I am going to Abu Dhabi next month to visit my Dad who works in the UAE. I will be leaving Atlanta at 6:00 AM and arriving at Toronto at 8:05 AM. I have an eight hour layover at Pearson Airport before my next flight to Istanbul where I will catch my final flight to Abu Dhabi. I am just wondering if an eight hour layover at YYZ is enough time to maybe go to Downtown Toronto to see the CN Tower? I've been to Toronto before but I've never been to the CN Tower (something I've always wanted to do. I realize that after clearing Canadian Customs, and then with security and having to be at the gate early before my next flight I will have less than eight hours. I just don't want to spend the whole time in the airport, but I will if I have to. What would be the quickest or the cheapest way to get to the CN Tower from the airport and then back to the Airport? Also, since my luggage will be checked all the way through, is there somewhere at Pearson that I can store my carry on luggage? Thanks.
