I'll take the first stab at it.
We actually do have some studies that have been done. They're just done in points of time. For example, in Ontario there was a study in 2010 that looked at one year and made projections for upcoming years. This is happening only in Ontario. However, whenever you apply for medical residency positions, you apply across the country. This is a nationwide problem. We need a central or national database so that we can work in collaboration with the provinces and territories to collate all the information from the localized studies that are happening in short periods of time. Basically, you would have longitudinal studies in a central location so that we could make that data available and use that data effectively.
