LONDON, Ont. -- Production and skilled trades workers at the General Motors assembly plant in Ingersoll, Ont. -- known a the CAMI plant -- have reached a tentative contract settlement with the automaker.

The 2,700 workers are members of Unifor, the new union created by the merger of the Canadian Auto Workers with the Communications, Energy and Paperworkers union.

Unifor announced the agreement in a release Saturday morning that said the tentative deal was negotiated late Friday.

Details of the agreement are being withheld pending the results of a ratification vote on Sunday.

The results of the vote are expected to be released Sunday evening.

The CAMI workers are represented by Unifor Local 88, and manufacture the Chevrolet Equinox and GMC Terrain vehicles.

Union bargaining committee chair Mike Van Boekel said he expects the proposed deal will be approved by union members.

"I am extremely confident that it will pass."
