Season pork with 1 teaspoon salt and ½ teaspoon pepper.
Heat canola oil in a large skillet over medium high heat. Add pork, onion, garlic, chili powder and cumin. Cook, stirring often, until pork has browned, about 8-10 minutes.
Stir in orange juice and lime juice, scraping any browned bits from the bottom of the skillet. Cook until reduced, about 2 minutes. Remove from heat; season with salt and pepper, to taste.
Serve immediately.
