Thank you for the clarification.
With regard to the ETA, the electronic travel authorization, it is a means for visa-exempt clients to confirm for entry. However, it doesn't have the same eligibility requirements as the temporary resident program.
Clients who are applying under the temporary resident program need to demonstrate the bona fides for their visit, as well as providing the other required documentation. ETA clients are exclusively required to register, such that we have information on who is entering the country.
The two are not comparable from a program design perspective.
