Who sounds uneducated?
Trust me, if you say to a native French speaker "Parisian French" they will understand. The French don't have the naming of dialects so wrapped up in national pride as you do. They are perfectly aware that other countries speak French. Along with that goes the need for differentiation.
As far as this Canadian is concerned, you don't need to specify "Canadian English," buy you sure as hell do have to specify "British English." You Brits speak some sort of completely barst arckwards hooey. Your "slang" is incomprehensible tripe and you've a plethora of accents and dialects that sound like someone speaking "proper" English whilst simultaneously gargling and getting strangled.
Unless you are speaking Canadian English with a northern Albertan dialect - I’ll have non ‘o that crap from the center of the universe - then you’re doing it wrong! That’s the One True Proper English, because regardless of where the language originated, we’re the ones who do it right.
See how easy it is to a right proper nationalistic ponce? Now jog on ya nationalistic barstwards…
