FARMERS PAY PRICE FOR POLITICAL FAILINGS

   Canola farmers whose livelihoods have been targeted by China in its feud with Canada say it's time for the federal government to be aggressive at the political level in its fight against a growing number of agricultural trade barriers around the world.
   Several producers told two parliamentary committees Tuesday that China's recent rejection of Canadian canola-seed shipments is only the latest trade disruption that's hurt the country's agriculture sector.
  They reminded MPs in Ottawa about a number of major trade obstacles faced by Canadian agricultural exporters in faraway markets like India, Italy, Vietnam and Saudi Arabia.
