A strike would also impact employees at airports and marine ports of entry.
The clock is ticking down to an afternoon deadline for a new deal between the Public Service Alliance of Canada and the federal government.
There could be massive disruptions at Niagara's and the rest of Canada's borders if a strike by border workers goes ahead later today.
The two sides went into mediation on Monday but Canada Border Services Agency employees are set to begin job action at 4 p-m today if there's no deal before then.
The government says 90 per cent of CBSA front-line workers are deemed essential and cannot strike.
But union members could work-to-rule, slowing the flow of border traffic by doing their jobs exactly as outlined in their contracts.
A strike would also include employees at airports and marine ports of entry.
