The smallest jet in WestJet's fleet is the 737-600. It requires a field length of 5,900 feet at sea level for take-off. The jet will be using 95% N1 power for that perofrmance, meaning more noise on take-off and climb out.
Nav Canada Pilot's Flight Supplement shows the main (longest) runway at At Edmonton City Centre (YXD) with 5,700 ft and an elevation of 2200 ft ASL. At that altitude, the air pressure is less dense, so the aircraft needs more speed to get off the ground and therefore more Runway.
Also, the Runways at YXD are restricted to 140,000 pounds. A loaded 737-600 will weigh about that on landing, but fully loaded would wiegh more on take-off (fuel weight is higher on take-off than landing).
There is no way WestJet would try to fly their 737s out of YXD. They wouldn't be allowed to do so to start with for safety reasons.
I tried it in Flight Simulator. I took a 737-600 with half fuel and half passenger load (by weight) taxied out to Runway 16 and back-tracked to get maximum runway length. I held the brakes on - aet 15% flaps for take-off - throttle to 95% N1, released brakes and the main wheels left the ground just across Kingsway avenue. In real life of course I would have taken out the fence, lights, cars, and approach lights and most likely would have crashed.
