We definitely have small canines compared to other animals, but they are canines. Our dentition is typical of omnivores, as is our gut. But canine size isn't always relevant; the primates with the biggest canines are gorillas. Their diet (it varies by subspecies but is pretty similar) mainly consists of fruit (around 80%), then leaves (15-20%), and the remaining 2% to 3% tends to be insects or grubs. Their enormous canines are for defense and intimidation (evolution via sexual selection) and meat eating isn't a factor.
