Assessment rationale/justification
The size of this population was reduced by whaling during much of the 20th Century. However, sightings remain relatively common off Atlantic Canada and they have not been hunted since 1971. The current abundance and level of depletion compared with pre-whaling numbers are uncertain. The whales face a number of current threats including ship strikes and entanglement in fishing gear, but none is believed to seriously threaten the population.; La pêche à la baleine a réduit la taille de cette population pendant une grande partie du XXe siècle. Cependant, l'espèce est aperçue de façon relativement fréquente au large du Canada atlantique et n'est pas chassée depuis 1971. Son abondance et son niveau d'appauvrissement actuels comparativement aux niveaux qui existaient avant le début de la pêche à la baleine sont incertains. Les rorquals sont confrontés à un certain nombre de menaces, dont les collisions avec des navires et l'enchevêtrement dans des engins de pêche, mais aucune de ces dernières ne semblent menacer gravement la population.
