In the May 5 vote, Tory Linda Johnson and NDP Anam Kazim ended the night tied with 7,015 votes in the riding of Calgary Glenmore.
Elections Alberta's official recount found Kazim edged Johnson, who was the incumbent.
Johnson says there are a significant number of ballots in which the voter’s intention could be in question.
She says they may have been counted differently by the deputy returning officer on election night, and the returning officer in the official count.
Johnson says she is filing the application today, and it must occur within 10 days.
The NDP have 53 seats, Wildrose 21, PC's have nine, the Alberta Party and Alberta Liberals each have one; there's one Independent and one vacant seat.
