According to advocate Lembi Buchanan of Victoria, "It has become virtually impossible for the majority of people living with severe psychiatric illnesses to access the DTC without appealing to the Tax Court of Canada."

Those involved in the mental health "Recovery Movement" believe the patient is the expert on treatment rather than the doctor and that there is no need for clinical evaluation or evidence-based treatment. This model does not accommodate the needs of individuals with severe mental illness who may lack insight into their illness and are unable to make appropriate treatment choices.
