What do you guys think he is

I'm going to get a DNA test for this guy on payday. I know what the rescue said he is but I'm not convinced it's accurate.

Hes 85lbs and extremely active. He loves water more than anything on earth but fetch is a close second. He loves to play, loves the snow and is not super cuddly. A very funny vocal guy who is also scared of most things. In canada.
