July 11 (Reuters) - Ford Motor F.N said on Saturday it has reached a tentative agreement with Canadian auto union Unifor on a three-year national labor contract.

The contract covers more than 5,000 unionized employees in Canada, the company said.

Here is what to know:

• Ford and Unifor did not immediately respond outside regular business hours to a Reuters request for comment on details of the agreement.

• Unifor began negotiations with Ford last month, commencing talks on new contracts with Detroit's Big Three automakers: Ford, General Motors GM.N and Stellantis STLAM.MI, seeking better pay, job security and benefits for its nearly 19,000 members at those companies.

• The union said last month it had started with Ford because the automaker has been most committed to continuing its operations in Canada.

• The agreement is subject to ratification by Ford-Unifor members.

• Existing collective agreements between Unifor and the automakers expire on September 20.

• The union began talks earlier than usual, citing worsening economic conditions.

• Some 6,000 workers have been laid off across plants owned by the three automakers as the companies have shifted or paused production at several facilities.
