Ministerial discretion (Canadian law)
The idea of ministerial discretion, when employed in Canadian statute law, means the power of a Crown minister to vary or alter the decisions of their bureaucrats, one of their Committees, or one of their Boards. The idea derives from the laws of the United Kingdom, of which Canada, under the rubric of British North America, once was part. The term needs to be written into the statute, as for example in section 51 of the Canadian Oil and Gas Operations Act:

The Governor in Council may at any time, in his discretion, either on petition of any interested person or of his own motion, vary or rescind any decision or order of the Committee made under this Act, whether the order is made between parties or otherwise and any order that the Governor in Council makes with respect thereto becomes a decision or order of the Committee and, subject to section 52, is binding on the Committee and on all parties.
