Channel 8 is an analog station (is your TV set to capture digital signals?) and its transmitter tower is less than 4 miles away from your location so one could probably pick it up without any antenna at all (guess you have discovered that). 8 is an analog repeater station for Ottawa digital channel 4.1.
Based on the signal levels in the TV Fool report and my past experience near your location I would probably be able to get around 9 stations with my batwing so the reports of others receiving 5 to 8 stations with their batwing antennas makes sense.
