Driver's licenses in Canada are regulated at the provincial level, and regulations vary between provinces. In most provinces, you may be able to exchange the driver's license from your home country for a valid driver's license in your host province. Some testing on Canadian traffic laws may be required.
You should check with the appropriate authority in the province you will be studying in for full details on how to obtain a valid provincial driver's license. You may also want to investigate the option of getting an International Driver's License, which is valid in different countries.
