"Lands of National Significance."

From: Plan for Canada's Capital-1999-National Capital Commission. Key Capital Parks include the following:

• Confederation Park
• Jacques Cartier Park
• Rockcliffe Park
• Major's Hill Park
• Rideau Falls Park
• Commissioners Park
• Hog's Back Park/Vincent Massey Park
• Leamy Lake Park
• Brebeuf Park and
• LeBreton Common (page 59/127)

"Federal buildings and grounds which are designated as national historic sites should receive the highest level of protection and their significance should be communicated to the public. (page 69/127).

Endangered Capital Parks, in my opinion:

• Queen Juliana on Carling Avenue.
• Lazy Bay Commons, located in Mechanicsville, because half a dozen foreign embassies are planned for the site.
• Major's Hill Park, because the land will be an annex to the privately owned Chateau Laurier Hotel. 
• Rochester Field, Westboro.
• Commissioners Park, due to the impending presence of high-rise condos and a sprawling medical centre. I doubt that the Tulip Festival, Canada Day Celebrations, fireworks, etc. will ever be permitted on Majors Hill and Commissioners Park again.
