The Canola Research Hub features many projects (completed and ongoing) from the Canola Agronomic Research Program (CARP), which is a collaborative research initiative funded by Alberta Canola, SaskCanola, and the Manitoba Canola Growers, and administered by the Canola Council of Canada. Since its establishment in 1985, CARP research has continued focused on helping canola farmers increase yield and profitability, reduce production risks and enhance sustainability.

Research priorities to inform CARP 2023

Although projects selected for CARP 2022 only officially began on April 1st, 2022, preparations are already underway for CARP 2023. Letters of Intent (LOIs) for 2023 CARP are now being accepted by the CCC on behalf of the three prairie canola grower associations until July 18th, 2022. Submission details and contact options are available this Canola Agronomic Research Program page.

To help guide researcher applicants on what is need by these organizations and to prevent any redundancy of projects currently in progress, the organizations involved and the Western Grains Research Foundation (WGRF), which may also be a funding partner for some projects, are sharing their research priorities.

To discover the important areas of focus for these five organizations, which will inform the selection of the CARP 2023 project, see their research priorities:

Crop production research priorities

Explaining the Canola Agronomic Research Program

The Canola Council of Canada’s thorough crop production research priorities, which are updated annually (which prevents any duplication of efforts on topics that received funded over the past year) through consultation with industry, expert steering groups, and the annual Canola Week event are provided below:


  • Determine the economic and production impact of climate change and landscape modification.
  • Model canola’s carbon sequestration potential and investigate areas for improvement.
  • Evaluate and identify alternative management tactics and tools for major canola pests.
  • Understanding the production and environmental risks and benefits of tile drainage systems.
  • Evaluate the economic, environmental, and production feasibility of cover crops to canola production systems.
  • Discover water use efficiency improvements (ex. genetic, agronomic, irrigation management).
  • Evaluate the role of canola’s microbiome in carbon sequestration.

Insect pests

Learn about ongoing insect pest concerns in canola
  • Evaluate and identify alternative management tactics and tools for major canola pests.
  • Technology and strategies to reduce off-target impacts of foliar insecticides and improve their efficacy.
  • Insect pest monitoring and surveillance.


  • Weed monitoring and surveillance, modelling of weed species shifts in a changing climate.
