The HMD Project was sponsored by the Hidden Mobility Disabilities Alliance (HMDA) and was a collaboration of organizations, researchers, and experts in the disability field.  See the HMDA website at for more information on HMDA. 

HMDA’s primary partner for this project was the Ontario Disability Employment Network (ODEN) which coordinated project participation by organizations and individuals. Other partners included Berkowitz & Associates (for statistical analysis of the survey results), Performance Plus Rehabilitative Care Inc. (to ensure that French translation was accurate), Service-Growth Consultants Inc. (for project management), and Wiser Projects (for key informant interviews and analysis of accessibility standards).
