ELI5: Why Canada remains a Commonwealth country of the British Empire?

As a Canadian, I understand the countries history.. But why in this day is it still linked at all to Britain in the way it is?
gpt
We were British colonies that formed a country that was mostly autonomous from Britain in 1867. Over time we've gradually gained more and more independence to the point where our connection to Britain is entirely ceremonial. We happen to share a head of state.

Why do we still do things this way? It's a combination of tradition, people not really caring enough to want to go to the hassle of changing it, and the monumental (if not impossible) job of totally restructuring the constitution and the way our government is structured to change it.

Ultimately, why bother changing it?
