Recent growth in wind energy projects in Canada could be undermined if a big federal tax break is not renewed when it expires next spring, industry watchers say.

After a shot in the arm for the industry last week, when Ontario announced more than 600 direct jobs would be created with the opening of two new wind turbine parts factories next year, the sector's main lobby group hopes that incentives for the industry will continue to flow.

They're concerned because the $1.48-billion federal ecoENERGY for Renewable Power program, which gives companies one cent per kilowatt hour as an incentive for renewable energy projects, is set to end in March.

The Canadian Wind Energy Association has lobbied the federal government to extend the incentive program past the March deadline, but says it believes Ottawa is unlikely to do so.
