I think there are a couple of policy responses to that question.
First, we do know that directly involving persons with disabilities in the decisions that affect them will affect that culture change. Having them involved in an organization where they are informing the development of accessibility plans and informing how that organization thinks about persons with disabilities—both employees with disabilities and customers or citizens with disabilities—will change the conversation about how that organization approaches that customer base or those employees.
From a policy perspective, having persons with disabilities involved in governing the Canadian accessibility standards development organization and being involved in technical committees for standards development, again, will change the conversation about those issues that affect the lives of persons with disabilities.
Do I think legislation is the only silver bullet for changing the conversation? That's not what I'm saying. There are lots of other things that can and should be done in terms of that culture change.
