Mineral Development and Lands Branch Policies

In the April 17, 2020, ENDM Bulletin, the ministry acknowledged that the COVID-19 outbreak and related public health requirements are special circumstances that have created challenges for all claim holders in Ontario. Given the present uncertainty over when current health and safety measures will ease, we acknowledge that some claim holders may be having difficulty planning work programs. We are aware that exclusions may help promote public safety, particularly in remote areas, as they would reduce the need for travel into those areas for purposes of exploration. As a result, we will continue to offer a streamlined process for processing requests for COVID-19 related exclusion orders under the Mining Act and for all claim holders with anniversary dates on or before July 31, 2021.

Claim holders with claim anniversary dates on or before July 31, 2021, will be given an exclusion order if they make a brief request via email citing COVID-19 as the reason the exclusion order is requested. There will be no cost for COVID-19 related exclusion requests. The exclusion orders will remove the requirement to perform and file assessment work for a period of time of up to 12 months.

To obtain an exclusion order, claim holders or their authorized agents must email the Provincial Recording Office at pro.ndm@ontario.ca no earlier than the 30th day before the anniversary date of your claim and no later than 4:30 PM Eastern time on the anniversary date. For more information, please see this bulletin.


The ministry is in the process of reviewing and updating its policies to reflect recent changes to the Mining Act as they relate to the implementation of online mining claim registration and an electronic Mining Lands Administration System (MLAS). Until further notice, visitors should consider this content to be in transition and subject to modifications.
