Cillyx5, I have gotten 2 extensions on my visitor status one was after we sent in my PR application. For that one I did put that I was living with my husband here in Canada. They did want proof that my husband was approved to sponsor me and that I had done medicals. Although my husband had been approved a few months before our immigration consultant suggested I still ask for a 2 year extension just in case things with CIC got messed up, because we all know they can. I was approved for a 2 year extension back in March 2015 and just this last weekend on August 23 my PR app went to DM. I am an October 16, 2014 applicant. It looks like you applied in June of this year, although you may get DM by the end of the year, and I hope you do as the waiting can feel like life passes you by, do not count on it as it could be several months into 2016 before your DM. I would be proactive with an extension always better to be safe than sorry for any reason.
