You were right.
UPDATE:
We received a message from the embassy stating that anyone who may have a claim to Canadian Citizenship is not eligible for a Temporary Resident Visa. As a result, the TRV application will be withdrawn.
They also advised that I must first obtain a Canadian travel document such as a Passport, which requires an application for a document of proof of Canadian citizenship.
I already applied for the Canadian Citizenship Certificate more than a year ago and there is no movement on the application thus far.
