2021-22 Condo Returns Deadline Has Passed


To better serve condo owners and the broader condo sector and to meet our legislated obligations to ensure the accuracy of information being added to the CAO’s Public Registry, we have made some important changes to our condo returns filing system.

We recognize that we are asking for more information in this year’s condo return about your condo corporation and that we are asking you to validate previously filed information. These changes mean that it may take a bit longer to file your condo return.

In order to prepare for filing your condo return, we encourage you to review the Summary of Information Required for Condo Returns and Notices of Change and the CAO’s Guide to Filing Condo Returns. The Guide sets out the Step-by-Step Instructions (beginning on page 4) about the information you should have on hand before you file and what you need to enter into the condo return.

Most of this information only needs to be entered once and will already be captured when you file next years’ return.


Please make sure that you are accessing your condo return via your desktop or laptop computer if possible. We have found that these devices work better than tablets (e.g., iPad, Chromebook).

We recommend using the Google Chrome web browser to access the condo returns filing system. If you are having trouble accessing your condo return, please try accessing it through Google Chrome before contacting the CAO directly. If you do not have Google Chrome installed on your computer, you may wish to download it independently.

Before you begin your return, you should clear the Google Chrome cache. This will help ensure that your condo corporation’s information is entered correctly in the CAO’s computer system. To clear your cache in Google Chrome:

  1. On your computer, open Chrome.
  2. At the top right, click “More” (may appear as three vertical dots) ⋮
  3. Click “More tools” > and select “Clear browsing data”.
  4. At the top, in time range field select “All time”.
  5. Next to “Cookies and other site data” and “Cached images and files,” check the boxes.
  6. Click “Clear data”.

As part of the CAO’s mandate to protect condo consumers, it is important that accurate and up-to-date information regarding licensed condo managers and condo management companies is filed through condo returns.  To improve the integrity of the CAO’s records and provide better service to Ontario’s condo communities, we have introduced lookup fields as a way to ensure that information, like addresses, is accurately and consistently entered into our system.

When you fill out your condo corporation’s return you must provide certain information such as the condo manager’s address for service and the condo’s municipal address using the CAO’s new address lookup function:

  • When entering this information, place your cursor in the box labelled “Please search for the [address] here”.
  • Start typing the address information (e.g., municipal address).
  • Options for the requested information will appear on screen.
  • Choose the correct option from those provided.

DO NOT continue entering the address manually, since the format you use may be different from the CAO’s records.

  • If you see a “save” field, make sure to select it before moving on to the next screen.

Note: you must also use this address lookup function to find the condo management company’s address for service.


As part of the CAO’s public protection mandate, it is important that the CAO’s Public Registry only publishes the names of condo management companies and/or individuals licensed by the Condominium Management Regulatory Authority of Ontario (CMRAO).

To verify the name of your licensed condo management service provider, you will have to remove and re-enter the current management company and/or individual by searching either ‘Name’ or ‘Licence Number’ using the new condo management lookup feature.

If you do not have the current management company’s licence number, you can retrieve it by accessing the CMRAO’s Public Registry.


 The CAO’s mandate requires the gathering and reporting of relevant and helpful digital resources to assist condo owners, directors and the broader condo sector.

To assist in creating these resources, it is important for the CAO to gather information regarding Ontario’s condo sector, including the purposes for which units are used (e.g., residential, industrial, commercial).

The “Units” field on the return will provide you with drop-down definitions of unit use options. Please note that the number of different unit types must equal the total number of units.


Throughout the filing process, you will receive validation notifications that alert you to information that may have been missed, filled out incorrectly, or that is different from the information that the CAO has on file.

A validation notification will appear as a pink “Validation Summary” message at the top of your return. Specific fields which may have been completed incorrectly or are different from CAO’s records will appear in red.

If you receive a Validation Summary please review each specific message to determine which part of your return needs to be reviewed and make the applicable changes.


The CAO has provided a number of helpful resources on filing your condo return on its website, including:

We encourage you to please review them. If you are still experiencing difficulty filing your return, the CAO’s Information Services Team are available to assist you. Please note that we are currently experiencing higher than normal call and email volumes, as January 6 to March 31 is returns filing season. If you would like to leave a voicemail, the CAO’s staff will return your call as soon as possible.
