Manitoba's utilities regulator is warning consumers to be wary of people selling residential natural gas contracts door-to-door.

The Public Utilities Board says some salespeople are approaching homeowners claiming they are representing Manitoba Hydro or Centra Gas.

The board says this isn't true.

It says such salespeople are independent agents representing natural gas marketers.

The board says if consumers believe they have been defrauded or mislead they should contact the natural gas company or the utilities board.
