This young child is lucky to be alive.

Toronto fire crews worked diligently for hours to free a young child who was somehow trapped in a ventilation duct.

A child was rescued from the duct on October 11 in a building on The West Mall, south of Rathburn Road.

Emergency crews were called just after 3:30 p.m. for a rescue call.

Firefighters had to disassemble the duct to free the child, who officials said did not suffer any physical injuries.

Toronto Fire Services (TFS) said the child was conscious and crying when lifted to freedom.

It is unclear how the child ended up in the duct.
