Right but you can only sponsor extended family…dad’s cousin is not extended family. It is uncle, aunt, first cousin etc. Start the process because it will take a few years to get a response.Yea I called them to confirm...otherwise the link below does clearly states under the Other Relative section that you can sponsor any blood relative given that you don't have spouse, children, parents, siblings, grandparents, niece, nephews, and that you don't have any uncle, aunt, or any other relative already in Canada.

And yes, the call center people do say that the ultimate decision is of the visa officer.
