The CAP's Educational Trust Fund (ETF) is a tax exempt fund which supports the many activities undertaken by the CAP in support of physics education and physics student activities. The fund derives all of its income from Individual and Corporate Member donations. The fund is administered by a board of three trustees appointed by the CAP Executive.

The ETF supports a wide range of activities to encourage excellent young physics students across the country, including:

• the annual CAP Lecture Tour, in which outstanding speakers from the CAP membership are supported jointly by the CAP and by host university departments to deliver special physics lectures to undergraduate students at Canadian universities between January and April of each year;
• the High School Prize Examination, in which approximately 700 high school students from across Canada compete each year for cash prizes and award certificates at the regional and national levels;
• the Lloyd G. Elliott University Prize Examination, in which approximately 100 students from across Canada compete each year for cash prizes and award certificates; the first prize winner is supported to attend the CAP's Annual Congress to accept his/her prize at the congress banquet;
• the Canadian Undergraduate Physics Conference, which is hosted each fall at a Canadian university -- the CAP's ETF provides a contribution to travel support for students to attend the conference;
• the Canada-Wide Science Fair, the Virtual Science Fair, and the Canadian Physics Olympiad, for which the CAP's ETF provides cash prizes and award certificates..
