TORONTO - The union representing about 20,000 inside municipal workers in Toronto says it has accepted a tentative four-year contract with the city.

CUPE Local 79 president Tom Maguire says the union is recommending its members accept the deal when it goes to a vote.

No details of the agreement will be revealed until after the voting takes place.

The union says part-time staff at the city's 10 long-term care facilities will have their contract sent to arbitration due to outstanding issues. Those workers do not have the right to strike.

On Monday, Mayor John Tory said the city had issued what it called a "final offer" which Maguire rejected by saying it would create a "two-tier" system for contracting out public services.

The city posted highlights of its offer online, which included protections against contracting out for some workers in addition to a five per cent raise over four years.

The city had settled with its 5,400 outside workers last month.
