The Audit Bureau of Circulation’s fall newspaper circulation report is out, for the six-month period ending Sept. 30, 2010, revealing a turbulent newspaper market with many ups and downs.

The Globe and Mail posted a healthy year-over-year gain, increasing its Monday to Friday circulation by 3.85%, moving from 301,767 to 313,378 paid copies. The Globe was also one of the few dailies to post an increase from the ABC spring newspaper circulation report (ending March 31, 2010), adding 13,449 copies to its tally.

Canada’s only other national daily, the National Post, posted a YOY decline of 2.28% over its fall 2009 paid circulation, after a significant increase in its YOY this spring.

Vancouver’s hot daily newspaper market saw the Sun post a 3.88% YOY increase (although it dropped a little over 15,000 copies from its spring circ) while its competitor, the Province, saw a minor 1.56% decline over the same period last year.

Working east, Postmedia’s picture gets brighter, as the Calgary Herald posted the biggest increase in the report, climbing almost 10% in its YOY circ, from 119,134 in fall 2009 to 130,405 in fall 2010. Its northern sister pub, the Edmonton Journal, didn’t fare as well, posting a decline of almost 7% over 2009 and continuing its slide from the spring ABC report, in which it posted a YOY loss of 11%.

Montreal’s competitive daily newspaper market also shifted slightly, with the Montreal Gazette moving from a relatively flat year-over-year picture in the spring (with a 1.82% drop) to an all-out slide this fall with a 7.67% decline over its fall 2009 Monday-to-Friday average. Market competitor La Presse kept the status quo, posting a less-than-1% gain over 2009 and reporting only slightly fewer paid copies out on the street than in the spring of 2010. Although its total paid circ is modest, French-language daily Le Devoir posted a tidy increase of 9% over its fall 2009 circ, rising to 28,470 from 26,099.
