How do you intend to get to downtown Buffalo from the train station?

The train stops in DEPEW, NY not downtown Buffalo.

If you want the easy way to Toronto try Megabus from Buffalo airport which is much closer to the train station than downtown Buffalo only problem is the bus is not till like 2 PM.
I do not know what cab fare is to downtown Buffalo or the airport

BTW the average delay lately for the LSL to BUf is about one hour
