Here it is: The moment Bill C-45 - better known as the Cannabis Act - became law in Canada.

On Thursday, June 21, the bill passed its final hurdle, as it received Royal Assent. What's Royal Assent, you ask? We'll let the website for Canada's Senate take it from here:

Royal Assent is the approval by the Sovereign of a bill that has passed both houses of Parliament in identical form. It is the process by which a bill becomes an act of Parliament and part of the law of Canada. 

Basically, it's a hallmark of Canada being part of the Commonwealth. The sovereign in question would be Queen Elizabeth II, but in modern times the responsibility falls on her representative, the Governor General, Julie Payette (that's her sitting on the throne in the video below). Realistically, it's only a formality - a rubber stamp applied to a bill that has passed both chambers of Parliament. But for all the ceremony and decorum, you're watching Canada's laws change, drastically. Check it out:
