The CLC does not contain as such a provision requiring that termination with notice be justified by a fair reason. However, this is implied from the division XIV of the Code on "unjust dismissal". This division provides for the right of an employee who has completed 12 consecutive months of continuous employment and is not covered by a collective agreement to make a complaint of unjust dismissal to the competent authority which may order reinstatement or compensation if the dismissal is found to be unjust. (sec. 240 and 242 CLC)
Complaint of unjust dismissal are not available to employees who have been laid off because of lack of work or because of the discontinuance of a function (sec. 242 (3.1) CLC)
Sec. 94 (3) CLC:
"Prohibitions relating to employers:

(a) refuse to employ or to continue to employ or suspend, transfer, lay off or otherwise discriminate against any person with respect to employment, pay or any other term or condition of employment or intimidate, threaten or otherwise discipline any person, because the person
(i) is or proposes to become, or seeks to induce any other person to become, a member, officer or representative of a trade union or participates in the promotion, formation or administration of a trade union,
(ii) has been expelled or suspended from membership in a trade union for a reason other than a failure to pay the periodic dues, assessments and initiation fees uniformly required to be paid by all members of the trade union as a condition of acquiring or retaining membership in the trade union,
(iii) has testified or otherwise participated or may testify or otherwise participate in a proceeding under this Part,
(iv) has made or is about to make a disclosure that the person may be required to make in a proceeding under this Part,
(v) has made an application or filed a complaint under this Part, or
