Narrative:

We were en route from cvg to yul (montreal) and had just leveled off at FL330. We got a left engine oil pressure warning message and noticed that the oil pressure was dropping off rapidly. We asked and received clearance to FL240. During initial descent, we shut down #1 engine as per checklist and asked for clearance to toronto. We declared an emergency, communicated with flight attendant, and passenger, and completed our checklists. We landed without incident on runway 5 in toronto and taxied to the gate. After engine shutdown and walkaround, we noticed an oil smell and what appeared to be burning oil (small amount) from #1 engine. Prior to leaving the gate in cvg, I had asked the first officer to check the oil as is required on final outbound flight of the day per our flight standards manual. When filling out the logbook after landing, first officer informed me that he had forgotten to check the oil. In this situation, we normally replenish, check oil before leaving the aircraft for the night. I don't believe that this was related to the engine shutdown as our oil pressure had dropped to 0 psi, but mention it because it may have alerted us to an oil leak if present.

Title: CL65 CREW SHUT DOWN #1 ENG BECAUSE OF NO OIL PRESSURE IN CZYZ CLASS A AIRSPACE.

Narrative: WE WERE ENRTE FROM CVG TO YUL (MONTREAL) AND HAD JUST LEVELED OFF AT FL330. WE GOT A L ENG OIL PRESSURE WARNING MESSAGE AND NOTICED THAT THE OIL PRESSURE WAS DROPPING OFF RAPIDLY. WE ASKED AND RECEIVED CLRNC TO FL240. DURING INITIAL DSCNT, WE SHUT DOWN #1 ENG AS PER CHKLIST AND ASKED FOR CLRNC TO TORONTO. WE DECLARED AN EMER, COMMUNICATED WITH FLT ATTENDANT, AND PAX, AND COMPLETED OUR CHKLISTS. WE LANDED WITHOUT INCIDENT ON RWY 5 IN TORONTO AND TAXIED TO THE GATE. AFTER ENG SHUTDOWN AND WALKAROUND, WE NOTICED AN OIL SMELL AND WHAT APPEARED TO BE BURNING OIL (SMALL AMOUNT) FROM #1 ENG. PRIOR TO LEAVING THE GATE IN CVG, I HAD ASKED THE FO TO CHK THE OIL AS IS REQUIRED ON FINAL OUTBOUND FLT OF THE DAY PER OUR FLT STANDARDS MANUAL. WHEN FILLING OUT THE LOGBOOK AFTER LNDG, FO INFORMED ME THAT HE HAD FORGOTTEN TO CHK THE OIL. IN THIS SIT, WE NORMALLY REPLENISH, CHK OIL BEFORE LEAVING THE ACFT FOR THE NIGHT. I DON'T BELIEVE THAT THIS WAS RELATED TO THE ENG SHUTDOWN AS OUR OIL PRESSURE HAD DROPPED TO 0 PSI, BUT MENTION IT BECAUSE IT MAY HAVE ALERTED US TO AN OIL LEAK IF PRESENT.
