Incidentally, I'm a graduate of Laurentian's faculty of education, and I also have a degree from the University of Ottawa.
My understanding is that the challenge is mainly about immersion teachers, and teachers who teach French. I think the shortage is biggest there. At least that's what people in the jurisdiction are saying.
Some people say there are fewer jobs, but as someone who had a career in education, I would say the situation appears mainly to be affecting urban areas. This is because people tend to want to settle near where their school or faculty was located.
By way of illustration, the shortage might be less serious in Sudbury. In Foleyet, Smooth Rock Falls, or the southern part of the province, such teachers are in great need. It's a question of mobility, and of whether one is prepared to travel to secure employment.
