Winnipeg: Western Canadian farmers still stuck with last year’s harvest are turning to the government for credit help in record numbers, and insiders fear problems could cascade through the agricultural economy as the new planting season gets under way. A record-breaking harvest and harsh winter last year overwhelmed Canada’s two big railways, backing up the flow of grain from western elevators to ports and leaving farmers with few buyers. Up to C$20 billion ($18.1 billion) worth of crops was stuck in storage as of late March, according to the Canadian government.
