Arrived in Ottawa today for OLS. Managed to get in early enough to make it over to the new (2005?) Canadian War Museum. Unfortunately, there was only two hours left before close. Two hours was not nearly long enough to do the museum justice. Even if you have been to the previous war museum you should go again. The new building is gorgeous and there is lot more stuff to look at. If you like to read everything in a museum, you need to budget a LOT more than two hours.
For those new to Ottawa, walking to the war museum from OLS will take under 30 minutes.
