Toronto's inside workers voted on the city's final contract offer on Wednesday but by early Thursday morning, union officials had still not said if members voted to accept the proposal or if they were choosing to strike.

Union officials remained at the Sheraton hotel in downtown Toronto Wednesday night, discussing the vote, the contract offer and their options going forward.

However, by 1 a.m. Thursday, reporters waiting for an update were still in the dark about the union's next move.

Earlier on Wednesday, CUPE Local 79 President Tim Maguire said there was a ‘very real' possibility that Toronto's 23,000 inside workers would vote against a final offer from the city and walk off the job.

"This city has indicated that if these contracts are not ratified [Wednesday], they will impose these terms or worse [Thursday] morning and it's disheartening," Maguire said. "We have a very real possibility of a strike here and the city should really consider whether it wants to go down that road."

After a marathon weekend of negotiations in which talks twice went well into the early morning hours, the city tabled their 'final offer' Sunday evening.

Four separate bargaining units each had an opportunity to make their own decision, so the possibility that only a segment of CUPE 79 may walk off the job does exist, Maguire said.

Voting closed at 8 p.m.

"It's up to (members) to decide," Maguire said earlier on Wednesday. "We are providing all of the information in terms of what's in those offers and the context of bargaining with the employer."

If all or part of CUPE Local 79 votes against the offer and the city follows through with its threat to impose conditions workers would not walk off the job on Thursday, Maguire added.

"We would not strike tomorrow," he said. "We would take a considered, thoughtful view in terms of when and what we would do."

Deputy Mayor Doug Holyday told CP24 he was hopeful workers would accept the deal.

Some of the highlights of the deal include a 4.5 per cent wage increase over four years and an increase in the number of years seniority required to keep your job in the event of privatization from 10 to 15.

"It is fair to the workers and it's fair to the taxpayers," Holyday said. "We achieve certain management rights back that we need to be more efficient and they get a modest pay increase."

CUPE Local 79 represents nurses, janitors, ambulance dispatchers, recreation workers, child-care workers and urban planners.

If the union does walk off the job, the city says daycares, pools, arenas and community centres would be closed as would museums, art galleries and cultural facilities run by the city.

Emergency services would not be impacted.
