Arisaig Jackson is a character in the fourth season of Canadian Boys. He is the nephew of Antigonish.
Arisaig is a 14-year-old boy of White Scottish Canadian heritage. He has brown hair and light hazel eyes. He wears a bright red jacket buttoned in the middle with a light pink collared shirt underneath, a deep red tartan kilt fastened with a belt, a dark rose-pink bonnet with a bright blue bobble on top, and black gillie shoes with white cotton socks inside. He is Antigonish's nephew.
Arisaig has a height condition, restricting his physical growth so that he only comes up to just about the top of a person's leg - very short for a boy of 14 years old.
Much like his uncle, Arisaig is quick-tempered and will not hesitate to lash out with fury if something or someone works him up. Near-constant mockery of his tiny stature has conditioned him to rightly bite back with a vengeance.
- Arisaig has the same initials as his uncle Antigonish - AJ (Arisaig/Antigonish Jackson), suggesting close relations in their clans.
