Heat 2 teaspoons of the canola oil in a large saucepan set over medium heat. Add the onions and cook until translucent, about 5 minutes.
Add the oregano and cumin, and cook, stirring, for 30 seconds. Add the garlic and cook for additional 30 seconds.
Increase the meat to medium-high, then add the chicken breasts pieces. Cook, stirring occasionally, until the chicken is just cooked through.
Push some of the chicken aside to make a space in the middle, and pour in the remaining 1 teaspoon of canola oil. Add the cornstarch, then stir into the chicken, cooking for 1 minute.
Add the corn, green chiles, chipotle pepper, adobo sauce and chicken broth, and stir to combine.
In a medium-sized bowl, smash 1 ½ cups of the white beans with the back of a fork. Add the smashed beans to the chili.
Bring the mixture to a boil, then reduce the heat and simmer, uncovered, for 30 minutes.
Add the remaining whole beans and the lime juice to the chili. Simmer for additional 10 minutes, or until the chili is thick.
Adjust seasonings (salt and pepper) as desired. Stir in cilantro. Serve.
