If your canoe lacks grab loops (most Wenonahs do) and you want to have them available to secure painters, use as anchor points for end lines for car topping, or for carrying the boat, it is easy to do on a Royalex hull as there are no flotation tanks to get in the way.
You can just drill a pair of holes through the hull at the stem back about 1 1/2" or so from the very tip. Place these high enough that your grab loop will not drag in the water when underway. Take about a foot, or a little less, of synthetic rope about 1/2" in diameter or some 1" wide webbing. Tie a figure of eight stopper knot at one end and pass it through one hole from inside out, then back through the other hole from outside in and tie another stopper knot. Alternatively, you can tie the 2 ends of the loop to each other after passing it through the 2 holes using a fisherman's knot.
Webbing is a little easier on the hands than rope if you intend to use the grab loops as carry handles. Tie your painter on using a bowline knot.
