Toronto Deputy Mayor Doug Holyday continues to insist that a final deal they offered the city's inside workers late last night is a fair offer that will be ratified by the union.

Holyday reiterated his confidence in the offer Monday afternoon, about six hours after union officials announced that for the first time in history, it was taking the city's offer and presenting it to their members without recommendation.

"It leaves workers with one of the best labour agreements in Canada," Holyday told reporters. I feel it will get the support of workers and will be ratified."

But union officials say they're  not making any recommendations on the offer because the city stopped negotiating on outstanding issues.

CUPE Local 79 President Tim Maguire said the city made it clear that the new terms would be imposed on members if they did not accept the deal. He told reporters early Monday morning that although many concessions had been made, there were still four outstanding issues that the city and union were unable to agree on, despite a marathon bargaining session that went two days past Friday's midnight deadline.

At 12:15 a.m. Monday, both sides emerged from the bargaining table to say they would no longer be negotiating the terms of the city's latest contract offer.

Holyday told CP24 that he doesn't know why the union didn't endorse the offer.

"There's politics going on and perhaps there's something going on that we don't understand," he said.

Holyday said the offer is very similar to what was recently offered to the Local 416, the union representing outside workers, especially in terms of job security, wages and benefits. The offer is based on a four-year term.

The city has made it clear it is their final offer and that union members should not expect them to make any changes to it.

Maguire spoke to reporters after Holyday's news conference and said the union was attempting to find common ground on the outstanding matters but that instead, the city chose to end the negotiations.

Union members will have until Wednesday to review the terms of the offer before they vote.

"We've made compromises to control some damages the administration wanted to inflict on workers," Maguire said. "We have committed to our members, committed to negotiating a settlement but the city pulled away."

He said the union will not make a recommendation but is asking all members to give the offer thoughtful consideration.

He said if members decided to reject the offer, he hopes the city will return to the bargaining table rather than impose the conditions or lock-out workers as they would be legally entitled to do.

The union is also in a legal position to strike if it wishes to do so.

"We have the ability to strike but it will be thought about carefully," he said. "Local 79 simply won't strike because we don't have a contract."

"We are committed to our members and to the city," he added.

Local 79 represents about 23,000 inside workers. They include child-care workers, ambulance dispatchers, nurses, janitors, parks and recreation staff.
