My mother has family in NS (haven't been there since 1981) but the bars sounded like something my Aunt Wineva made for family tea - a weekly family gathering full of calorie rich treats and lots of milky tea for the kids. She called them chocolate bird bars - but she never called anything (or any one) by the right name. Unless she was mad at you...then it was all three names (or more in my cousin Steven's case) with nary an extra syllable.
I might just try to bring those for a family gathering. Wonder if my mother would remember them?
