of the tunnel's discovery set off a social media frenzy, with theories of its purpose ranging from zombie hide outs to affordable housing.
Kwong said the two men just wanted to have fun and there was never any danger to public safety.
"It was a place for them to hang out. They started out as goal to make a cool place and that's what they did," Kwong said.

The bunker, discovered in January by a conservation officer in a densely wooded area, is located 25 meters from the fence of the Rexall Centre, which is to host tennis events for the Pan Am Games.
Inside, police said they found beverage containers, plywood wall supports, a generator and a sump pump. The chamber was almost 2 meters high, 34 inches wide and 10 meters long.
Toronto police announced the discovery of the tunnel on February 24 after weeks of surveillance didn't turn up anything.
Kwong said the men are not believed to be survivalists, adding they just "wanted to dig a tunnel." He said they were not ex-miners or engineers.
"The minute they were found they were apologetic," Kwong said. He said there is no connection to this summer's Pan Am Games, or to York University, which is also near the site where the tunnel was found.
