New homeowner - City Services and Requirements

I am in my early 30s and recently closed on a condo in a building in Ottawa, which is my first property ownership. I have correspondence with the condo management company about things related to the condo, but I have no idea where to start with things related to the city.

Where/when/how do I pay my property taxes? What is the vacant unit tax? Is there anything else required of me?

Given that my condo fees pay for water and garbage disposal I would imagine that is covered, but is there anything else I am missing? I have done the move out and in with Hydro Ottawa.
