The airline that saw one of its aircrafts crash near Thompson 2 months ago, has been suspended.

Sources say Keystone Air Service is temporarily grounded by Transport Canada  to protect public safety.

An unnamed Transport Canada source says the federal agency suspended the airline’s air operator certificate after they found serious deficiencies.

This is the third time the airline has been grounded.
