Mayor David Miller has been invited to address a kick-off to the annual Labour Day parade, though he’s not welcome to march in the parade itself.

Miller will speak to a crowd of Canadian Auto Workers — which will benefit from the city’s billion-dollar purchase of streetcars and subway cars from Bombardier — but he won’t join the CAW members as they march with other unions to the CNE grounds.

That’s because another labour group, the Toronto and York Region Labour Council, is unhappy with the mayor’s handling of the bitter 39-day municipal workers’ strike by some 30,000 members of the Canadian Union of Public Employees.

The labour council organizes the parade and is entitled to invite or not invite whoever it wishes, said Peggy Nash, who is assistant to CAW national president Ken Lewenza.

The CAW appreciates Miller’s support for awarding a $1.25-billion streetcar order to Bombardier’s Thunder Bay plant earlier this year, Nash said. In 2006, the city also gave a $710-million subway car order to the Thunder Bay facility.
