Trillium List overview

The Trillium List contains the titles of current textbooks approved by the Minister of Education that educators can use to teach students in Kindergarten to Grade 12 in Ontario’s publicly funded schools.

A textbook on the Trillium List is a comprehensive learning resource. It may consist of a single resource or a package of resources, and may be in print or digital format, or a combination of both. It is intended for use by an entire class or group of students and must pass rigorous evaluation by a team of qualified Ontario-based education experts.

Eligibility requirements, criteria and evaluation process are explained in The Ontario Curriculum Review and Revision Guide.

Regulation 298, “Operation of Schools – General”, made under the Education Act, requires that school principals select textbooks from the Trillium List in consultation with teaching staff, and requires that their selections be subject to the approval of their school board.

In instances where no textbook for a subject or course is included in the Trillium List, principals must consult with teaching staff and decide whether a textbook is required, and if so, select a suitable textbook for evaluation and approval by their school board.

Expiring textbooks for the English-language education system

At the start of each school year, the ministry updates the Trillium List to reflect its decisions to discontinue textbooks. The ministry informs school boards that the textbook will be removed from the Trillium List, that their schools must no longer purchase class sets of the textbook, and that they may continue to use the textbook for up to two more school years as a phase-out period while they decide how to replace it.

After two school years, the outdated textbook is removed from the Trillium List. School boards are responsible for ensuring that expired titles are not used as textbooks.  

The following textbooks are expiring from the Trillium List.
