Separating in Ontario involves two sets of rules. The federal Divorce Act governs the divorce itself, along with parenting and support, while Ontario’s Family Law Act decides how property is shared through the equalization of net family property. This guide profiles 10 divorce and family lawyers serving Markham, Unionville, Richmond Hill, Thornhill, and the rest of York Region. Each firm was evaluated on how much of its practice is devoted to family law, its experience with equalization, support, and parenting disputes, whether it offers mediation or collaborative practice, and how often its lawyers appear in the Ontario Superior Court of Justice in Newmarket.
When comparing options, ask three practical questions. First, does the lawyer practise family law exclusively, or is it one of many practice areas? Second, is the firm better suited to negotiated settlements, collaborative practice, or contested litigation, and which does your situation need? Third, how is billing handled, and are unbundled or fixed-fee services available? This is not a ranked or sponsored list. Firm details were drawn from each firm’s own website, legal directories such as Best Lawyers, Martindale-Hubbell, Lawyerinfo.ca, and Three Best Rated, and public business listings.

Frequently Asked Questions
How long do I have to be separated before getting a divorce in Ontario?
Under section 8 of the Divorce Act, the most common ground for divorce is a breakdown of the marriage shown by the spouses living separate and apart for at least one year. Divorces can also be granted on the grounds of adultery or cruelty, but these are rarely used. You do not have to wait a year to resolve parenting, support, and property issues; those can be addressed in a separation agreement or court order right away.
How is property divided in an Ontario divorce?
Ontario does not divide every asset in half. Instead, under section 5 of the Family Law Act, each spouse calculates their “net family property,” the increase in their net worth during the marriage, and the spouse with the higher amount generally pays the other half the difference, known as an equalization payment. The matrimonial home receives special treatment even if one spouse owned it before the marriage.
Is there a deadline to claim an equalization payment?
Yes. Under section 7(3) of the Family Law Act, an application for equalization must generally be brought within the earliest of two years after a divorce is granted or six years after the date of separation. Missing these deadlines can mean losing the claim entirely, which is why lawyers such as the team at Feldstein Family Law Group recommend getting advice early.
How is child support calculated in Ontario?
Child support is calculated using the Federal Child Support Guidelines for divorcing parents, which set a base amount based on the paying parent’s income and the number of children. Parents may also share special or extraordinary expenses such as childcare, medical costs, and post-secondary education in proportion to their incomes. Spousal support is calculated differently, often with reference to the Spousal Support Advisory Guidelines.
Where are Markham divorces heard?
Family cases for Markham residents are heard at the Ontario Superior Court of Justice in Newmarket, which serves York Region. Before a case conference in most contested family cases, both parties must attend a Mandatory Information Program session that explains the court process and alternatives such as mediation.
How much does a divorce lawyer cost in Markham?
Most Markham family lawyers bill hourly and require a retainer, with costs depending on how contested the case is and whether property or parenting issues are complex. Uncontested divorces and negotiated separation agreements can cost far less than litigation. Some firms offer unbundled services, where you pay for help with only part of the case, or collaborative practice, which can reduce costs by keeping the matter out of court. Ask each firm for a written estimate and a clear explanation of its billing practices.
