Is this high risk

We see alot of threads here about members having their bikes stolen even in locked parkades with different security mechanisums. I am a Doctor and I work at SPH and VGH, there are nights when Iam on call so i stay there over night. So do you guys think that I am taking a large risk of having my bike stolen when parking it at the hospital parkade over night or even in the day time? Is parking anywhere in the downtown vancouver area pretty much risky?

thanks
