Canadian steel buildings

I never been to Canada yet but my family and I have some plan to go visit there in the future. I want to see their architechtural like their canadian steel buildings. Besides, I have a sister-in-law that lives there right now. I'll be glad to meet her in person and to know her more. Well, as in general I love sight-seeing and visiting new places that I haven't done here for awhile because of different priorities and obligations. I will get back in tract again soon- God willing!
