Okay kiddo, so there was this lady named Loyola who wanted to teach her religion class in a special way. But the government of Quebec said "no way, you have to teach it our way". Loyola said that was not fair and asked a judge to help her.
The judge agreed with Loyola and said that the government was not allowed to force her to teach her religion class their way. The government didn't like this and decided to go to a higher court to tell them why they thought the judge was wrong.
The higher court, called the Supreme Court of Canada, listened to both sides and then made a decision. They said that the government could make rules for Loyola's religion class but those rules had to be fair and not hurt anyone's rights. The Supreme Court also said that people should be allowed to practice their religion freely and should not be forced to teach it in a way that goes against their beliefs.
So, in the end, Loyola won and the Supreme Court decided that people should be allowed to practice their religion freely, as long as it does not hurt anyone else.
