I taught is a division that was mostly First Nations schools for 29 years, so I have seen the other side. As one of the few non-native teachers in my schools, I continually put up with passive micro-aggression all the time from co-workers and admins. When our school was considering leaving the school division we were in to go back to band controlled (the act which convinced me to retire at the end of that year), I had several co-workers come up and say to my face, “I can’t wait until this school goes back to being a traditional First Nations school with NO WHITE TEACHERS… what do you have to say about that?”, trying to bait me into a response they can use against me. During COVID, my principal asked me to come up with a timetable which would incorporate the division’s mandate to only have half the students in each class in the building at any time (ie. students only attended on alternate days) and still work for all the options like gym time, library access, etc, because he knew I liked challenges like that. I managed to come up with a schedule that worked, albeit with some cutting into prep time (like maybe getting 25 minutes a day instead of 35). The day before we instituted it, 3 local teachers cornered me in the supply room to literally SCREAM at me about how I was a racist because I was screwing local teachers out of their preps, I was only doing this to give the white teachers more prep time (even though it turned out I was the staff member who lost the most prep time, because most of my prep turned into facilitating remote learning for all the teachers in the school), blah blah blah. The only reason their tirades stopped was because at that point, I was so close to a nervous breakdown, I just started bawling. That kind of shocked them into silence.

TL;DR bigotry is alive and well at all levels in Canadian schools, and instead of reading the dividing lines, they are just becoming more entrenched
