Archaeology in Ontario
Archaeology and conservation of cultural resources in Ontario fall under the Ministry of Tourism, Culture and Sport. The Province of Ontario has created Acts to insure the protection archaeological and cultural resources. Acts such as the Ontario Heritage Act and Environmental  Assessment Act provide the major legal documents that protect heritage and cultural resources. Additionally, Acts such as the Planning Act, the Aggregate Resource Act and the Ontario Cemeteries Act are also implemented when specific triggers occur during archaeological assessments. The Provincial Criteria for Determining Areas of Archaeological Potential
Areas of property that are considered archaeological potential are those that could contain archaeological resources. The ministry's criteria for determining areas of archaeological potential are:
 The presence of known archaeological sites within 300 metres of the property;
 The presence of a water source (primary, secondary, ancient) within 300 metres of the property;
 Elevated topography (e.g., knolls, drumlins, eskers, plateaux);
 Pockets of sandy soil in a clay or rocky area;
 Unusual land formations (e.g., mounds, caverns, waterfalls);
 Proximity to a resource-rich area (concentrations of animal, vegetable or mineral resources);
 Evidence of early Euro-Canadian (non-Aboriginal) settlement (e.g., monuments, cemeteries) on the property;
 Proximity to historic transportation routes (e.g., road, rail, portage);
 The property is protected under the Ontario Heritage Act;
 Local knowledge of archaeological sites on the property or of the property's heritage value. The process of Archaeological Assessment
There are six stages of an archaeological assessment in Ontario. Ontario Heritage Act
The Ontario Heritage Act was created in 1975, was further amended in 1990, 2002, 2005 and as of 2009 as undergone further amendments. Under the Ontario Heritage Act, the Ministry of Tourism, Culture and Sport contains the "responsibility to determine policies, priorities and programs for the conservation, protection and preservation of the heritage of Ontario and so fills the lead provincial government role in terms of direct conservation and protection of cultural resources." The Ontario Heritage Act governs the general practice of archaeology in the province. It provides the legal framework to provide licenses to archaeologists who are qualified and it is $1,000,000 fine to alter any heritage site without a permit or license. The Act also provides protocols for assessments of archaeological sites, and "municipalities and the provincial government powers to preserve the heritage of Ontario" and focuses on protecting heritage properties and archaeological sites. In 2005 an amendment of the Ontario Heritage Act provided further implementations which:
Give the province and municipalities new powers to delay and also to stop demolition of heritage sites. They balance enhanced demolition controls with an appeals process that respects the rights of property owners. Further expand the province's ability to identify and designate sites of provincial heritage significance. Provide clear standards and guidelines for the preservation of provincial heritage properties. Enhance protection of heritage conservation districts, marine heritage sites and archaeological resources. The Act provides a clear out line of what is required of the Municipalities and the Province when it comes to cultural resources. Suspicion of illegal actions
The Ontario Heritage Act describes the roles of inspectors, who are province appointed individuals who can be qualified in archaeology or accompanied by experts, who are implemented when suspicion arises during an excavation that is related harming or threatening the publics interests. Suspicion can be related to anything from falsification of data, to falsification of what is occurring on site (either through archaeologists or developers). An inspector is able to enter any of the following. The Environmental Assessment Act
The Environmental Assessment Act was created in 1976, to help to "provide for the protection, conservation, and wise management of Ontario's environment" which relates to all aspects of determining the ecological, cultural, economic and social impact of a project. This act is related and allows for all public sector and private infrastructure projects which contain projects, like roads hydro generation, sewage, water, landfills etc. to conduct an environmental assessment. The environmental assessments are conducted so to help with planning process and provide better knowledge about the site before development and decisions on projects are created. In many instances an environmental assessment determines the need for an archaeological assessment, and it is completed as part of the overall environmental assessment process, this is a result of any public development project, land changing activities, and all land own by the Province of Ontario. An environment assessment is conducted after the terms of reference is approved which relates to a general proposal of a project and preliminary involvement and cooperation with organizations and communities that will be affected by the development. The environmental assessment is the proposal after the terms of reference which provides the results of the organizers planning and decision-making process. Which provides identification and evaluation of alternative solutions to their location if problems arise, their environmental effects on the land and community, the impact mitigation and management measures on the environment, and "record of consultation with the public, Aboriginal communities and government agencies [which] is mandatory." The Planning Act
Link to Citizens Guide to Planning Act of Ontario 

The Planning Act is an act of legislation that provides "the ground rules for land use planning in Ontario and describes how land uses may be controlled, and who may control them (planning act)." This act is provided to give Province authority to help govern and mediate between municipal and private corporations. Municipal (including planning boards) have more authority over the decisions about development of any infrastructure within their area, provide official plans they have for public development as well as any goals that are related to private enterprises.http://www.mah.gov.on.ca/Page1760.aspx Municipalities are in charge of setting out the rules and regulation to control zoning by-laws as well as must accord with all Provincial interests and plans about development. Furthermore, municipalities must reach their decisions with following other acts and regulations that may impact any development (i.e. the Environmental Assessment Act and the Ontario Heritage Act).  " Thus all decisions made during the development process, regardless of the identity of the development proponent or the relevant approval agency, must address potential heritage resource impacts." Under the Planning Act, the significance for "archaeological resources are defined as those 'that are valued for the important contribution they make to our understanding of the history of a place, an event, or a people.' The identification and evaluation of such resources are based upon archaeological fieldwork undertaken in accordance with the Ontario Heritage Act." In summary, a municipality is obligated, within the existing legislative framework, to require archaeological concerns be addressed in connection with any planning application and is able to pass zoning by-law(s) regulating the use of land that is the site of a significant archaeological resource. Moreover, a municipality is prevented from undertaking any public work that does not comply with its Official Plan. Heritage protection policies are related to Official Plans (which are plans produced by the Ontario Government related to development and land allocation), if developed and incorporated properly. If a municipality has a sound basis in its policies (Official Plan), it is possible to refuse applications that do not conform to heritage requirements. Many triggers for archaeological assessment occur in the Planning Act and are predominantly enacted by new housing developments or other residential land developments which also must comply with the Ontario Heritage Act. Other Provincial legislation
There is other Provincial legislation that can affect cultural resource management and archaeological assessments in Ontario. The Aggregate Resources Act: which provides approval of pits and quarries and administered by the Ministry of Natural Resources, recognizes the potential impact of quarrying activities that may have an effect on cultural features such as archaeological resources. The process for addressing archaeological concerns within the Aggregate Resources Act is similar to that for Planning Act- related projects. The Cemeteries Act: This act shows the need to protect human burials, both marked and unmarked graves, which can provide another link to the past. Marked burials are provided protection as a heritage resource. "Burial locations uncovered on archaeological sites constitute 'unregistered cemeteries' that are, in essence, in violation of the Cemeteries Act. The discovery of such burials will require further investigation in order to define the extent and number of interments, and either the registration of the burial location as a cemetery, or the removal of the remains for re-interment in an established cemetery." These archaeological burials can result in more complex legal issues. References
