So you think that the NDP closed mental hospitals and Lieberals open others? That the NDP abandoned the mentally ill? Think again.
The BC Mental Health services tells a much different story.

And so does the inclusions bc web site. Please take the time to read the history all the way from the 1950s to the 1990s. Speaking about Glendale and Woodlands, "In the fall of 1981 the Provincial Cabinet announced that the institutions of Woodlands, Glendale and Tranquille would be phased out within the following ten years." This is in the 1980 link.

The Self-Advocate site also gives an interesting picture

An effort was made to switching from large mental institutions to community based care. The Socreds started it, then NDP made it happen, and then Gordon Campbell destroyed it by repeatedly cutting funding to mental health care services.
More to come.
