Officials from U.S. states and Canadian provinces surrounding the Great Lakes are calling for a closer look at plans to transport crude oil from Alberta through the region.

The Great Lakes Commission has instructed staff to launch a one-year study of the environmental and economic implications of plans to move more oil over and around the lakes by pipeline, rail cars and ships.

Oil transport is increasing as more is produced in the U.S. Great Plains and the Alberta oil sands area in Canada.

The commission says the Lac-Megantic disaster last July shows the risks of transporting oil, as does the rupture of a oil pipeline into Michigan's Kalamazoo River in 2010.
