Main Article

Figure 1

Heat map of qualitative estimates for all 53 hazards (arranged alphabetically) potentially associated with canine importation into Canada as determined through a qualitative risk assessment with expert consultation, 2023–2024. Estimates from left to right are likelihood of entry, likelihood of canine exposure, likelihood of human exposure, magnitude of impact of exposure for an individual canine, magnitude of impact of exposure for the canine population, magnitude of impact of exposure for an individual human, and magnitude of impact of exposure for the human population. For nonzoonotic hazards, estimates were not provided for human categories and are indicated by blank squares outlined in black. Hazards marked with an asterisk are groupings of agents. Full descriptions of those groups are available in Appendix 2 Table 1.
