first of all "British Columbia" as a name sucks. there's no longer any need to be British, and Columbia comes from the river Columbia which comes from the ship Columbia which comes from Christopher Columbus and that sucks. I propose that it be renamed to Boreal Cascadia (Cascadie boréal):
- retains its initialism in both English and French
- more factually accurate (part of it is quite boreal, and part of it is in Cascadia)
- sounds cooler
the fact that a simple internet search revealed that the suggestion had already been made by dozens of other people on the internet is only evidence that it is a reasonable and suitable name
second of all if we're getting rid of the British in the name we have to get rid of the British in the flag. NO more union jack NO more crown. I propose the above flag with the following features:
- we can keep the waves. it's supposed to represent the Pacific and the Rockies and those sure are still there
- removed the ugly spokes of the sun and put it in the back bc let's be real there's hardly that much sun in BC to feature it so prominently
- added some trees which are literally the most prominent feature of the province between the ocean and the mountains like how could the original flag NOT have any trees at all (the green is stolen from Yukon's flag btw)
- (idk how to draw trees so I made them out of triangles for now. I'll go steal some trees from elsewhere later)
- the background looked empty so I made it Canada Flag Red
for the BLOOD OF OUR ENEMIES
if you follow me on Mastodon you'll have seen my thread on this. if you don't here's some of the previous iterations of the flag I had

first I just straight up got rid of the union jack and crown. simple enough

of course trees are the big thing so there has to be "trees" (triangles that look like teeth)

I guess we don't need that many triangles to get the point across. three trees is enough to mean many trees

and let's be real there isn't that much sun in BC

I still thought the triangles looked like a weird green flower so I put triangles on top of each other as trees 2

alright fine we can have a little bit of sun. but none of those ugly spokes
