Fire has destroyed the main building at the popular St. Jacob's Farmer's Market north of Waterloo, Ont., the Kitchener Fire Department has confirmed.


"The main two-storey building is a total loss," said spokesman Dale Martin, who said the fire department received a call around 1:48 a.m. ET for a fire at the market.


"On arrival, the farmers market building — the main building — was totally involved in fire, coming out through the roof. At that point we concentrated on the other buildings around here, where the livestock sales happen," said Martin.


Between 30 and 40 firefighters from four different stations battled the fire, according to Martin.


The cause of the fire has yet to be determined.


"It'll be a big loss for the community," said Martin.


Crews are still working to put out hot spots.
