so I want to give a bit of a preface to this post. Remember that I live in the Canadian province of Alberta. There is an organization that call themselves the Alberta Committee of Citizens with Disabilities (ACCD). They produced very good video about barrier free health and medical services (see link below).
At a personal level I have been very fortunate in this regard. In fact, when my GP was building her new offices, she consulted me for recommendations to make the new building as barrier-free as possible. She went to great lengths to accommodate her patients' with disabilities.
But that is one doctor and one facility. Unfortunately, that is not the case for all people with disabilities. Because of this, the ACCD produced the following video that is universal in its application. Well done! See it at the following link.
