Narrative:

Normal uneventful flight until final approach. [We were] cleared for a visual approach [and were] fully configured to land. At approximately 1;500 feet first received an amber 'left fuel lo press' caution message. It went away fairly quickly. I then noticed a white status message 'AC ess xfer.' at about the same time the first officer noticed he needed a lot of right wing down correction and asked [me] to pull up the flight control synoptic page. Shortly thereafter received a master warning 'left engine oil press' message and audible alert. We then noticed the left engine was at reduced power. N1 was approximately 39%; itt (interstage turbine temperature) approximately 850; and N2 approximately 42%. We realized the left engine was either failed or running at a very reduced power level and not responding to thrust lever movements. This was approximately at 1;000 feet now.I declared a left engine failure. First officer called for flaps 20 and increased speed to approximately vt. We elected to continue the approach. I selected ground proximity flap override. I knew the runway length was adequate at 9;500 feet long. APU had previously been started and the bleeds [had] been transferred sometime prior to the approach. First officer landed normally and I exited the runway. At this time the itt spiked to 900 and flashed red. We shut off the left thrust lever. At this point I set the parking brake and called the flight attendant. Informed him of the issue and made a public address to the passengers. At that time there were no indications of any further issues. It appeared normal; just like a single engine taxi. We reviewed the QRH to ensure everything was normal. We requested a visual inspection of the left engine to look for smoke; leaks; or damage. [We were] informed that everything appeared normal so we elected to continue taxi to the gate. Taxied to the gate uneventfully.

Title: CRJ-200 flight crew reported the left engine degraded to a low power state on short final; and was shut down after landing when the ITT spiked into the red range.
