> Out of all the French dialects included in the dataset, Canadian was the only one with different wording. I'd be curious to hear from someone who speaks French about whether the Canadian version has words that are actually not used elsewhere or if it's just a matter of choice of words.

As a CA_FR speaker, I think it's a bit from column A and a bit from column B. Tho, regional differences exists everywhere so I can't be absolutely certain. Proximity to EN_US and EN_UK probably affected CA_FR differently. Levels of language also affects the variety/frequency of anglicisms.
