Kenner Collegiate was built by Eastwood Construction in 1952 with a small gym nicknamed the "broom closet" and a two story building containing approximately 16 classrooms. In 1957, another 16 classroom wing, including a sewing room, two laboratories, and a smaller gym attached to the north wing on the south side of the school was constructed. The cafeteria was upgraded and the woodworking and machine shops were added and fully functional.
The south wing and the main gym, that could also function as an auditorium, was built in 1966 and 1967. The south wing at the time was only one story, unlike all the other wings, which were two.
The final main attachment of the school was built in 1972 and consisted of an auditorium, library, and more classrooms. It was also the area of the commercial classes. In all, the new west wing added a commercial shop, enlarged shops, a second story to the south wing, a library, and an auditorium. This expansion nearly doubled the schools size to accommodate the increasing number of students enrolling at Kenner.
In more recent years no new major attachments to the school have been made, but there have been many upgrades done within the school. In 2015 Kenner`s library was upgraded to become the Learning Commons complete with personal electronics charging stations, a lounge area, conference rooms and a computer lab. In 2016 Kenner's Hospitality Kitchen and classroom was expanded and completely redone and in 2017 Kenner's Auto and Small Engines shops were given a complete overhaul with new equipment, new cabinets, new tools, new desks chairs and technology.
