Ticket was booked and paid for as a united flight number on a flight that is operated by Air Canada.

In the united.com OLCI page is says that since this flight is operated by Air Canada, you need to check in with them.

On the Air-Canada OLCI page, it asks for name and confirmation number, and when I enter these in, it does not seem to find my record. Is it possible that the United PNR is different from the Air Canada PNR? Is the Air Canada confirmation number the same things as the PNR?

If anyone has been able to OLCI for a code-share flight operated by Air Canada, please tell me how you did it.
