The NDP and the Wildrose say it's important to confirm that the $300,000 from billionaire Daryl Katz, his family and business associates did not all come from Katz himself.
The maximum any one person or group can contribute is $30,000.
Elections Alberta says it can act on complaints and has the power to compel documents and issue fines where appropriate.

A Tory party spokesman has declined to give specifics on the Katz donation, but says there are documents to prove no laws were broken.
