Widebody aircraft are optimized for longer flights than their narrowbody counterparts. Thus, they have a lot more wing, fuel capacity and structure needed to accommodate this. That adds a fair amount of weight.
Think of it this way: a narrowbody aircraft has one aisle for 6 seats per row in economy. The aisle is necessary (obviously) but requires space on the aircraft that doesn't provide revenue. In Air Canada's Boeing 787s, there are 2 aisles for 9 seats per row in economy, resulting in 4.5 seats per aisle. Again, this is necessary given the logistics of loading and unloading.
Yes, on a widebody you have fewer pilots per passenger, but the costs of a pilot on a given flight are low relative to the costs of fuel. The number of cabin staff is regulated according to the number of passengers, so there's not much savings there.
Finally, a single widebody aircraft is usually more expensive than 2 of narrowbody counterpart. They're (usually) designed with fewer cycles in mind, as they were conceived as long-haul aircraft. So each cycle costs more.
So, unless there's a large fare premium for many passengers to fly at a given time, or there are restrictions at an airport (e.g. landing slots), Air Canada can run 2 Boeing 737-MAX8s (338 passengers) more cheaply (and profitably) than one 787-9 (298 passengers).
