Let's take the case of an individual who is applying to come to Canada permanently. We're looking at a permanent resident visa; therefore, we're going to be going through all the health checks. A person has to go through a lot of different checks, and their medical could take time. Sometimes we've found that the medical takes time because of the individuals themselves; they don't get the medical checks they need to have done. If it's not that, it may be that they are waiting for security clearances.
There are many different spots in the process when an individual's application is pending. It depends on an individual case; it could be for security, for health, for criminality checks—any of those.
