The purpose of this document is to notify registrants, pesticide regulatory
officials and the Canadian public of Health Canada's Pest Management
Regulatory Agency's (PMRA) decision to initiate a re-evaluation, under
section 16 of the Next link will take you to another Web site Pest Control
Products Act <http://laws.justice.gc.ca/eng/acts/P-9.01/>  (PCPA), of the
nitro-guanidine neonicotinoid insecticides, clothianidin and thiamethoxam,
and their associated products registered in Canada. Currently, another
nitro-guanidine neonicotinoid insecticide, imidacloprid, is under
re-evaluation. The re-evaluation of this cluster of active ingredients, will
focus on resolving issues related to environmental risk; in particular, the
potential for effects of nitro-guanidine neonicotinoids on pollinators in
light of changes in the information required and global updates to the
pollinator risk assessment framework. This re-evaluation will consider all
agricultural uses of nitro-guanidine neonicotinoid insecticides including
soil applications, seed treatment, as well as foliar and greenhouse uses.

There continues to be emerging science on neonicotinoids and their potential
effects on pollinators. The PMRA is collaborating with international
regulatory partners to discuss further data requirements and in the
development of enhanced risk assessment methodologies and risk mitigation
measures for pollinators. 

The PMRA has requested additional data on neonicotinoid insecticides and is
working with international partners to develop additional data requirements
and risk assessment methods. As well, the scientific community continues to
publish additional research results. All new information must be evaluated
to confirm that these products do not pose an unacceptable risk. To
facilitate the evaluation of these chemically similar products, all
nitro-guanidine neonicotinoids, outlined in Table 1
<http://www.hc-sc.gc.ca/cps-spc/pubs/pest/_decisions/rev2012-02/index-eng.ph
p#table1> , are being placed under re-evaluation to ensure a comprehensive
environmental evaluation, including consideration of new scientific evidence
emerging from the research community and to reflect the new methodologies
being developed at the international level.

The PMRA has received reports relating to bee mortalities occurring in
Canada and internationally. Should evidence become available demonstrating
reasonable grounds to believe that health or environmental risks of a
pesticide are unacceptable, the PMRA will take appropriate regulatory
action. 

Health Canada's Pest Management Regulatory Agency is collaborating with our
international regulatory partners to fully evaluate the potential risk to
pollinators from neonicotinoid pesticides. The PMRA is committed to only
registering pest control products that meet stringent health and
environmental standards and do not pose unacceptable risks.
