Six Moncton residents were temporarily displaced Wednesday night after a water line break inside a downtown building containing three apartments.
The Canadian Red Cross says the two-storey Pine Street home received flood damage and there was concern over electrical safety.
Volunteers say they arranged emergency lodging and meals for a family of three from one unit, an adult couple from the second and one man from the third.
The Red Cross expects residents can return to their homes within a day or two following cleanup, repairs and a safety inspection.
