To my knowledge, the Canadian Constitution allows Catholics in Canada to run separate Catholic schools in Canada if Catholics want to fund them but there is nothing in the Constitution that says non Catholics have to pay taxes to help pay to fund the Catholic schools. 

In Ontario, however, Catholics and non Catholics pay taxes that are used to help fund the Catholic schools. 

I wonder if some people in Ontario will use the decision in Saskatchewan to challenge the system in Ontario. 

I wonder if the Saskatchewan case will go to the Supreme Court of Canada.
