Heat the wood charcoal* or other grill to medium heat, about 400°F. Brush the grill grates with oil to prevent sticking.
Thread 6 shrimp on each skewer. Lightly season with salt. Mix the canola oil and jerk seasoning in a small bowl. Brush the mix on both sides of the shrimp.
Place the skewered shrimp on the grill and cook for 3 minutes per side until the shrimp are opaque.
If desired, squeeze some fresh lime juice on the shrimp and garnish with fresh chopped cilantro.
* Use pimento wood if available. If not, you can use a 50/50 blend of cherry and hickory to achieve a similar taste.
