The Heritage Property Act broadly defines heritage property as:
- archaeological objects;
- paleontological objects; and
- any property of interest for its architectural, historical, cultural, environmental, archaeological, palaeontological, aesthetic, or scientific value.
In Saskatchewan, those heritage properties that are most commonly recognized and actively managed, include:
- Built heritage sites and structures of historical and/or architectural interest, such as: late 19th and early 20th century buildings (including residences, government buildings, churches, town halls, opera houses, grain elevators, factories, and railroad stations), as well as bridges, water towers, and historic trails.
- Archaeological sites of First Nations, Métis, Euro-Canadian or other ethnic origin that reflect occupation and use of the land and date to the province's initial settlement more than 10,000 years ago, through the "contact" period beginning around 300 years ago, to the early historic period 50 to 100 years ago. Examples include: ancient First Nations campsites, animal kill sites, and ceremonial or spiritual places (such as the Moose Mountain "medicine wheel" and the Churchill River rock paintings); Hudson's Bay Company fur trade posts; Métis settlements; Doukhobor villages, and pioneer homesteads. To date, more than 25,000 archaeological sites are known in Saskatchewan; most are of ancient First Nations origin and date to the time before "contact" with European culture and peoples.
- Palaeontological sites containing the fossils of vertebrate animals and some invertebrate animals and plants that lived in the distant geological past. To date, over 2,000 palaeontological localities are known. Examples include: late Cretaceous Period exposures along the Carrot River near Pasquia Regional Park containing marine fish, reptiles, dinosaurs, toothed birds and early mammalian fauna; the Tyrannosaurus rex locality along the Frenchman River near Eastend containing "Scotty", a particularly large, very complete and well-preserved Tyrannosaurus rex (one of only 12 known in the world when it was discovered in 1994); and Swift Current Creek and Wood Mountain localities containing early mammalian fossil from the Eocene, Oligocene, and Miocene epochs.
Those heritage properties that have been officially designated under The Heritage Property Act, as either Provincial or Municipal Heritage Property, are listed and described in both the Saskatchewan Register of Heritage Property (managed by the Heritage Conservation Branch) and the Canadian Register of Historic Places (managed by the Historic Places Program, Parks Canada Agency).
