How To Apply For Confined or Unconfined Release of PNTs
|
| A confined research field trial is the release of a plant with novel traits (PNT), for
research purposes, under terms and conditions of confinement designed to minimize any
impact the PNT may have on the environment. In Canada, confined field trials for research
on PNTs provide developers with the opportunity to evaluate the performance of PNTs, study
the environmental safety of these modified plants, address the criteria and information
requirements considered in the environmental safety assessment of PNTs for unconfined
releases and generate data for variety registration purposes. Instructions, information
requirements, and terms and conditions can be found in the following:

| The Plant Biosafety Office of the Canadian Food Inspection Agency is responsible for
the regulation of plants with novel traits (PNTs) in Canada in regards to environmental
safety. Before a PNT can be authorized for unconfined environmental release, a
determination on the risk to the environment, including to human health, is required.
Unconfined release involves the release into the environment with limited or no
restrictions, generally towards commercialisation. The following documents define the
criteria and information requirements for the environmental safety assessment of a PNT
intended for unconfined release:
