No, they're not really.
Alberta (i.e. the provincial government) isn't struggling to keep them, it's actively discouraging them from staying. They're getting underpaid, public schools are underfunded and overcrowded, the curriculum is being rewritten by racists to promote a Eurocentric perspective (along with "don't bother with university," and "O&G are our friends!"), and generally making things as horrible as they can.
They are deliberately, methodically, maliciously driving good teachers away from the province and undermining public education, in order to force the adoption of charter and private schools.
There is no struggle, only harm.
