If you lose your job (for example, you resign or are laid off) and you believe you lost your job because of your sight loss, you should get help from a lawyer to understand what your legal options are. A lawyer can help you determine whether your employer may have discriminated against you in a way that breaks the law.
If you leave your job voluntarily to receive Employment Insurance benefits, you may have to prove that you took every reasonable alternative available to you to avoid unemployment to receive benefits.
