Janet Ajzenstat (born 1936) is professor emeritus of political science at McMaster University.

Her view of Canadian federalism, which dismisses the idea of special status for Quebec or Indigenous people, provoked much scholarly debate, especially following the collapse of the Meech Lake Accord.

[1] Ajzenstat also contends that so-called “judicial activism” undercuts the foundation of responsible government.

[2] As a result, her work is well received by conservative scholars, such as Barry Cooper and Stephen Harper's former chief of staff Ian Brodie.

[citation needed] Ajzenstat received her Doctor of Philosophy degree from the University of Toronto under the supervision of Peter H. Russell.
