Canadian citizens cannot apply for an eTA at all
IRCC's answer is one word long before the rule: no. Canadian citizens, including dual citizens, cannot apply for an eTA to enter Canada. You need a valid Canadian passport to board your flight to Canada. This is not a formality you can substitute — the door is closed, not narrow.

Why there is no eTA route for a citizen
IRCC explains it in the same answer: a valid Canadian passport is the only reliable and universally accepted travel document, and it proves you are a citizen with the right to enter Canada without being subjected to immigration screening. An eTA is a screening tool for foreign nationals, so it does not apply to you.

A dual citizen cannot fly in on the other passport
Asked directly whether a Canadian citizen who also holds another nationality can fly to Canada on the non-Canadian passport, IRCC answers no: Canadian citizens, including dual citizens, need to fly to Canada with a valid Canadian passport.

The rule covers transit as well as arrival
Dual Canadian citizens can no longer travel to or transit through Canada by air with a non-Canadian passport; you need a valid Canadian passport to board your flight. A connection through a Canadian airport is inside the rule, not outside it.

The official notice names the alternatives
IRCC's notice states that Canadian citizens, including dual citizens, cannot apply for an eTA or a visa and will need a valid Canadian passport, a temporary passport or an emergency travel document to fly to or transit through Canada. Those two alternatives to a full passport appear on this notice.

The exception: special authorization, if you qualify
You can apply for a special authorization that, if approved, will allow you to board your flight with your valid non-Canadian passport. IRCC lists four conditions, all of which must be met: you have not been issued a Canadian passport that is valid on the day of your travel; you have a flight to Canada that leaves in less than 10 days; you have a valid passport from a visa-exempt country or territory; and you are not a Canadian-American dual citizen.

A special authorization is good for 4 days
This authorization will be valid for only 4 days from the date of travel you select on the form. It is a boarding fix for one trip, not a standing substitute for a Canadian passport — and without the right documents, IRCC says you may be denied boarding.

Canadian-American dual citizens are the one different case
To fly to Canada, a Canadian-American dual citizen needs either a valid U.S. passport or a valid Canadian passport, and does not need a Canadian visa or an eTA when travelling on the valid U.S. passport. They are also explicitly outside the special-authorization route, because they do not need it.

Permanent residents are also not eligible to apply
The same IRCC notice states that permanent residents of Canada are also not eligible to apply for an eTA and, as usual, must show their permanent resident card or a permanent resident travel document when travelling to Canada. The eligibility page puts the other half plainly: you don't need an eTA or a visitor visa if you're a Canadian permanent resident.

What a permanent resident does need to board
Permanent residents of Canada need a valid PR card when travelling to Canada by public transit — plane, train, bus or boat. IRCC's Help Centre puts the boarding consequence next to it: you do not need an eTA, but you must travel with a valid PR card or a Permanent Resident Travel Document, or you may face delays or be prevented from boarding your flight to Canada.

If the PR card is expired or lost, abroad
If your PR card is expired or you lost it, you can apply for a PR travel document (PRTD) to travel to Canada. Without a PR card or a PRTD, IRCC says you may not be able to board your flight to Canada.
