Canada has benefitted from international joint reviews and worksharing in the evaluation of new agricultural chemicals - in terms of efficiency, alignment of policies and approaches, similar time access to new technologies, international standard setting reducing trade irritants, and contributing to and using the best science available globally. An emerging challenge facing Canada in terms of pesticide regulation is the statutory obligation to reassess older chemicals on a cyclical basis (ie every 15 years). Unlike pre-market approval processes which benefit from a high level of globally aligned, prescribed data and information requirements (at least among OECD countries), post market re-evaluations face often unique challenges. These  include managing a high volume of of often contradictory evidence, the demand from stakeholders for a high level of engagement and risk communications, and the economic implications that are inherent in regulatory decisions involving potentially high value agricultural chemicals. Building on lessons learned from international joint reviews for new agricultural chemicals, there is also an opportunity to explore postmarket opportunities for greater alignment and worksharing.
