You need to get an Alberta WIN card first, then your brother has to get a hunter host licence which includes your WIN identification number.
Then you can buy your own non-draw licences.

All hunters must have a Wildlife Identification Number (WIN) as a prerequisite to applying for, or purchasing any hunting licence.
Non-resident and non-resident alien hunters (12 years of age or older) are exempt from the first-time hunter eligibility requirement if they are accompanied by a Hunter Host or a Designated Guide while hunting in Alberta.
Wildlife Identification Number (WIN)
Hunters and anglers in Alberta must possess a 10-digit Wildlife Identification Number (WIN) before applying for or purchasing any licence or wildlife certificate. The WiN can be purchased for $8.00 and is valid for five years
If you are purchasing a WIN for the first time you can purchase one online at albertarelm.com or at a licence issuer. The licence issuer gives you a paper receipt (which includes your new number) allowing you to purchase licences immediately. Your plastic card will be mailed to you within a few weeks.
If you have any questions about the WIN or the licensing system, please contact the RELM Call Centre, toll-free in North America, at 1-888-944-5494.

Hunter Host Licence
A resident who wishes to be a Hunter Host may purchase a Hunter Host Licence at any private licence issuer. You must have the WIN(s) of the non-resident(s) at the time of purchase. You must ensure that the hunters you host are named on your Hunter Host Licence. If you purchase your Hunter Host licence naming one hunter and you decide to add a second hunter to your licence at a later date, you can do so at no additional charge. Return to a private licence issuer with your licence and have it amended. Once you have purchased your Hunter Host Licence, the hunters may purchase their licences.
