The price tag for this year's federal election is expected to spike by nearly a third, partly because of big changes to Canada's electoral map.

The 2015 election will see 30 new ridings and boundaries redrawn in 70 per cent of the others. Running the election will cost a projected $375 million — up more than 28 per cent from the $292 million spent on the 2011 election, according to figures provided to CBC News by Elections Canada.

The election in 2008 came in at $286 million.

Preparation costs for this year's vote are pegged at $55 million — including $18 million in extra costs related to riding redistribution.

That envelope includes information technology systems and infrastructure; maps and voter lists; training for returning officers and field and special events staff. It also covers the design of a new advertising campaign and other communication products.

According to Elections Canada, a 6.9 per cent increase in inflation and a 4.5 per cent growth in the number of voters in the last four years are also driving up costs. A spike in postage costs — an estimated increase in $5.7 million — and legislative changes that include an extra day of advance voting will also add to the bottom line.

Elections Canada estimates that the delivery of the election will cost $253 million — that includes fees for polling staff and sites and communications, as well as local and centralized support.

Add to that the reimbursement for election expenses to political parties and candidates, along with audit costs, that will add another $67 million to the total cost.
