LONDON, ONT. -- It's a simple gesture of thanks in these uncertain times.

Emergency services personnel in London formed a convoy on Wednesday to show the community's appreciation for health care workers and support staff at local hospitals.

Sirens were blaring and lights flashing as the convoy passed University Hospital late in the morning - as a sign of gratitude for those keeping the community safe and healthy.

Officials with the London Police Service, London Fire Department and the Middlesex-London Paramedic Service took part in the parade.

After circling University Hospital, it then made its way down Richmond Street to St. Joseph's Health Care

There was a second round that started at London Health Sciences Centre's Victoria Campus at 2 p.m. and continued across Commissioners Road to Parkwood Hospital.

The convoy circled all four facilities for staff and patients to catch a glimpse.
