I feel like you're definitely safe for Oz, possibly Ryerson too (it's only their second ever intake so idk). I feel like you have an above-average shot at U of T as it is given all your other factors (e.g. GPA, ECs) but if you're looking to be absolutely safe I'd suggest maybe studying over Christmas and having another go in January.
Just to add to the thread - received my "assessment has begun..." email this morning. I applied October 20th but all documents (references, transcript) were processed and shown on the portal by Nov 5th
