With all the drug-related violence and craziness along the Mexican-U.S. border, we seldom hear much about  the Canada-U.S. border.

The Toronto Star reports that the “hardening of the Canada-U.S. border” has resulted in a fourfold increase in marijuana seizures.

U.S. authorities seized 17,915 kilos of Canadian-grown marijuana during the year ending Sept. 30, compared to 4,325 kilos the previous year, according to figures to be released Friday by the U.S. Customs and Border Patrol, the paper reported.

The paper said U.S. border officials attributed increased seizures to better cross-border police cooperation and new technology including unmanned aerial drones.
