搞台證有其他護照

1. In theory, Taiwan can do that.

In practice, it depends if Taiwan knows if you are a Canadian as well.

2. Then you have to ask yourself - have you ever used your Canadian Passport for anything related to Taiwan?

If yes, then Taiwan knows. Otherwise, you should be fine.

3. In theory, no. In practice, yes (as they don't know your status as Canadian citizen).

The easiest way - using your Canadian Passport.

你自己唔講邊個知你有加拿大護照？

其實用加拿大護照去台灣無需辦入台證，並可停留 180日。
