Air North flight ANT352, an ATR 42-300, was en route when the flight crew observed a low oil pressure alert for the no. 2 engine (PW121). The checklist was followed, resulting in shutting down the engine and restarting it. Shortly after starting the no.2 engine a CCAS alert sounded, requiring the engine to be shut down again. An emergency was declared and the flight continued to CYXY without any further issues. The flight crew conducted a single-engine approach and landing with no issues.
Following the flight, the maintenance team replaced the no.2 oil cooler and associated filters. The aircraft was returned to service.
