Dairy farmers from eastern Ontario took their tractors and cattle to Parliament Hill to protest possible dairy concessions in the soon-to-be-signed Trans-Pacific Partnership.

The farmers rolled down a busy Bank Street in downtown Ottawa on Tuesday, one day before trade ministers from 12 Pacific Rim member countries were set to meet in Atlanta to discuss the TPP.

They also brought cattle.

"OK guys move the cows along" are instructions I don't think Ottawa police give too often. <a href="https://twitter.com/hashtag/TPP?src=hash">#TPP</a> <a href="https://twitter.com/hashtag/cbcott?src=hash">#cbcott</a> <a href="http://t.co/dz8mK5ss6K">pic.twitter.com/dz8mK5ss6K</a> —@amkfoote

Many of the tractors have that familiar "milk cow" logo on them. <a href="https://twitter.com/hashtag/TPP?src=hash">#TPP</a> <a href="https://twitter.com/hashtag/cdnpoli?src=hash">#cdnpoli</a> <a href="https://twitter.com/hashtag/cbcott?src=hash">#cbcott</a> <a href="http://t.co/E58xLZymCK">pic.twitter.com/E58xLZymCK</a> —@amkfoote
