Even if going to a country the requires Canadians to have a visa, I leave my Canadian passport in the file, but when the agent checks for entry eligibility at destination, I show the second passport. Which actually is not entered in the file, I believe.
Just reporting what I have done, multiple times have checked in only with my Australian being presented, except when transiting the US of course. Only my Canadian is on file - very good chance check in agent reviews and sees Canadian on there anyway.
