RCMP Commissioner Bob Paulson says the new National Division replaces what used to be known as A Division.
In addition to corruption cases, it will also provide protection to Canadian dignitaries domestically and internationally and protect designated sites in the Ottawa region.
The Mounties say the division will strengthen the force's ability to ability to investigate and mitigate significant threats.
The RCMP is subdivided into a number of divisions, most of which concentrate on various geographic areas.
For example, O Division is responsible for Ontario.
The new National Division will be based in Ottawa, but will have a much broader reach.
Paulson says the division is committed to safeguarding the country's political, economic and social integrity.
"Canadians value the integrity of our democratic institutions and I know National Division is up to the challenge of carrying out this responsibility," he said in a news release.
