Drawing of a mastodon skeleton by Rembrandt Peale In the late 1990s, a tourism attraction named Mastodon Ridge opened near the town's highway exit, based on a local discovery of a Mastodon skeleton.

Stewiacke is home to, a pharmacy, a grocery store,  hardware store, an 18-hole golf course and a newly built elementary school that consolidates 2 former local schools.

Stewiacke is also home to a volunteer fire brigade that was the first department in North America to use specialized foam as a fire suppression agent. Alongside other achievements involving the implementation of certain fire apparatus.

The town is noted as being located halfway between the North Pole and the Equator (Actually in Alton, Nova Scotia). Controversy in the past over this claim stems from the fact that the Earth is not a perfect sphere, and therefore the halfway mark lies approximately 16 km North of the 45th parallel.
