Town officials locked out the six members of the International Brotherhood of Electrical Workers last Friday.
A provincial conciliator called the two sides back to the bargaining table and helped them reach a deal on Wednesday and the workers were back on the job on Thursday.
The deal returns wages lost during the lockout and pays out 30 per cent of accumulated sick time upon retirement.
The union had asked for a payout of 100 per cent.
The four-year contract is retroactive to March of last year and runs until March 2017.
