CMS has also been severely overcrowded for several years. At most times, students cannot walk through its halls without encountering very heavy foot traffic. They will, however, be transferred to an all new school building that, as of 2018, has not yet been constructed, but is expected to be built and opened by 2021 at a new location and will have a larger student capacity than the current school. The name of the new building is currently to be determined, and the facility may or may not be called Canonsburg Middle School. The present-day building cannot be effectively expanded due to property space constraints and an overall original design and layout that did not take future wings and additions into consideration. The aforementioned auditorium will likely remain as-is, despite the school building's currently unknown fate after closure. Unconfirmed local rumors indicate that the building, if not demolished, may be either acquired by a church and converted into a religious school, or remodeled into apartment homes for senior citizens.
