The dual citizenship thing seems to apply to people who have a Canadian passport and one from A.N.Other country. They tell you not to apply for one in this case as you should be using the Canadian one to actually enter the country.
You can also call 1-800-O-Canada according to CIC's website with eTA related questions.
