Travelling by Air Canada?

Hello i booked a flight with a travel agency in Toronto. He sent me this link to this site: https://www.virtuallythere.com. Where i can check my reservation. Is anyone familar with this site? Since i am travelling to Riyadh, Saudi Arabia. I have so many connecting flight by Air Canada. First depart from edmonton to Ottawa to Halifax to St Johns to London (Qatar airways) to Doha to Riyadh - 26 Hours in total. Now my question is i am getting this message on top that says : http://img818.imageshack.us/img818/4305/unledkz.jpg. What does that mean? Is travel agency guy faking with me or something? Also with all these connecting flights by Air Canada do i have to transfer my carry-on and checked baggage by myself? Thanks
