It may be a while until garbage pick-up is privatized across city, the Toronto Star reports.

Speaking to that newspaper's editorial board, Deputy Mayor Doug Holyday says a clause in the city's current contract with the union representing garbage collectors ensures that workers with 10 years' seniority can't lose their job if work is contracted or privatized.

The contract with CUPE Local 416 expires in 2012.

But Holyday also tells the Star that attrition will slowly thin the ranks of those workers.

Even then, there is nothing to stop the city from growing the territory of the contract for private garbage pick-up in Etobicoke.

Holyday says that could prompt CUPE to start competing by becoming more efficient and productive.
