In Saskatchewan, that challenge is mostly in rural schools. For example, a rural school may have 50 or 60 students and four or five teachers. You can imagine how hard it is to find a teacher from the community. Someone may really want to invest in the community, but most people from outside have no interest in living in a small rural place. The big challenge is to find people in the community who want to get a teaching degree and then come back to live in the community.
It can be hard for teachers to stay in these communities where the main economy is agriculture. Someone from Ontario might want to start a career in education, but their spouse would have to want to start a career in agriculture, for example. Otherwise, it really wouldn't work. It's very difficult to bring people in from other places.
In addition, in these small communities, it often happens that a position opens up and no one applies. No one wants to go there, because it's far from all the services offered by a big city, such as health care services, stores and so on. Many schools have unfilled positions. The other teachers then have to compensate by agreeing to work more hours and take on more tasks, and so on.
