This number belongs to Eagleridge Hospital in Port Moody; they are trying to assure quality post-surgery and follow up with people who have recently had surgery to find out if they had any complications after being released from the hospital.
Call is not a scam .. they are simply trying to gather data to improve their level of care.
I just had someone call from this number inquiring about my child's holiday. They then hung up after I questioned them. I called the number back and there is a recording that says it's the Fraser Health Authority and they cannot determined who called. Seems very fishy!
