Thunder Bay city workers spent Monday morning attempting to fix a broken water main in the city's north side.
Crews responded to water on the road in the Park Avenue and Cumberland Street area just before 8 a.m.
The water also flowed down to Water Street.
The break has created a slippery, slushy mess in the area, resulting in road closures.
Park Avenue is closed between Court Street and Water Street.
Water Street is also closed between Park Avenue and Bay Street.
The city says workers are still trying to determine where the break originated.
They have shut off water in the block bounded by Park Avenue, Red River Road, Court Street and Cumberland Street.
Thunder Bay's OLG casino is closed until further notice.
There's no word yet on how long the water will remain shut off, or how long the roads will remain closed.
