Deputy minister (Canada) country Canada
In Canada, a deputy minister (DM; French: sous-ministre) is the senior civil servant in a government organization, who acts as deputy head. Deputy ministers take political direction from a minister of the Crown, who is typically an elected member of Parliament and responsible for the department. 
The Canadian position is equivalent to the position of permanent secretary in the United Kingdom and the Australian position of departmental secretary. This position should not be confused with the deputy prime minister of Canada, who is not a civil servant at all, but a politician and senior member of the Cabinet.Much of the current management structure of the Government of Canada – including the role of deputy heads – originates from the Royal Commission on Government Organization, also known as the Glassco Commission.
The title is not only used for the federal (national) government, but also for equivalent positions in the provincial and territorial governments.Clerk of the Privy Council
The most senior deputy minister in the Canadian federal government is the clerk of the Privy Council, who is deputy minister to the Prime Minister and head of the Public Service of Canada. In the provinces and territories, the position fulfils a similar function as the most senior public servant and is called the cabinet secretary or clerk of the executive council. This person, along with their staff, typically develops agendas for regular Cabinet meetings, reconciles differences between departments, guides major policy initiatives, and coordinates the appointments of departmental heads. The position reports directly to the relevant prime minister and is typically among the most seasoned, influential, and low profile of public servants.
The Australian equivalent is the secretary of the Department of Prime Minister and Cabinet, and the British equivalent is the Cabinet Secretary.  The equivalent in the provincial governments of Canada is the named "Deputy Minister of Executive Council and Secretary to Cabinet" (Alberta), "Deputy Minister to the Premier and Cabinet Secretary" (Saskatchewan) or similar.
