True, however I checked with the IRCC person and he mentioned that Chinook only assists with sorting out the applications, like basically a pile of probable refusals and acceptables and he suggested to correct the things like the ones you mentioned and re apply when they are ready.
However I would like to ask one last thing, as I said I just want to invite them to spend time with me and show them Calgary, with this purpose dont I ever have a chance to invite my Parents to Canada?
I am neither planning to get married here nor have a child, so that means this is the end?
