How we ranked Oshawa mediators

A law firm with no Google reviews scores zero on rating, review volume and recency. Other unknown factors are left out, not counted as zero. Scores last refreshed November 9, 2026.

Paid placement never changes a rank or score. Attorney advertising businesses are paid, labelled, limited to 3 and shown above the ranking, outside it.

How to choose a mediator

  1. Check the lawyer’s status and any public discipline in the state bar or law society directory.
  2. Ask how many mediation matters the lawyer handles each year, and who at the firm will do the work.
  3. Get the fee arrangement in writing: hourly, flat or contingency, and which costs are charged on top.
  4. Ask how and how often the firm will update you, and how fast it answers calls and emails.
  5. Read recent reviews for how the firm communicated and billed, not only for outcomes.
  6. Ask whether the mediator is a lawyer, what mediation training or accreditation they hold, and how many matters like yours they have mediated.
  7. Meet more than one firm; many offer a short first consultation, sometimes free.

Questions to ask a mediator

  • How would you approach a matter like mine, and what are the realistic options?
  • How do you charge, and what will the total likely cost?
  • Who will be my main contact, and how quickly do you reply?
  • Are you a lawyer, and who prepares the written agreement?
  • How many sessions does a matter like ours usually take?
  • Is there any conflict of interest that would stop you representing me?

Terms explained

Contingency fee
A fee that is a share of the money recovered, paid only if there is a recovery. Common in injury cases; not allowed for criminal defense or for securing a divorce.

Flat fee
One set price for a defined piece of work, such as a will or an uncontested matter.
Limited-scope representation
Paying a lawyer for part of a matter only, such as reviewing documents or coaching for one hearing (also called unbundled services).

The deadline to file a lawsuit or charge. It differs by state or province and by type of claim.
Good standing
A lawyer’s status as active and eligible to practise with a state bar or law society.
Law society
The body that licenses and disciplines lawyers in a Canadian province or territory.
Board certification
Recognition in a field of law by a state program or an organisation accredited for that purpose. Lawyers may only claim it when they hold it, naming the certifying body.
Attorney–client privilege
The rule that keeps confidential communications between a client and lawyer, made for legal advice, out of court.
Conflict check
The search a firm runs before taking a matter to make sure it does not represent someone on the other side.
Pro bono
Legal work done for free, usually for people who cannot afford a lawyer.

Yes, if they are within 64 km of the Oshawa city centre, our service radius for mediators. Each listing shows where the law firm is based and how far away it is. Proximity is 5% of the LFR Score, so a nearby law firm gets a small edge.

Mediators usually charge by the hour or a flat fee per session, and the cost is often split between the two sides. Ask for the fee arrangement in writing before you agree.

Is an agreement reached in mediation legally binding?

Mediation is voluntary and the mediator does not decide anything. If both sides agree, the terms are usually written up and signed, and in a divorce or custody matter filed with the court to become binding. Each side can have its own lawyer review the agreement first. This is general information, not legal advice.

How is this list of mediators in Oshawa, ON ranked?

By LFR Score only, from public data on reviews, practice focus, office location and hours. Firms labelled “Attorney advertising” paid for that placement; payment never changes a rank, and a rank is not an endorsement.

Does a lawyer need an office in Oshawa?

No, but the lawyer must be licensed in your province (or, for federal matters such as immigration, in some province). A local office makes meetings and court appearances easier, so proximity is one of our factors.
