Can anyone come up with an explanation for this flight?
Some Cannuck Pilot needed some extra hours, decided to take the long way down south 
From the tracking page for this flight: At least part of this flight occurs outside of FlightAware’s service area. Information on this page may be unreliable.
Well yes, except the ‘unreliable’ part appears to be within the US. Looking at the log between 12:48 and 14:20 there is just a single contact with ODAPS although I would certainly not expect a flight to have really been out of touch for such long periods. I’m assuming FA extrapolated the flight path during the ‘missing’ time and then readjusted back to the actual path when contact info reappeared.
Or something entirely different. 
Maybe the pilots kids were acting up and he had to use the old “I will turn this plane around if you keep it up.” Then they started behaving so he turned back around.
I think you hit the nail on the head. This is the most logical explanation!
It makes sense to me! 
Very interesting. If you look at the previous flights for ACA967 the flight times are fairly consistent. I think a controller mistook his scope for an Etch-a-Sketch for a few minutes!
Pilot forgot he promised an old girl friend a fly-by. She lives in Sparta, Allegany County. Turns out she wasn’t home. Headed back over the Ocean so wife would suspect nothing.
LOL
Might just be me, but it looks like “half” of an airplane…maybe trying to imitate that C750 flight a while ago:) Do you all see it? The wing has a short cord and the tail is somewhat odd as well! Ok, maybe I am stretching it!
