Hello,
Can you please provide more detailed changeset comments instead of simply Quebec?

I see you have tagged numerous telephone exchanges (central offices) with the ref tag with the area code and CO code. While that may be relevant data to add, I don't believe it belongs in the ref tag.
The telecom industry uses CLLI codes <https://en.wikipedia.org/wiki/CLLI_code> in order to reference exact sites and exact equipment.

You seem to have tagged some buildings with `communication=yes`, can you explain what that tag is?

You also seem to have added the `area=yes` tag to some buildings. That tag is not needed as buildings are considered areas by default.

Finally, you shouldn't add `Telus Quebec` to the name tag (except for the telecommunications office), it should instead be in the operator tag.
