A dispute over name tags led to service disruptions at the Emerson border crossing Thursday.
The Canada Border Services Agency said several officers refused to work because of safety concerns over a new policy requiring them to wear name tags on their uniforms.
The officers say it's a security risk.
Yesterday, officers at two Ontario bridges refused to work, causing delays there.
Public Safety Minister Vic Toews' office said the name tags are meant to provide transparency to the public.
