The Montfort Woods are protected by the designation "National Interest Land Mass."

REPORT TO THE OTTAWA PLANNING AND ENVIRONMENT COMMITTEE. Subject: Official Planning and Zoning. June 29, 2004.

Background. The site is situated behind the Montfort Hospital with a partial frontage on Lang's Road to the east. The site, known as Montfort Woods, is a natural woodlot that is surrounded by the Montfort Hospital and a long-term care facility to the south, Aviation Parkway to the west, CFB Rockcliffe to the north and the Fairhaven community to the east. The site is approximately 7 hectares (17 acres) in size. 

The National Capital Commission acquired the Montfort Woods property on January 27, 2004, and submitted Official Plan and Zoning By-law amendments.

The affected parcel of land consists of a core and marginal woodland area that includes predominantly Sugar Maple, Beech, Ash, Basswood, and Norway Maple over limestone bedrock. The applicant, the National Capital Commission (NCC) wishes to protect this woodlot for future generations.
