Mining Lands Adminstration System
The Ontario Mining Lands Administration System (MLAS) Map Viewer is a public, online map that shows mining land information across Ontario. It allows users to view active mining claims, see which lands are open or restricted for mining, and understand how mining activity relates to municipal boundaries, roads, waterways, parks, and other land features. The tool supports transparency and planning but is for information purposes only and should not be used as a legal survey or for navigation. It is managed by Ontario’s Ministry of Energy and Mines under the Mining Act
The Ontario Mining Lands Administration System (MLAS) Map Viewer is an online mapping tool that shows how land across Ontario is managed for mining purposes. It brings together location‑based information so users can see where mining claims exist, where land is open or closed to claim registration, and how mining activity overlaps with other land features. The map is interactive, meaning users can zoom in to specific areas, turn information layers on or off, search for locations, and view different background maps such as imagery or topographic views. This makes it easier to understand mining land status in relation to the surrounding landscape.
The map displays a wide range of information beyond just mining claims. Users can see municipal and township boundaries, roads, lakes, rivers, wetlands, parks, and other protected areas, alongside geological and mining reference data. This helps provide context when reviewing mining activity, especially for land use planning, environmental review, or public information purposes. While anyone can access the map to view data, only registered MLAS users with proper authorization can register or manage mining claims through the system.
MLAS is managed by Ontario’s Ministry of Energy and Mines and supports the administration of the province’s Mining Act. Its purpose is to improve public access to mining land information and allow mining‑related transactions to be handled online. The map viewer is meant for information and planning support only. The province clearly states that it should not be used as a legal survey, for navigation, or to make final boundary decisions, as the data may change and is provided “as is.”
