Donaldson was born inOttawa in 1962, and has lived most of her life in Eastern Ontario. She currently lives inKingston, Ontario with her husband,Will Kymlicka.^[1]

Donaldson is a philosopher ofanimal rights. She published a vegan cookbook,Foods That Don't Bite Back, in 2003. She has also co-authored numerous articles in peer-reviewedacademic journals on the topic of animal rights.In 2004, she published ayoung adult novel,Threads of Deceit, under the name Susan Cliffe. This monograph is ahistorical fiction andmystery novel set in nineteenth centuryUpper Canada.

She publishedZoopolis: A Political Theory of Animal Rights, co-written withWill Kymlicka, in 2011. In this book, as well as their other co-authored work onanimal ethics, Donaldson and Kymlicka argue for a group-differentiated political conception of animal rights. Drawing uponcitizenship theory, they argue that although all animals should be protected by the same fundamental rights, individual animals should have different rights (and different responsibilities) depending on their group membership. Animals who form a part of mixed human/animal society (domesticated animals) should be conceived of ascitizens, while animals who are reliant upon the mixed society without being a part of it (liminal animals) should be conceived of asdenizens.Wild animals, who live wholly or mostly separately from the mixed human/animal society, should be conceived of assovereign over their own territory. Intervention to reducewild animal suffering would accordingly be acceptable if compatible with respect for theirsovereignty.^[2]

In 2013, she won theCanadian Philosophical Association's Book Prize, with Will Kymlicka, for their bookZoopolis.^[3]
