Had an idea about this domain name and how it could be developed.
I live in Waterloo region and on my local city website portal there is a widget that shows hospital waiting times.
So you look it up and you can decide which hospital to go to depending on waiting time.
Emerg.ca - could be used for similar serving ads, then expand it to walk in clinics.
There would be tons of page views and someone could make decent money.
I thought of this domain as soon as I saw the feature on the city website.
