I / We / You have gone to Canada already.

[Alice Chu]

Hello, dear teachers.

1. I / We / You have gone to Canada already.

I think the sentence above is incorrect because “gone” means a completed action. If I, we, or you have left for Canada, we wouldn’t be talking here.
I would use “been” in place of “gone” to mean a life experience. However, I’m not a native speaker, so I can’t be sure if my understanding is correct. In order to teach my students correctly, I have been trying hard to understand grammar well, but I’m still confused.
Could you please help me with my problems?
Thank you very much.

They are unnatural in BrE. They would all use "been" in place of "gone".

Look at the difference between these two dialogues:

Helen: Shall we go to Canada on holiday next year?
Sarah: I've already been to Canada. How about New Zealand?
Helen: I've already been there!! We'll have to find somewhere neither of us has been.

John: Hi, Sarah. Is Peter there?
Sarah: No, sorry, he's out.
John: Oh, we were meant to be going shopping together.
Sarah: That's strange. He's gone to the shops already.
John: Never mind! He obviously couldn't wait for me.
