Hospitals and CLSCs in the Lanaudière region cancelled a series of medical services Wednesday because of a computer problem.

Pierre-Le Gardeur Hospital cancelled all surgeries, as well as appointments for x-rays, CT scans and other imaging services.

The CLSC Meilleur and CLSC Lamater both suspended their blood tests and other testing services for the day, as well.

The CSSS in the southern Lanaudière region said it was working intensively to return operations to normal.

It is asking people who need non-urgent medical attention to call Info-Santé at 811 or to use nearby medical clinics or family medicine groups.
