Best way to get to Ottawa from Toronto?

[gei]

Excluding driving/renting a car... what's the best way?

Via rail seems to be $131 for union station -> ottawa (return trip)... which is quite reasonable...

But I'm wondering if there are flights that are a similar price? Perhaps ones flying out of toronto city centre airport or hamilton?

Bus would be cheaper than Via Rail, but nowhere near as comfortable. I'd go with the train and at least earn points on their Préférence program.

There is a Westjet seat sale going on, so you might be able to get a cheap ticket from Hamilton or Toronto (Pearson). However, with taxes and fees, it isn't likely to be cheaper than a train ticket. Also, for the amount of time it would take you to get out to the airport, check-in and wait for your flight, you might as well spend it downtown or on the train.
