There are programs throughout the world that have apps that will tell you where the closest AED is. There is one, I believe, in Canada as well. I don't think there's one in Ontario at this point in time.
Yes, that would be beneficial in buildings where AEDs are already in place. If it's a building where an AED doesn't already exist, then it's not going to help in that situation, but having more knowledge of where AEDs are present, for the public to be able to access them, would definitely be an asset.
I know you mentioned that you were in a medical building. Not all medical clinics are even required to have AEDs in some situations, so there may not necessarily be one in those offices, even though there is a doctor's office there.
I think it's two separate issues, yes.
