What happens if the Supreme Court of Canada denies leave to appeal a decision?

When the Supreme Court of Canada denies leave to appeal a decision, this means that the decision made by the court below—whether it be a provincial court, a federal court, or an appellate court—remains in effect. In essence, the lower court's ruling is confirmed as valid and enforceable, since the Supreme Court is choosing not to intervene or reevaluate that decision. This action reflects the court's discretion in determining which cases warrant their attention and resources.

While it may seem that the denial of leave suggests that the Supreme Court is making a decision, it is important to recognize that this does not involve a detailed examination of the case or its merits. Rather, it simply indicates that the court has opted to uphold the lower court's ruling without further judicial review.
