Checking in early on the 26th is near 100% unlikely to be accommodated by the hotel

book and pay for the 25th. When you make the reservation call Marriott and ask for a note in your reservation to say you’ll have a late checkin/early am checkin on the 26th

subject to when you leave Toronto the Marriott app will also allow direct chat to your hotel. I say when because I don’t think you can chat with the hotel in the app until about two says prior. I’ve used that in the past to great success to make note of arrival times
