The Canadian Pest Management Regulatory Agency (PMRA) has completed its reevaluation of eight rodenticides and is requiring additional mitigation measures to address concerns about ecological risks and risks to children and pets.  The eight rodenticides are brodifacoum, bromadiolone, bromethalin, chlorophacinone, difethialone, diphacinone, warfarin, and zinc phosphide.  The Executive Summary of PMRA’s decision can be found by clicking here.  With a few exceptions (e.g. the prohibition against using brodifacoum and difethialone outside of a structure), the mitigation measures adopted by PMRA are in-line with the recommendations made by CPMA.
