Onslow is home to Central Colchester Junior High School. The school is operated by the Chignecto-Central Regional School Board. Onslow also contains a small corner store, a John Deere dealership and a volunteer fire department. The area is mostly farmland but people live here also and the community is expanding somewhat. In the fall and spring, migrating Canada Geese are attracted to the farmlands and corn fields. Onslow is geographically situated in an area with high winds. This makes it an excellent location for wind turbines. Some farmers in the area have chosen to erect wind turbines to power their farms.
