The Canadian economy contracted in April as it shrank by 0.2 percent from March. The April shrinkage was the first monthly decline since the events of Sept. 11, 2001, Statistics Canada reported Friday.

During April, manufacturing output continued to fall, while the economic impact from the outbreak of severe acute respiratory syndrome affected Canada's hospitality sector.

The economic contraction—Canada's first in 18 months—was not unexpected as it matched the forecasts of most economists.

Consumer demand, a key factor to economic health, had been rolling along during the most recent economic expansion as Canadians snapped up houses and new vehicles. However that roll came to a stop in April.

"A number of special domestic and international factors stalled this demand, which resulted in lower output for residential construction and the retailing industry," Statistics Canada said. "There was a retrenchment in the travel-related industries, as both Canadians and international tourists stayed home."

Statistics Canada said it was impossible to isolate the total impact of SARS on the economy.

"The war in Iraq, a weaker-than-expected US economy, a stronger Canadian dollar, fluctuating crude oil prices and other events had inter-related effects in some industries," Statistics Canada said.

Factoring out the travel sector, economic activity declined by 0.1 percent, just a bit better than the whole picture for April.

Manufacturing output fell by 0.3 percent—the sector's second drop over the last three months. Durable goods manufacturers were responsible for much of the weakness.
