Flooding has forced St. Joseph's hospital emergency department to close temporarily.

A water pipe malfunctioned at St. Joe’s Charlton campus Wednesday morning and caused “significant flooding,” according to a statement from the hospital. No patients or staff were harmed in the flood, the statement reads.

Officials can’t yet say definitely if the flooding is due to the frigid temperatures Hamilton has suffered through over the last couple of days.

All outpatient visits, elective surgeries and appointments at the Charlton Campus at 50 Charlton Avenue East have been cancelled for Wednesday in all buildings except the Fontbonne Building. All dialysis appointments are still happening and on schedule.

The water pipe has stopped emitting water and damage is now being assessed and contained, officials say. Hamilton EMS units are diverting patients to other Hamilton hospitals as needed throughout the day.

“We will continue to update on our community here as the situation changes throughout the day,” the statement reads.

Parts of the Juravinski Cancer Centre are also closed on Wednesday because of flooding in some parts of the building. Chemotherapy and radiation appointments have been cancelled. The cancer centre will contact patients scheduled to have treatments on Wednesday, the centre said in a media release.
