The way the Workers' Compensation Board collects its revenues is through the employers, not the employees. So, the employer would be assessed based on his payroll. If you have client "A" from Edmonton who is working in Lupin and earning his wages there, the WCB would assess Lupin Mine based upon the payroll of that particular individual.
