You row a canoe using oars safely attached to the canoe. You can easily modify a canoe into a rowboat with oars and an accurate position to hold them. Oars are quite lengthy, so you can comfortably sit and row on both ends of the canoe as long as you keep the blade straight. Rowing a kayak on the other hand only requires a single paddle with a blade on both ends and functions differently.
