What happens if Canada joins the European Union

UK isn’t part of EU anymore.
Sounds like they want to be again and its probably more realistic than Canada.
Is this something that can happen within the next decade? How long would it actually take to get back into the EU/would they accept them?
There are ongoing talks to accept them back in with a clause that would punish them for leaving again within the next X years. I dont see why it would take very long IF they decide to take them.
