Within a year? You've stayed more in Canada than out of Canada. Show proof that you are still VISITING, and you don't let the officer know you're intending to stay for 6 months. What about a contract of lease for an apartment, round trip airfare (maybe something you can change the departure date for a later time).
all in all a total of 202 days. and then 3 months more i've never had any problems though i'm just freaking out a little bit now since it's been quite some time.
