Calm Air International, flight CAV111 was climbing through FL220 when the flight crew observed a Master Warning light with a CCAS 'Excess Cabin Altitude' message. The flight crew contacted ATC and requested a descent to 13,000 feet ASL. In the descent, the warning went away and the cabin pressure levels returned to normal. The flight continued to CYWG where it landed uneventfully. A subsequent inspection by the operator's maintenance revealed a jet pump needed replacement. The jet pump and 2 pneumatic outflow valves were replaced and an inspection of the electrical connections and the cabin controller wiring was conducted. Pressurization runs and operational test of the manual pressure control system were completed. A test flight was completed and the aircraft was returned to service. C-GDSS had 2 previous similar events.
