Hi Tife,
I got that one about a month ago, and seems clear that it's not an indication that the application is approved, has a positive outlook, or anything of the sort. As a matter of fact we just got a request for further documents this week. Police checks from countries where I had lived before (not requested in the "checklist") and that's going to be a bit of a pain and a lot of an investment. But hey. I guess if you are Canadian you better marry someone who hasn't moved around much, or be ready to pay some big bucks.
