In all territories owned by the Crown, including Australia, New Zealand, and the United Kingdom, the governments of those countries do not own the land of the country, but may and frequently do administer it on behalf of its owner, HM Elizabeth II. More significantly all forms of land possession in those territories are based, formally and in law, on the Crown's superior ownership. This is why the Land Registry in places like the United Kingdom, Canada and Australia cannot register land ownership, only tenure. This is also why freehold and leasehold are defined in law as forms of tenure, not ownership.

Crown land is a designated area belonging to the Crown, the equivalent of an entailed estate that passed with the monarchy and could not be alienated from it.

The Queen is the sole legal owner of all the land of Canada. The private “holdership” factor, based on freehold tenure of housing is 67%. For all other land it is less than 9.7%, with over 90% of Canadian land remaining as Crown leasehold, administered for the Crown by various agencies and departments of the government of Canada…
All physical land in Canada is the property of the Crown, Queen Elisabeth 11. There is no provision in the Canada Act, or in the Constitution Act 1982 which amends it, for any Canadian to own any physical land in Canada. All that Canadians may hold, in conformity with medieval and feudal law, is “an interest in an estate in land in fee simple”. Land defined as ‘Crown land’ in Canada, and administered by the Federal Government and the Provinces, is merely land not ‘dedicated’ or assigned in freehold tenure. Freehold is tenure, not ownership. Freehold land is ‘held’ not ‘owned’.

Within Canada, Crown Land is a designated area belonging to the Crown, the equivalent of an entailed estate that passes with the monarchy and cannot not be alienated from it; thus, per constitutional convention, these lands cannot be unliaterally sold by the monarch, instead passing on to the next king or queen unless the sovereign is advised otherwise by the ministers of the Crown. Though the Canadian monarch owns all Crown Land in the country, paralleling the "division" of the Crown amongst the federal and provincial governments, Crown Land is similarly divided so that some lands within the province are administered by the provincial Crown, whereas others are under the federal Crown. About 89% of Canada's land area (8,886,356 km²) is Crown Land, which may either be federal (41%) or provincial (48%); the remaining 11% is privately-owned.

Land ownership in Canada is held by governments, Native groups, corporations, and individuals… Since Canada uses primarily British-derived common law, the holders of the land actually have land tenure (permission to hold land from the Crown) rather than absolute ownership.
The majority of all lands in Canada are held by governments on behalf of the monarchy and are called Crown Lands.
