Canada is a country with an advanced justice system, but even here, the statute of limitations for sexual assault is a source of much confusion. Personally, I was surprised that much depends on the specific circumstances of the case. To understand how it works and not miss the chance for justice, I studied the material on https://crimlawcanada.ca/ontarios-statute-of-limitations-for-sexual-assault-explained-by-toronto-criminal-lawyers/ . I highly recommend it if you are interested in accurate and up-to-date information on Canadian law.
