If you build it will they come?

As I am trying to renew my registration with the Alberta Registered Nurses Association, (and still waiting for California to send my varification through) I discovered that there is a new hospital being built in the province. I believe it will be a cardiac care facility. Of course when this came up in conversation I asked what had to be asked,
"and where do they plan on getting the nurses from, to staff this new facility".
The rep I was talking to couldn't really answer the question, or maybe I didn't give her the opportunity. I answered myself. Perhaps a new modern facility will help Alberta attract more nurses.
We all know they are certainly not just going to magically appear out of the sky. Some facility (s) somewhere is going to lose their nurses in order to staff this hospital. Why does it always seem to me that governments and governing boards keep spending the money in the wrong order. I don't want to say on the wrong thing, because I am quite certain, having been in Alberta myself, that some of their hospitals are in great need of updating. But how can you build and expect to staff it with nurses (someone needs to carry out the orders written) when they do not presently exist. The "hire ups" are doing things in backwards order....again.
