Ads at Toronto Union Station

I walked over to Union Station on my lunch today and I notice that the station has had a bit of a face lift.

There's a small 'court yard' between the Union Go station and Union subway station and it is filled with new ad stands. They're free standing ads that are eye catching. The ones that most applied to me were the Telus Motorola Q and Nintendo's DS Brain Age.

Also, when you walk into the subway station from the 'court yard' the walls are covered with Nissan Versa ads instead of those dull off while tiles. I know that there is a lot of traffic that walks through that court yard. I'm just wondering if anyone else has noticed additions. The one thing I'm really courious about is how much it cost to post and ad in one of these stands.
