The number of potential candidates for immersion positions is a problem.
For example, if a position is advertised at an English-language school in my school board in Winnipeg, management can receive 50 to 70 applications. For a French teaching position at an immersion school, management will receive six applications, three of them from candidates who do not speak French.
Consequently, it is very difficult to find teachers who are capable of taking on the responsibilities of a French immersion teacher in regions in western Canada.
