A pole-mounted transformer exploded early in the morning and a fire broke out on the hydro pole, cutting all power to a business, Trucks Unlimited, in Steinbach, southeastern Manitoba, Canada. The business owner said the lights went out suddenly and staff reported that the transformer had blown and the pole was on fire. Manitoba Hydro was called and crews were reported to have arrived within about fifteen minutes and brought the situation under control.
