French is a terrible language which has only spread, and which only survives now, by this type of protectionism. French would certainly die out in Canada if it weren't protected by the Language police. You probably fail the test if you don't pledge undying allegiance to la langue francaise über alle, which looks like what happened here.
If you read TFA, it says she was applying on a fast-track program for people with high proficiency. To be fair, native proficiency does not equal academic proficiency. In that type of program, the standard is probably an academic standard. Put it this way, if there were an English equivalent, none of us would pass it either. Could you give me a complete explanation of the English subjunctive verb tense, with examples please? I couldn't; I didn't even know English had a subjunctive until I looked it up. Could YOU write a thesis in English that English professors would read and approve? If not, you do not have academic proficiency in English, and you might be rejected for such a program despite being a native speaker. Not only was part of her thesis in English, who knows how bad the French part was. She prolly be like "je sais pas ecrire, mais je parl le bien verlan, mdr. can haz citoyen maintenant stp???" When I read this, I'm more inclined to see a snowflake who is surprised she didn't automatically get accepted because she's French. I have a family member who thought he could write too, until he enrolled in a Master's program and got steamrolled, native English speaker and all. In academia, native proficiency is a starting line not the finish line.
An interesting video about Canadian French accents I found the other day (video in French). I'll be honest I first thought it was about people living with speech impediments, but apparently they are genuine Canadian regional accents. And I have to admit the narrator lady's accent is super adorable.
