LONDON, Ont. Management and workers at one of London, Ont.,s largest employers have reached an eleventh-hour tentative deal.

Negotiators with the Canadian Auto Workers unio and General Dynamics came to an agreement just hours before Sundays midnight strike deadline.

Details of the proposal will remain under wraps until some 600 unio members vote on it Tuesday.

General Dynamics employs nearly 2,400 people at the plant (on Oxford Street East), and roughly a quarter of them are members of the CAW.

The defence and aerospace builder recently received a $1.1 billion contract to upgrade a light armoured vehicle fleet for the Canadian Forces, as well as $200 million in contracts from the U.S. Marines.
