The groups met with Transport Minister Lisa Raitt last week to discuss what they call the dire situation facing grain farmers.
Doug Chorney of Manitoba's Keystone Agricultural Producers says they told Raitt that Ottawa should fine grain shippers that don't meet their commitments.
The groups also suggested the government should toughen and enforce rules that pertain to railways.
Norm Hall, president of the Agricultural Producers Association of Saskatchewan, says the grain backlog means Canada is losing markets and prices are falling.
The groups, including the Alberta Federation of Agriculture, warn the backlog is so bad that some farmers won't have enough cash to pay for seeding this year's crop.
