The initial inspection station was established at Killarney about 21 kilometres (13 mi) north of the present crossing.

Under the administrative oversight of the Port of Winnipeg, the office handled goods received by road.

Inconveniently located and vulnerable to smuggling, the office moved to the border in 1930, adopting the name of Lena, the nearest post office.

[citation needed] In 2020, the former border hours of 8am–9pm reduced, becoming 8am–4pm.
