Sounds like a good opportunity to teach them some history of the country. When we celebrate Victoria Day we should have an idea of what and who we're celebrating instead of just taking off a long weekend. Knowledge of history in this country is an embarrassment.
You could do that and still rename the school after someone relevant.
They should change the name of Victoria Day too.
The school was not named for reasons of the Queen's ethnicity or religion aka WASPness.
But renaming it after, say, an accomplished resident of Parkdale would be "tribal"?
