A government document presented to caucus last summer shows the provincial government knew that queue jumping was taking place in the healthcare system.

Within the 28-page Powerpoint presentation it states: "Alberta doesn't support queue jumping, but only explicitly prevents it in the Health Care Protection Act for non-hospital surgical facilities. Despite this prohibition, queue jumping occurs in many ways."

It goes on to say: "There are gaps in the legislation that allow workarounds."

The document states that while the issue of queue jumping may arise publicly, it will not be reviewed.

The July 12, 2010 document's release comes the same week comments made by the former boss of Alberta Health Services were made public regarding allegations of queue jumping.

Stephen Duckett, spoke at an event at the University of Toronto in May, alleging MLAs helped patients jump the queue.

Duckett says he was told that MLAs had go-to-guys in the system who could slide people up to the top of the list for treatment.

"I'm told my predecessor had designated go-to-guys for discreet waiting room adjustments at the request of MLAs. It's a practice I discontinued," he said.

But the health minister maintains there is no evidence to back up Duckett's claims.

"The document is not a government position, this is a collection of comments, opinions, perceptions and ideas expressed by Albertans to a committee that travelled the province," said Health Minister Gene Zwozdesky.

The minister says the document refers to out of province or out of country queue jumping.

"It's one form of queue jumping to try to access a medically insured service in an other province because you might get it faster," said Zwozdesky.

But critics aren't backing down.

"I think they are trying to mislead you, I think that is absolutely false," said Mason.

The employment minister agrees queue jumping might happen.

"To say that, categorically, it is not happening, I think would be rather naive and out of touch with human nature," said Thomas Lukaszuk.

For months opposition parties have been calling on the government to call a public inquiry into healthcare. And Mason continues to push for that inquiry.

"The question is whether or not MLAs and their family and friends took advantage of it and that's what we think needs to be investigated.

The health minister says Alberta's Healthcare Protection Act prohibits queue jumping and also comes with stiff penalties to anyone who does. He maintains he has no evidence this actually happening.

A day earlier, two PC leadership hopefuls said they would support a review. But Zwozdesky believes it's all a campaign strategy and says it's an attempt by MLAs Alison Redford and Doug Griffiths to separate themselves from other candidates.
