For business purposes, I traveled to Canada about 8 times in 3 of them taking advantage of the weekend trip to Niagara Falls in the year 2011 on 2 occasions and another time in 2014.
The first time we traveled coincided with Canada Day therefore the surroundings were full; the number of nationalities that I could see was amazing, most of which from the Middle East and Asia.
After taking the tour of Maid of the Mist where we boarded a barge to feel the breeze from both Niagara US side and Canadian side (to my mind the best by far). Then we continued through a series of tunnels that led us into the bowels of the Niagara Falls themselves, the feeling was impressive; being part of the power of nature showed in these falls.
