Roundup Ready Canola (RR Canola) is genetically engineered canola (rapeseed) that has had its DNA modified to withstand the herbicide glyphosate (the active ingredient in Monsanto's herbicide Roundup). It is sometimes referred to as "glyphosate tolerant canola" or "glyphosate tolerant rapeseed." (Canola is a variety of rapeseed.) Roundup Ready Canola was introduced in Canada, one of the world's largest producers of canola, before it was introduced in the United States.
