Introduction to Policies

This segment of the Mines and Minerals Website contains Mineral Development and Lands Branch operational and administrative Policies. These policies are developed to aid clients on implementation of relevant Mining Act provisions and Regulations.

Note: Policies can change on a frequent basis. For the most current version, check with a provincial mining recorder.

Under subsection 35(2) of Ontario's Freedom of Information and Protection of Privacy Act, the Ministry is required to make these policies available for public viewing in a reading room or designated office. The Ministry of Northern Development and Mines has chosen the Internet as the reading room that can reach the widest group of its clients.


General Word Index

The General Word Index lists most key headings alphabetically, primarily using the titles of the subjects, paragraphs and subparagraphs. The General Word Index is common to all 3 broad topics (General Administration; Leases, Licences, and Patents; Unpatented Mining Claims).

Policy Numbering System

The numbering system for the policies is based on the prefix of the broad topics (G.A. or L.P. or U.C.), chapters, sections and titles.

The 3 broad topics and prefixes are:

Each broad topic is subdivided into chapters. For example Staking is the third chapter under the broad topic Unpatented Mining Claims. All staking policies are in the U.C. 300 series.

Under the staking chapter, there are several several sections such as Staking Methods- U.C. 301 and Staking: General Topics - U.C. 303. The section numbers are further divided into titles. For example the policy titled Staking Placer Deposits is assigned the number U.C. 301-1 because it is the first policy in the section on staking methods.

Layout of Text

The contents of the policies are laid out in a pattern of margin captions, paragraph headings and sub-paragraph headings. For an example see Indexes below.

The margin captions, e.g. Indexes, introduce the theme/topic of the text which follows. Paragraph headings further focus your attention on the theme/topic and help organize the flow of thoughts. Paragraph headings decrease the need to repeat words. They are the first words in the paragraph and should be read that way.

Sub-paragraph headings help to keep the paragraphs short and easier to read. A paragraph that is several sentences long is hard to digest mentally.


To help you find what you are looking for, there are two indexes: Key Words Index and Policy Index.

Key Word Index
lists all the key headings alphabetically, primarily using the titles of the subjects, captions, paragraphs, and sub-paragraphs. The key word index is common to all 3 broad topics.
Policy Index
is basically a table of contents. It lists all the titles of the policies in numerical order within the broad topic.

Latest Issue/Revision Dates

Latest issue/revision dates are added to the Policy Index to help you keep track of the latest policies or revisions, at a glance. The actual policy has the Date Issued under the policy number. If the policy is revised, the Date Issued changes.


In some policies you will find the margin caption Definitions. These definitions are used to build a glossary of terms. Law dictionaries are often the source for definitions.
