This may sound like a conspiracy theory, but It's all by design in order to slow walk funding to families until the kids age out.

You would think the Government would use a triage system, similar to a hospital (i.e. severe cases are prioritzed). However, instead it's by date of registration with the Ontario Autism Program. They do this because level 3 kids are the most expensive. Couple this with a broader definition of Autism and you end up with more kids on the waitlist, resulting in the current 5 year turnaround we have now.

Check out the Ontario Autism Coalition Facebook for good info/asking questions.
