About Andriessen & Associates

Andriessen & Associates is a Toronto business law firm that's worked for companies in the courtroom and the boardroom for more than 30 years. It acts for businesses of every size, from sole proprietorships up to multinational corporations, and handles everything from drafting a company's documents to taking its disputes all the way to court.

Managing lawyer Inga B. Andriessen founded the firm in 1993 and has practised nothing but business law since. Inga also holds the role of Drafting Subject Matter Expert with the Law Practice Program and hosts @IngaTalk, an occasional podcast.

Two associate lawyers round out the legal team. Robin K. Mann earned a law degree at the University of Ottawa and moved over from family law practice in June 2018. Ariel Dorfman, who pairs an Osgoode J.D. with an undergraduate degree in finance, came on board in January 2024 after articling in personal injury law. Licensed paralegal Murray Brown and a group of law clerks, among them an ILCO certified clerk and a clerk dedicated to Small Claims files, support the lawyers.

Most non-litigation business work here is billed at a flat rate, which lets owners plan their legal budget and raise every question they've got without an hourly meter running. Small Claims Court files are flat-fee too, and the office is at 703 Evans Avenue, Suite 101, in Toronto.

History

The firm's start was anything but routine. In 1993 Inga B. Andriessen, newly called to the bar with an Osgoode Hall Law School degree, went into an interview for a law job and left with an invitation to open a law firm instead. Inga took it. By 2002 the practice was based in Suite 900 at 701 Evans Ave., and by 2003 it was operating as Andriessen & Associates, Professional Corporation, a firm whose lawyers were all corporate and commercial trial lawyers.

Practice areas

Company formation and ongoing corporate work

The firm helps owners decide which kind of business organization fits, and once a company is incorporated it prepares the bylaws, registers the Articles and walks owners through how shareholders are organized. Long-term clients count on it for the government filings that keep a corporation in good standing, and it also acts on business sales, mergers and acquisitions, with advice in plain English on daily operations, growth and dealings with suppliers and customers.

Employment law for employers only

Andriessen & Associates represents employers and no one else. It shapes HR policies around legislation and case law, advises on harassment and violence rules and Human Rights obligations, and defends wrongful dismissal suits and Human Rights Tribunal applications. An employee handbook is a flat $2,250, and a first employment agreement is $1,000, with $250 for each sub-agreement. (Fees as of October 2026.)

Collections and Small Claims Court

The firm collects debts of any size, starting with a demand letter to nudge a slow payer when that's all it takes. Small Claims Court cases are handled up to Ontario's $50,000 limit on a flat fee set in line with what a successful judgment will include, and larger debts are pursued at the firm's regular hourly rates. (Fees as of October 2026.)

Commercial and equipment leasing

Andriessen & Associates drafts and enforces commercial leases for landlords and for tenants, negotiates lease terms and reviews offers to lease, often at a flat rate; for residential tenancies it acts only for landlords. Its lease suits often involve removing a tenant, going after one who left before the term ended, dealing with goods left behind, or tracking down a tenant who reopened under a new name. Equipment lessors in fields like office equipment and motor vehicles get over 25 years of lease drafting and litigation experience, whether they need equipment repossessed or a deficiency claim pursued too.

Business litigation

The firm litigates in every area of business law, including enforcing judgments from outside Ontario within the province. Inga B. Andriessen's own practice is about 70% litigation, and Ariel Dorfman works in business litigation.

Wills, trusts and probate

Wills and estate planning for most people are done at a flat rate, while complex estate planning questions are billed hourly. The team also sets up trusts, handles probate, and helps with estate disputes and any litigation that follows.

How Andriessen & Associates works

In lawsuits, the goal at Andriessen & Associates is real money for the client rather than a judgment that only exists on paper, and the firm commits to moving cases along as quickly and cost-effectively as it can. During litigation its lawyers advise clients on putting an offer to settle forward to help secure a better costs award at trial, and they bring in team members with lower hourly rates to keep costs down. The firm also uses a legal-specific AI tool for tasks like building timelines and reviewing documents.
