Yes, you can if your spouse helps you in the business or helps you manage the office and administration, etc. for your business. You can pay a reasonable amount from the business. You can pay that either as a part-time or full-time employee or as a self-employed contractor. If you are paying as an employee then you do not need to deduct EI as your spouse will not be able to claim employment insurance. The income your spouse receives, he/she needs to report on his/her annual income tax return.
