PSAB Asset Retirement Obligations (ARO) Standard - Resources


PS 3280 is a new accounting standard covering asset retirement obligations (ARO) that was approved by PSAB in March 2018. The standard must be applied by all public sector entities who prepare their financial statements under PSAB, including all Canadian municipalities.


Common asset retirement obligations under the scope of PS 3280 have not previously been recognized by municipalities, such as obligations to retire buildings with asbestos or underground fuel storage tanks. The implementation of the standard will require municipalities to recognize obligations which were previously out of scope of accounting standards. Similarly, the accounting of obligations for solid waste landfills will change with PS 3280.  

Due to the ongoing impact of the COVID-19 pandemic, PSAB has approved a decision to defer the effective dates of all upcoming standards by 1 year. PS 3280 will be effective on April 1, 2022. Earlier adoption is permitted.


MFOA has developed a toolkit and accompanying case study to help municipalities implement the new standard. The toolkit and case study is free for members.

Municipal ARO Case Study *New*

To demonstrate the application of MFOA's ARO Toolkit, a review of five municipalities’ TCAs was performed to identify sources of ARO and provide further insights on TCAs municipalities typically own that result in ARO. The case study reviews the AROs found in five diverse Ontario municipalities. To access the case study, please sign in to our website and download the resource below.
