The school had a library, science labs, tech shops, a cafeteria, an auditorium, two gymnasiums, tennis courts, and a sports field with an oval track known as the R.D.

During the late 1960s and early 1970s the Ottawa School Board experimented at LHS with extended freedom for students, allowing optional attendance at class and exemption from exams if they maintained consistently high grades.

LHS offered a full high school curriculum including over 100 basic, advanced and enriched courses, and special technical options.

The City of Ottawa was interested in keeping this community landmark in public hands, but the School Board was unwilling to compromise on the sale price.

The Board subsequently sold the school on July 18, 2007, to $21.26 million to Clyde Baseline Developments Inc., a subsidiary of SmartCentres.

[5][6][7] In July 2009, the school site was turned over the Ottawa's newly formed emergency response squad for disaster simulation manoeuvres.
