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. PS 3280's effective date is April 1, 2021. Earlier adoption is permitted.


MFOA has developed a toolkit to help municipalities implement the new standard. This toolkit is free for members. To access the toolkit, please sign in and download from the link below. If you are not a member and are interested in accessing the toolkit, please contact Shira Babins (
