Hi, It depends on the weather and how far north you are going. The colors are pretty now. If you google Ontario Fall Colour Report you will see a website reporting the colors and they indicate now is a great time to see them and expecting to end over the next couple of weeks.

There are also closer-by solutions, if you don't mind walking, they just didn't suit my needs. I rather not walk around Ottawa at night at all and getting driven from the airport the safest possible solution if you ask me. You get your equivalency value after a 7-8 nights with a Caddy ride, 3-4 nights with a cab ride; both round trip. I suggest you go read on the available lots near the castle. Doing so is why I went the airport route. It's a PITA but it is the best solution... plus you can get driven around town too; old city, it's mind boggling traffic in this town, much respect to the drivers.
