Wednesday, February 15, 2017: Happy Birthday, Canadian Flag
When I take the 16X Metrobus into DC to go to work (as opposed to the Metrorail Yellow Line), I cut across the grounds of the Embassy of Canada between the stop where I alight and my workplace.
Yesterday morning, the building was festooned with flags. They were yuuuge. Very, very yuuuge. I thought it had to do with Trudeau's visit, but now I think something else was going on too.
It turns out that not only does Canada not have states, but their flag is not as old as the US flag either.
Flag Day, officially named National Flag of Canada Day (French: Jour du drapeau national du Canada), is observed annually on February 15, commemorating the inauguration of the Flag of Canada on that date in 1965. The day is marked by flying the flag, occasional public ceremonies, and educational programs in schools. It is not a public holiday, although there has been discussion about creating one.

I have a Canadian flag in my cubicle. I'll put it on a more prominent display.

Ironic political history:
---Hoping to make sure that the US never had a centralized supreme authority like the King, they gave most power to the states and severely limited the power of the central government. We have now evolved into a system where the national government can override most state power at will.
---Having seen the horror of the Civil War, Canada adopted a state with strong central government authority, yet has evolved into a system where the Provinces have much more real authority and independence than US States.
Relevant statement from Robin Williams: Canada must feel like the people living in a really nice apartment which happens to located above a meth lab.
