I shop in Rideau center every week.
I also shop in St. Laurent shopping center often.
Billings Bridge is very close to my office, I go to TD bank or Independent or the post office or the food court in Billings Bridge every week.
Whatever Eaton center has, we have it in Ottawa. But if you shop in Toronto, you save some money for the same items coz you can just wait wait wait till the price goes to really low. If you wait wait wait in Ottawa, you won't find your size or color or they will ship the on sale stuff out to Toronto.
I also shop in US shopping malls (not outlet) every year. Twice already this year and will go again this Xmas.
