A group registered retirement savings plan (RRSP) is a company-sponsored plan that an employer offers to all eligible employees. A group RRSP is like an individual RRSP but administered on a group basis by the employer. Contributions are made by pay-roll deduction, on a pre-tax basis, through a Group RRSP administrator. 

Although it is not required for employers to match the contributions, it could be an excellent way to really enhance the group RRSP benefits and add a lot more value to it.
