The Guardian Club brought attention to the issues of racism and discrimination in Windsor and region. Initially the group encountered the popular belief that such problems did not exist in the area. The group proved their point through a series of ‘test cases’. To test the issue of discrimination in housing on the basis of race an African Canadian couple would attend an appointment to view a house or apartment. The group would then have a ‘control’ white couple, with equivalent qualifications, view the property. In comparing the test cases it was apparent that many equally qualified African Canadian candidates were being told the property was no longer available while their white colleagues who followed them were offered the rental. These tests received a great deal of publicity in the local media at the time.

The Guardian Club was very successful in promoting awareness of these issues and acting as an advocate on behalf of community members who experienced discrimination. The Guardian Club later evolved into the Windsor Human Rights Association and was a precursor of The Windsor and District Black Coalition.
