I see the reaction to what was said, but not what was said. How can we determine if its actually "horrific" and "hateful" without knowing what was said? 

How far is the Board expected to go? So, if parents of a certain religion don't want their kids taking art and music classes (!!!), this is acceptable and a charter right that must be enforced? What if the next accommodation is "I don't want my kids in the same class as non-believers or apostates? I don't want my kids taught by a teacher of different gender?" How far is the school board, and by extension parents with children in the Peel school system (me!) supposed to bend over?

No, the best way to make sure everyone's rights are met is to have completely secular public schools - and if someone in the upcoming provincial election wants to do away with the French and English Catholic school systems, I am all for it. Religious indoctrination can happen in your private school/church/temple/holy ground at your expense.
