In 2008, the Canadian Home Builders Association commissioned Altus Clayton to write a report that is very critical of Inclusionary Housing. This report has been used as the basis for arguments that municipalities should not use IH policies to try to increase the supply of affordable housing.
The Wellesley Institute commissioned David Rusk, a leading American expert on Inclusionary Housing, to examine this report and look at the counter-arguments in favour of using this tool. Richard Drdla, the leading Canadian expert, has also written a paper that examines the many flaws in the Altus Clayton report.
