For professors and students: Preparing to do research at the Archives of Ontario

Before doing research at the Archives, you should prepare by doing the following:

  • Determine what you will be researching and narrow your research topic – the more precise it is, the better the chances are that you will find the records you need.

  • Consult secondary sources about your topic, such as books, periodicals or e-articles. They will help you understand what you are looking for, and they may include references to relevant archival materials. Your university library is the best place to look for these sources.

  • Think about who may have created the records you need, why they would have created them and how they would have created them.

  • Find what archival repository has the records you need. Many municipalities, the federal government and your own university have their own archives. Some may be more suitable for your needs than others.

Also, keep the following in mind:
  • Archival records are records OF, not ABOUT, governments, organizations and people. They are arranged by creator (who created them), not by subject.

  • Most archival records are not available online. See below for information about accessing and retrieving records.

Accessing and using archival records


Ordering records and getting copies: Once you have identified records (or groups of records) you want to view, you can arrange to view the records and to get copies of them. For more information, click here.

Using the records: Our staff will show you how to handle the records, and provide you with gloves, weights, supports and other tools to help you use the records safely. Make sure to note carefully what you see and will be using, its reference code, title and container. You will need this information to order copies and to provide citations for your project report or paper.

Access to some records may be restricted under privacy legislation or donor agreement, or because of preservation issues. These records take longer to access. Please give yourself enough time to access these records, especially if you have a deadline to complete a project or paper. You can consult our reference staff for more information.
