St. Albert, with no inclination towards being absorbed by Edmonton—a sentiment further detailed in the history of Akinsdale—showed interest in expanding its own borders. In 1980, it annexed the land that would develop into Erin Ridge, one of its largest neighborhoods.

Located along the city's northern edge, Erin Ridge is home to approximately 5,960 residents, boasting an average age of 40.50. The neighborhood is designed with central parks and green spaces that enhance the scenic beauty surrounding both low and medium-density residential areas. A commercial strip on the neighborhood's lower western side is conveniently located near St. Albert Trail and the Sturgeon Community Hospital. Property values in Erin Ridge are notably higher than in many other areas, with the median listing price surpassing $500,000.

Erin Ridge is well-connected by St. Albert Transit (StAT), which provides local weekday routes, weekday commuter routes to Edmonton, and Dial A Bus services, ensuring convenient transportation options for its residents.
