This is a list of Canadian royal commissions or commissions of inquiry since Confederation.

In Canada, royal commissions and commissions of inquiry are official inquiries into matters of national concern, either in order to look into an important general issue or to fully investigate a specific incident. They are appointed by the governor-in-Council (Cabinet), according to the Inquiries Act, by an order-in-Council that includes the names of the commissioners, the terms of reference, and the body's powers; commissions are often referred to informally by the name of the chairperson or commissioner(s), such as the "Gomery Inquiry", a commission headed by John Gomery. The findings are reported to Cabinet for appopriate action; while these are non-binding, many have a significant impact on public opinion and the shape of public policy.

The Crown in right of each province can also appoint a royal commission. Federal inquiries are limited to matters within the constitutional jurisdiction of the Parliament of Canada; they can only look at issues within provincial jurisdiction that are connected to federal jurisdiction, such as policing on-reserve, child welfare on-reserve, etcetera. Other types of federal public inquiries include task forces and departmental investigations.

Since the 1960s, royal commissions have tended to be reserved for broad topics, whereas commissions of inquiry have more focused. From 1867 to 2013, there have been almost 450 federal commissions of inquiry, with and without the royal title; more than 1,500 departmental investigations; and an undetermined number of task forces.^[1]

An inquiry called by the federal government into matters of national concern are known in Canada as royal commissions or commissions of inquiry. These consist of a panel of distinguished individuals, experts, or judges convened by the governor-in-Council (the governor general acting on the advice of Cabinet) to look into and secure advice for an issue of general importance or to fully investigate a specific contentious incident.^[1] The same order-in-Council forming the commission will also set out the terms of reference for, and powers of, the commission.^[2][3] This is done according to the Inquiries Act, which was first passed by the Parliament of Canada in 1868 and provides royal commissions, commissions of inquiry, task forces, and departmental investigations the power to conduct investigations by subpoenaing witnesses, taking evidence under oath, requisitioning documents, and hiring expert staff.^[1]

Once the commission's task is complete, its findings are reported to Cabinet for appropriate action.^[2][3] While a commission's findings and recommendations are non-binding, many have a significant impact on public opinion and the shape of public policy.^[3][4]

In practice, royal commissions can be seen as commissions of inquiry under the Great Seal of Canada that carry a royal title;^[1] though, apart from this distinction, there is no effective difference between the two. Royal commissions tend to be thought of as broader in scope than other public inquiries, often holding nationwide public hearings and publishing associated research reports, as well as their formal findings and recommendations.^[3][5]

There are several different kinds of commissions of inquiry, which can be established under either Part I or Part II of the Inquiries Act, or any one of 87 or more federal statutes. The mandate of a commission of inquiry depends on the nature of the issue to be considered.^[4] Advisory commissions usually have a broad mandate in order to ensure that commissioners consider all options and consult all parties with an interest in the matter,^[4] whereas investigative commissions typically have a more specific, focused mandate.^[4] Commissions of inquiry created under Part I of the Inquiries Act are considered to government departments for the purposes of the Financial Administration Act (FAA). Oftentimes, the prime minister is given responsibility for the commission for the purposes of the FAA, thus enabling the commission to receive administrative support from the Privy Council Office.^[3]

Other types of public inquiry in Canada that are closely related to royal commissions include^[1] task forces, which are normally composed of knowledgeable practitioners appointed by government departments to conduct concentrated investigations into specific practical matters. In the past, they have been assigned to look into such matters as privacy and computers, immigration procedures, retirement income policy, labour market development, fisheries policy, and sports. Though usually not as wide-ranging as royal commissions, some task forces have dealt with broad issues, such as housing and urban development, government information, and the structure and foreign ownership of Canadian industry.^[1][6] There are also departmental investigations, which can be established by departments and other agencies under statutory powers of the Inquiries Act.^[1]

Federal inquiries are limited to matters within the constitutional jurisdiction of the Parliament of Canada. They can only look at issues within provincial jurisdiction that are connected to federal jurisdiction, such as policing on-reserve, child welfare on-reserve, etcetera.^[7] The Crown in right of each province can also appoint a royal commission, although, they are not included in this list.

Many of these are task forces in miniature.
