Toronto Pearson (YYZ) Runways
Ever wonder about why the runways at Pearson have their names or why some get used and others don’t?
Runways are labelled by the first two digits of the compass bearing. These designations correspond to the direction the airplane is heading towards during landing. When more than one runway points in the same direction, the runways are labelled Left (L) or Right (R).

Runways are assigned based on a number of factors:
Wind direction and wind speed
Weather
Runway conditions/availability
Type of aircraft
Operational efficiency
Time of day
