Your birthday only comes around once a year and for many, it's one of the best days of the year! Of course, there are some birthdays that serve as special defining in a person's life such as your first, 16th, 19th, and 21st birthday. Whether it's due to a cultural norm or celebrating being legal, these defining moments are celebrated differently all over the world.

With that being said, up until the age of 21, you're not legal all over the world because of laws in the U.S. Regardless, because the legal drinking age is 19 in Canada, there are a ton of things for us to do while we wait to party over the border! Before you officially become legal globally at the age of 21, here are 21 things you must do before you turn 21 in Ottawa:
