Ha! Our Canadian Thanksgiving being in October, I can say that my turkey - about the same size - took much longer than that to thaw in the fridge. I put it in the fridge on Saturday morning, Thanksgiving Day was on Monday and we didn't eat turkey until Wednesday - and even then it had to finish up thawing under running water. Fortunately we did not have any out-of-town guests.

They thaw faster in a tub of cold water - changing the water as it becomes warm to prevent spoilage. It should be left in its wrapping - or if it is straight from the farm perhaps place it in a freezer bag.
