Yes!
You are required to prove your identity AND physical address. There are many types of identification that can be accepted at the polling stations from your Saskatchewan Driver’s License to your Health Card and a utility bill.
Be sure to double check what kinds of IDs are accepted before you vote!
If you do not have sufficient ID (make sure to check the above list first as there are many acceptable ID options), you can have a registered voter in your constituency vouch for you. If this is the case, you will have to swear an oath, and the person vouching for you must be an eligible voter who has valid authorized identification. This person can only vouch for one person.
If you are voting by mail, the address on your ID must match the address you have listed on the application as your ordinary residential address.
