C-GORN, a Beech 1900D aircraft operated by Air Georgian, was conducting flight GGN7277 from  Harrisburg Intl, PA (KMDT) to Toronto/Lester B. Pearson Intl, ON (CYYZ). During the flight, the  flight crew noticed an acrid smell in the cockpit. As there was smoke associated with the smell, the  flight crew donned their oxygen masks, advised the passengers of the situation and requested  priority landing. Shortly after, the flight crew noticed that COMM1 was unserviceable. The aircraft  landed uneventfully at CYYZ with ARFF standing by.
The operator’s maintenance confirmed the smell was from the COMM1 control head and  proceeded to replace it. The aircraft was then returned to service.
