The Canadian economy’s recent growth spurt ran out of steam in October, starting off what many expect will be a weak end to this year and slower growth in 2012.

Real gross domestic product came in flat during the month, even below the extremely modest 0.1% consensus expectation of economists.

The result ends four consecutive months of relatively strong growth that helped push gross domestic product up 3.3% in the three-month period ended Sept. 30, the second strongest quarter in almost two years.

“A not so cheerful start to the holiday season,” said CIBC World Markets economist Peter Buchanan.

“The (result) fell short of both our own and the street’s forecast … some observers may have expected an above-consensus figure for monthly GDP after the better-than-expected monthly retail figures released earlier in the week.”

Retail sales were up, as was manufacturing, but weak returns from utilities, construction, mining and oil and gas, and wholesale trade wiped out the gains.

Scotiabank economist Derek Holt said the result suggests that fourth-quarter growth, which includes still unpublished data from November and December, is tracking at a soft 1.4% annualized rate. That’s better than the Bank of Canada’s official call, but would constitute a disappointment.

The output growth fluctuations for the year roughly track what the central bank and economists have been anticipating.

A strong start to 2011 in the first quarter gave way to the shock of the Japanese earthquake disruptions in the spring, which knocked down growth in the second quarter, followed by a rebound in the summer months.

The fourth quarter, which ends Dec. 31, appears to be reflecting underlying soft conditions.

In a note Friday, TD Bank economists said Canadians should brace for weakness to carry over to the first half of 2012 as well, given the uncertainty in the global economy, led by a Europe already in recession.

“Canada will not be able to escape unscathed from these near-term headlines,” the bank said. “The Canadian economy will be impacted directly through a slowdown in the U.S. economy, as well as a significant pullback in commodity prices during the first half of next year.”

None of the major banks are projecting outright contraction in economic activity, but most stress a full-blown European financial crisis could set off a second global slump.
