TECO would be the wrong people to ask this question
As for the other part, example if you didn't enter Taiwan using a Canadian Passport hence accessing the 90-days tourist visa, your EXIT visa is now part of your Taiwanese passport and those can be revoked.
As a Canadian tourist it makes sense to use your Canadian passport. If you're working or studying in Taiwan then it may be a different story
