I'm from Houston, not sure if that matters or not, but this was my first trip to Canada. My husband and I were only in Toronto for two days so my list of things consisted of attractions we could only experience in Canada. The Aquarium did not make my list. I figured if I've seen one then I must have seen them all and I'm more afraid of everything that can eat you in the ocean than interested in getting to know the different creatures. Since this was a trip for my husband's birthday though, I gave him full reigns with our itinerary once we got there and had printed out a TripAdvisor list with the top things to do in the area while circling a few of my favorites. Although, the aquarium was on the list, it was not circled or researched any further. Once we checked into the Delta Marriott and made it up to our room, he noticed the roof of the aquarium and replaced the visit up the CN Tower with the aquarium. This was our first stop and I was hoping it'd only take thirty minutes because we had breweries and the hockey hall of fame (more fun things) to see. Ha. We spent over three hours walking around and my husband ended up having to pull me along because I became mesmerized. I stopped at the vertical tunnel of fish swimming sychronized and was envisioning Finding Nemo as they made shapes together and I was taking videos of the shark exhibit from the entry because it looked so scary and shallow and I was glad to be on the other side of the building. I had no idea there would be a tunnel that would surround you with the sharks and sea life. They had interactive exhibits where you could pet sharks and get a manicure from shrimp. I had a blast and felt like a kid. I immediately wanted to fly my two nieces up there, so I could experience the bewilderment again through their eyes. I thought Seaworld was cool until now...take me back to the Toronto Aquarium!
