I totally agree.
To give you an idea of the forms involved, when you go to the funeral home after your loved one has died they'll give you up to 18 death certificates to disseminate to the various departments. Sometimes people have to go back and get further copies because often an official copy is needed.
To maybe answer your question, I don't see that it is a staffing issue. If I have to go to 27 departments I'm still talking to 27 people. I would think that Service Canada is the one stop for me, who then notifies those 27 people.
I hope that's the easy solution. It may not be, but I don't see that's an obstacle.
