CAAC is only a sports center sponsored by CAAC and does not handle any CAAC business. Out of Union Station, the building was plain, but the relief of Indians in front of the door was exquisite. Around the back doors, you can see the red maple leaves on the wall representing Canadian Airlines and the green maple leaves on the cement pavement. As the host of many sports events, there are bronze statues of a group of hockey players in front of the door.
