The difference experience makes
Most neutrals bring legal credentials. Chantelle brings something rarer: the perspective of someone who has sat on all sides of the table.
As advocate, executive, and adjudicator, Chantelle has sat on every side of the table. She understands what employers need, what is at stake for employees, and what a decision-maker requires to reach a defensible, principled outcome.

Understanding the options before you choose
- What is the difference between arbitration and mediation?
- In arbitration, a neutral arbitrator hears the matter and issues a final, binding decision, similar to a court judgment but private and usually faster. In mediation, a neutral mediator helps the parties negotiate their own resolution; it is facilitated and non-binding. Chantelle offers both, and can advise which fits a given dispute.
- At what stage of a dispute can Chantelle be engaged?
- At any stage. Chantelle can mediate before proceedings are filed, during litigation, or on the eve of a hearing, and she accepts arbitration and adjudication mandates as well as workplace investigation and assessment engagements.
- Who does Chantelle work with?
- She maintains a neutral practice and welcomes inquiries from counsel, employers, organizations, unions, and parties seeking an experienced, impartial dispute resolution professional. As a neutral, she does not act as an advocate for any side.
- What kinds of matters does Chantelle handle?
- Labour and commercial arbitration, mediation across labour, employment, commercial, and workplace matters, independent workplace investigations into harassment, discrimination, and misconduct, workplace assessments, and adjudication of Labour Relations Board matters. Her command spans labour, employment, and health law.
- What does an independent workplace investigation involve?
- When a complaint of harassment, discrimination, misconduct, or policy violation arises, Chantelle conducts an independent, procedurally rigorous investigation that is fair to all parties, defensible in any forum, and supported by a clear, well-organized written report.
- How is a workplace assessment different from an investigation?
- A workplace assessment is an objective, advisory read on workplace culture, dynamics, or specific concerns, without the formality of an investigative process. It helps leadership understand what is happening and take proactive steps, where a formal investigation is not needed.
