Stuff stolen from hotel room in Toronto, On...?

My husband and I are staying in downtown Toronto. Our first morning here, we left for about an hour and a half. When we came back, we found our door ajar and noticed our netbook was missing. After we checked out the door, we noticed that the dead bolt comes out and stays out unless you open the door at an optimal speed. We came in and out of our room several times our first night and it never happened. As best we can tell, and confirmed by the hotel staff, we opened the door too quickly, and it triggered the dead bolt to remain open. When we checked back at the door after we heard it hit the door jam, it was only a cursory glance to ensure the door was closed. We certainly didn't expect the dead bolt to be triggered.

Anyway, my question is do we have any legal recourse against the hotel. The door/dead bolt phenomenon is a repeatable scenario. We showed the security officer that it could be done easily, and without notice under several opening conditions. He said it was our fault that we didn't check the door, but we feel we have a reasonable expectation of security... which necessarily includes that the door will shut when closed, every time.

Anyway, just a little flustered right now. We would certainly appreciate any help.
