About 30 residents were evacuated overnight from their long-term care home outside London after the sprinkler system broke and caused flooding.

Oxford County Public Health says a sprinkler valve at the Woodingford Lodge in Tillsonburg failed Friday night, resulting in a flood and water damage.

Spokeswoman Tommasina Conte says the last of the 32 residents were transferred to other health care facilities by Saturday morning.

She says families will be contacted directly with updates and that officials are assessing the damage.
