If you are eligible to make a CICA claim and another claim alongside it (such as an assault at work claim against your employer), it is possible to make both.
However, you will not be compensated twice for the same harm. In other words, you will be compensated for your injuries but each claim will take into account what you have received under the other.
For example, if you recover injury compensation from the CICA, and later receive compensation from your employer, you will have to repay the appropriate amount to the CICA from the later compensation.
Likewise, if you received criminal injury compensation from your employer first, the CICA may withhold or reduce any compensation they award – so that you are only compensated for your injuries once.
