Update:

The Portage la Prairie fire department were called to the Portage and District General Hospital around 10 p.m. Tuesday night after receiving a report of smoke and flames coming from the building's roof.

A fire department official says the source was an incinerator chimney, and there was legitimate concern among first responders, but the situation came under control fairly quickly, as the fire self-extinguished.

The fire department confirms there was a short-term lockdown at the hospital during the emergency response.
