There is an X in the CPP/QPP in box 28 of my T4, does this mean I am exempt? It says it is rare so I'm not sure.

Box 28 on your T4 slip specifies CPP/QPP, EI, and PPIP exemptions. This means that your employer did not withhold (or deduct) CPP/QPP contributions, EI premiums, and/or PPIP premiums from your pay.
