I'm not sure I know what you mean by communicate or connected.
Our systems communicate with one another, but they certainly don't communicate with those of the Canadian Forces. They aren't integrated because the technologies aren't the same. We have systems that date back to the 1970s, and we've just launched ones that were created in 2019. Some technologies are based on the programming languages COBOL and Fortran, which those of us who are older, like myself, used in university. Other technologies are web- or cloud-based, and that's a whole other ball game.
However, to reduce the time it takes to receive veterans' files, we have an agreement with the Canadian Forces, which grants us access to their health information system. Now, instead of requesting the transfer of a veteran's medical records, our adjudication office can simply look at them online. We still don't have the capability to transfer the file to our system, but I'm not ruling out the possibility that we could at some point.
