The Canadian Heraldic Authority does not have confirmed symbolism for this emblem. The following comments are hypotheses only. The three martlets and the combination of red and white are often found in Scottish McGill coats of arms. The crescent possibly alludes to a gorget, which Mr. McGill would have worn as part of the uniform of a senior officer in the Montréal Militia. The ermine refers to his occupation as a fur trader.
