Guess the Countrys Administrative Division - starts with O?

This is another in a series of geography questions. This one is different because there's only one country that starts with O... Oman in the Middle East. So, rather than make this too easy, this question is about a country's administrative division; think county, department, prefecture, province, shire, state, etc. This question contains several things about an administrative division within a country and the goal is to guess what that is.

Things about this country's administrative division:

* Its name starts with the letter "O"

* Its flag has red white blue green and gold colours

* It has 2 official languages

* It contains the most populous city in its country and its nation's capital city

* Ice Hockey and Curling are major sports

* It contains the largest waterfall (by volume) on its continent

* It contains the longest named street in the world

* It contains the most southerly point in its country

* It's actually named after a nearby lake

Please don't cheat by looking it up or looking at other peoples' opinions and guesses. Make your best guess.
