Confusion over when the peak tourism season ends on P.E.I. has cost the P.E.I. Jazz and Blues Festival up to $30,000 in funding from Ottawa's regional development agency.

'It just didn't occur to us that ACOA would have a different peak season.'— Doug Millington, P.E.I Jazz and Blues Festival

Organizers of the week-long music festival moved it to August for the first time this year. Festival chair Doug Millington told CBC News Monday the Aug. 15 start date qualified for provincial funding, because the province considers that outside the peak tourism season.

But ACOA, the federal funding agency, doesn't consider the peak season over until the end of August.

"It was not good news when it happened, let me put it that way. We rolled with it, and we accepted the responsibility for the miscommunication," said Millington.

"It just didn't occur to us that ACOA would have a different peak season. And they have very strict guidelines on what they're going to fund and what they aren't going to fund, especially when the federal government is desperate to cut costs wherever they can."

Millington said the loss of money meant a lot of cost-cutting, including a significant reduction in off-Island advertising.

The P.E.I. Jazz and Blues Festival runs from Aug. 15-21.
