Emergency crews from across the region will be taking part in a mass casualty exercise tomorrow.

Courtenay Fire Chief Don Bardonnex says crews from across the Comox Valley will be taking part. He says volunteers will be dressed up as emergency scenario victims.

Bardonnex says they know that at some point there will be an incident that will require all the departments in the Valley to work together, so it’s important the crews get the opportunity to also do some training together.
