Preheat the oven to 350 degrees F. Grease a 2-quart casserole dish with the canola spray.
In a large bowl, mix together the milk, onions, sugar, butter, salt, pepper, crackers, corn, cream-style corn and eggs. Pour into the prepared casserole dish and bake uncovered for 1 hour, stirring halfway through.
