OTTAWA -- A dispute involving name tags has sparked a slowdown at the Ambassador Bridge border crossing in Windsor, Ont., and at the Blue Water Bridge crossing at Sarnia, Ont.

The Canada Border Services Agency says the disruption is the result of work refusals by several officers at those ports of entry.

The CBSA says the border staff taking part in the job action are questioning the health and safety implications of wearing a name tag on their uniform.

The agency says name tags are in line with similar polices in place in the Canadian Forces, Correctional Service Canada and United States Customs and Border Protection, whose frontline uniformed officers all wear name tags.

The CBSA says in a statement that management will closely monitor border traffic and try to resolve any unwarranted delays, adding that any illegal actions and inappropriate behaviour "will be dealt with accordingly."

The CBSA says it encourage travellers to consult border wait times on the CBSA website.
