Yes ... 2.5h is the best-case scenario, given the minimal traffic at 4 AM, online check-in and carry-on luggage only. It's a crazy wake-up time but it does allow me to get into our US office by 9 AM, without having to leave the night before.
But in the end there is always some chance of a catastrophic delay that can cause you to miss a flight: an accident that blocks the 401 (before Google can direct you to take an earlier exit for a detour) -- or some level of a systemic failure that causes a train to cease running. The train failure is more rare but it can still happen. But flights can get cancelled, too: we just need to make our plans so that a travel delay will not have a massive impact. (For example, don't plan to arrive in Miami 2h before your cruise departs.)
