The Wildrose Party says new automated phone messages from the Alberta Progressive Conservatives are negative and deceitful.
"If somebody says they're voting Wildrose they're then presented with four lies about the Wildrose platform and asked for their opinion on them," said Vitor Marciano, Wildrose senate candidate and former executive director of the party.
"That's just improper. That's not how politics should be done."
The voice on the call first asks the respondent to state whether they support the Wildrose Party.
Respondents are then asked to agree or disagree with a number of statements, including "I agree with Danielle Smith that people should be allowed to drink and drive right up to criminal impairment without consequence."
The tone of the statements have prompted some to characterize the calls as so-called "push polls."
"It's not a survey at all," said Colin Babiuk, the chair of Grant MacEwan University's Public Relations Program. "The whole purpose behind the push poll is to shape perception and opinion and turn it in your favour."
Progressive Conservative Leader Alison Redford denies the calls are push polls. Instead, she says, they help "contrast policies" between the parties.
"Now some people will think that that is a good thing to do and others won't," she told reporters in Fort McMurray.
"I believe that in the next 26 days it's going to be important to contrast policies to make sure that Albertans clearly understand what their choices are."
Robocalls also used by Wildrose
Babiuk says people should get more information before they cast a ballot and not just base their opinion on what they hear in the call.
"I think the public should really look at it for what it is," he said.
"Being aware what push polls are, what the purpose is and then they should be looking at the information, they should be researching the candidates and their platforms and not just taking things for granted."
The Wildrose Party was accused last fall of using push polling techniques in automated calls about Redford shortly after she became Alberta premier.
Smith said Wednesday that her party uses the calls in a way that differs from the Tories.
"We use all of the tools of technology available to us," she said.
"The automatic dialing is a way for us to be able to tell people about events; it's a way for us to do some polling; it's a way for us to directly connect with constituents; it's a way for us to be able to do our telephone town halls."
