I'd be surprised if his French wasn't fluent; to get any government job in Canada, you have to be bilingual, even cops and junior civil servants. His accent might be awful though, I suppose, like the English gendarme in 'Ello 'ello.
Er it's not like they do a fluency test to get the job, it's like how here you can get a job if you are a B1 speaker, but people can have that certificate and still speak rigid and robotic Norwegian with a strong accent
Which is what people criticize Carney for with his French.
