Confined Research Field Trials for Plants With Novel Traits (PNTs)

What are Plants with Novel Traits (PNTs)?

PNTs are plants with novel traits. These plants have traits which (1) are not present in plants of the same species that already exist in Canada or (2) are expressed outside the normal range of similar existing traits already in the plant species. Details on definitions for PNTs and biotechnology are available in the factsheet "Modern Biotechnology: A Brief Overview".

What are confined research field trials?

In the early stages of PNT development, the plants are grown in fields in a confined area for research purposes. The CFIA's Plant Biosafety Office (PBO) assesses applications for these confined research field trials and sets out the rules for how they are to be done.

No matter what method has been used to put the new trait into the plant, all confined research field trials of PNTs in Canada are evaluated by government scientists to determine that the trials will not harm the environment.

Why do developers of PNTs conduct confined research field trials?

Confined research field trials for PNTs have several purposes. They:

Are there rules for conducting confined research field trials?

Developers must meet strict conditions before conducting a confined research trial in Canada. Developers of PNTs have to provide government evaluators with information about the plants (such as where they are being grown and the procedures being used) and must also work with the CFIA both during the field trial and after harvest. Some other requirements are:

Additional details on requirements for confined research field trials can be found in the "Directive 2000-07 (Dir2000-07): Conducting Confined Research Field Trials of Plants with Novel Traits in Canada".

What if any of these plants pollinate other plants?

Applicants are required to monitor their fields frequently. If related species are found within the trial's isolation zone, the applicant must remove and destroy these plants before seeds are produced. After harvest, any volunteers or related species found in the area that is covered by the post-harvest land use restriction must be removed before flowering occurs. If pollination, hybridization, or seed production do occur, additional post-harvest restrictions and monitoring requirements will be imposed on the trial.

What happens if developers don't follow the rules for confined field trials?

The CFIA has the authority to revoke the authorization for the trial, and the trial may have to be destroyed or other measures taken to bring it into compliance.

What happens to the plant after the research trial is over?

After the confined research field trial, the PNT is destroyed. Nothing that is harvested from a confined field trial may be used as human food or livestock feed.

Unless the CFIA authorizes developers to keep seeds for future research trials, the seeds and other plant material harvested from confined trials must be disposed of by an approved method. Examples include incineration, using superheated steam under high pressure (autoclaving), deep burial, or other means that will make the seed or plant material unable to live. Composting is not allowed as a disposal method.

Does the CFIA limit the number of confined research field trials that are held in Canada?

Yes. The CFIA restricts the size and number of the trials. The CFIA may consider an exception to this but the developer has to give a scientific reason to justify the request, and the reason must be for research purposes only.

Who else reviews the information the applicant submits?

The CFIA's Plant Biosafety Office will distribute copies of received field trial applications to the Agency's livestock feed evaluators (Feed Section), if the applicant wants to use material from the trial in a research feeding study. The PBO also gives information to the Pest Management Regulatory Agency (PMRA) in cases involving testing novel herbicide tolerance or insect resistance.

The CFIA also sends non-confidential information about each new trial to designated provincial government contacts, in those provinces where proposed trials are going to be done. The federal Access to Information Act sets out what information is considered to be "confidential business information."

As well, the CFIA sends non-confidential information on authorized field trials to the BioTrack database of the Organisation of Economic Co-operation and Development (OECD).
