It is almost certainly a Courier. That canoe has been rerailed. The inwales and outwales are sandwiched on the hull. Although MRC did sandwich the gunwales on their Royalex canoes (as did most makers), on their composite boats the gunwales were rabbetted so that the top of the hull was not visible between the inwales and outwales. Since it was rerailed the thwarts are probably not stock and the inset deck plates do not look stock either. The canoe may have been pushed out a bit when rerailed.
Also, MRC usually measured beam at the molded hull, not from the outside point of one outwale to that of the other. So in your boat the beam of the canoe in your first set of photos is more like 33 3/4". Assuming the other end of your tape in the last set of photos is against the outside of the outwale, you have now pulled the beam in to about 29" or so, which I agree is a bit much.
