Yep. A minor third is a common interval for modulations because a tune that runs up or down a melodic scale leads right into the modulation.
I was thinking of it recently when I was grabbed, at an open mic, to accompany a singer performing a parody of “The Street Where You Live” from My Fair Lady. That particular song has a really quick (4 bar) modulation in the bridge. Starting in C, it goes to Ab, Bb, and then resolves to Eb (a minor third up from C) before dropping right back down to Dm7 (essentially an F over D) and G.
