The Lester B. Pearson School Board is one of the largest school boards on the island of Montreal and one of the nine English school boards in the province of Quebec. It is headquartered in Dorval, Quebec.

Dorval is an on-island suburban city on the island of Montreal in southwestern Quebec, Canada. In 2016, the Canadian Census indicated that the population increased by 4.2% to 18,980. Although the city has the largest surface area in Montréal’s west side, it is among the least densely populated. Montréal–Pierre Elliott Trudeau International Airport constitutes about 60% of the city's land; consequently, all of Dorval's population is concentrated in the southern part of the city.
