All of Senneville lies over dolomite. In contrast to the monotony of this bedrock, there are many types of soil in the municipality. Clay is common near the northeastern corner and part of the western shores. Sand dominates many inland areas; it is rapidly drained in places but often has impeded drainage due to the type of hardpan which develops in podzols. Near-shore areas along the northern margin have extensive areas of glacial till which forms a calcareous well-drained loam. The loamy slopes overlooking Lac des Deux Montagnes are excellent for fruit trees and tender plants due to fertile soils, good drainage, and the moderating effect on microclimate provided by the lake.
