In Canada, in the case of a brokerage (independent business that can sell products from a number of different insurance companies) usually 60% of the 1st year's premium goes to the insurance brokerage (business that the aggent works for) and then the agent may get 60% of that .
If a brokerage does enough volume, they may qualify for a "bonus" from the insurance company and the agent may receive a portion of this too, upon the descretion of the brokerage.
