That distinction is not correct. Anyone who teaches can be called 'enseignant(e)'; professeur regularly applies to specialised 'teachers' in higher educational institutions, usually with a particular field of interest rather than a general teacher, or with a higher degree underpinning their standing. It appears Canadian use may be different to French use, but in France professeur is definitely not limited to University personnel.

So in the exercise "It's not my fault" - the vocabulary specifically said a "secondary school teacher" - professeur was used in the translation. I am confused with your response.

Yes, the term 'professeur' applies to secondary school teachers, and the description does too, so there is no inconsistency. Recently there has been adoption of the term for primary school teachers as well, although that had not been the norm previously (instituteurs)- and I am unaware of how widely this might have been adopted/accepted. Professeur is correct - the question is whether enseignant(e) is an acceptable alternative - I think its use here would be replacing a specific term with a more general descriptor, and from discussion with native speaking family and friends here, including retired teachers, that would not be usual. (It could be that has changed among a younger generation - there is an age bias in my contacts).

Thanks Cécile - so why then make a distinction in the exercise - vocabulary specifically said - teacher (secondary school) - this is confusing. Unless it was indicating that the reference is to a teacher at a shool and not at a "yoga place" - for instance.
