If you are a lawyer, accountant, or other licensed professional thinking about structuring your practice as a partnership, you have likely come across the term Limited Liability Partnership, or LLP. It is a popular business structure in Canada for good reason: it gives partners the operational flexibility of a traditional partnership while providing meaningful protection from the negligent acts of other partners.
That said, opening a limited liability partnership in Canada is not as simple as signing a partnership agreement and getting to work. There are specific requirements that vary by province, eligibility rules tied to your profession, registration obligations, and tax implications you need to understand before you start. This guide walks through everything step by step, in plain language.
What Is a Limited Liability Partnership in Canada?
A limited liability partnership (LLP) is a type of business structure that blends features of a general partnership with a layer of liability protection. In a standard general partnership, all the partners are personally responsible for the debts and obligations of the business, including the professional negligence of their co-partners. That means if one partner makes a serious mistake, the personal assets of every other partner can be at risk.
An LLP changes that dynamic. Under the LLP structure, partners are not personally liable for the negligent acts or misconduct of other partners. Each partner remains responsible for their own professional conduct, but they are shielded from the consequences of what another partner does wrong. This is the core protection the structure offers, and it is the main reason professional service firms favour it.
It is important to understand what an LLP is not. It is not a corporation, and it is not a sole proprietorship. Unlike a corporation, an LLP is not a fully separate legal entity for all purposes. Partners are still generally liable for the general business debts of the partnership. The protection is specifically around partners professional negligence and tortious acts, not around every obligation the firm takes on.
According to the Canada Revenue Agency, a partnership does not pay income tax on its operating results and does not file an annual income tax return. Instead, each partner reports their share of the partnership income or loss on their own personal tax returns. This flow through taxation model is one of the key advantages of LLP status over incorporating.
Who Can Form an LLP in Canada?
This is where Canada differs significantly from some other countries. In Canada, the LLP structure is not open to everyone. It is primarily restricted to regulated professionals, and the specific eligibility rules depend on the province where you want to register.
In Ontario, for example, only lawyers, paralegals, chartered professional accountants, and general accountants are currently permitted to form a limited liability partnership LLP. The Ontario government instructions for registering under the Business Names Act make this explicit: only these licensed professions may use the LLP form. That means if you are a software company or a retail business, the LLP structure is not available to you in Ontario.
In British Columbia, the rules are similar. Professionals practising law must register with both the provincial registry and the Law Society of British Columbia, and every partner in the LLP must be a member of the Law Society or a recognized legal profession in another jurisdiction.
Other provinces have their own set of rules. Alberta, Saskatchewan, and Quebec each govern LLPs through their respective Partnerships Act and professional legislation. Before you take any steps toward registering, confirm with your governing body whether your profession is authorized to form an LLP in your province.

LLP vs. Other Business Structures: How They Compare
LLP vs. General Partnership
In a general partnership, all the partners share unlimited liability for everything the business does. If a client brings a negligence claim against one partner, all the partners can be on the hook personally. A limited liability partnership removes that shared exposure for the professional negligence of other partners, which is a significant difference for anyone in a high-risk professional practice.
LLP vs. Limited Partnership
A limited partnership has two distinct classes of partners. Limited partners invest capital but do not participate in daily operations, and their liability is capped at their investment. General partners run the business and carry unlimited liability. In an LLP, there is no such division. All the partners can be involved in running the business, and all of them benefit from the same liability protection. Limited partnerships are commonly used for investment vehicles and real estate funds, not for professional service firms.
LLP vs. Corporation
A corporation is a fully separate legal entity. It files its own income tax return, pays corporate tax, and shareholders are generally protected from business debts. But that tax treatment introduces the risk of double taxation: the corporation pays tax on profits, and shareholders pay personal tax again on dividends. An LLP avoids this through flow through taxation. Profits and losses pass directly to individual partners, who report them on their personal tax returns at their personal tax rates. For many professionals, this is a simpler and more tax-efficient arrangement.
LLP vs. Sole Proprietorship
A sole proprietorship is the simplest structure, where one person runs a business and is personally responsible for all of it. There is no liability protection and no separation between personal assets and business obligations. If you are currently operating as a sole practitioner and considering taking on a partner, moving to an LLP gives you both the ability to collaborate and the protection against each other’s mistakes.
How to Open a Limited Liability Partnership in Canada: Step by Step
The following steps provide a general framework. Always confirm the specific requirements with the provincial registry and your governing body, as the registration process varies by province.
Step 1: Confirm Eligibility with Your Governing Body
Before doing anything else, check with your professional governing body to confirm that your profession is authorized to operate through an LLP in your province. For lawyers in Ontario, this means consulting the Law Society of Ontario. For accountants, it means checking with CPA Ontario or the relevant provincial body. For lawyers in British Columbia, check with the Law Society of BC.
Your governing body will also have its own set of approval requirements that sit alongside the provincial registration process. In some cases, you will need the governing body’s written authorization before you can complete your registration with the provincial registry.
Step 2: Choose and Reserve Your Business Name
Your firm name must include the words “Limited Liability Partnership” or the abbreviation “LLP” as the last words or letters. This is a legal requirement under the Business Names Act in Ontario and equivalent legislation in other provinces. The name must be distinctive and cannot be the same as or confusingly similar to an existing registered business name.
In Ontario, you can search existing registered names through the Ontario Business Registry before applying for your name reservation. In British Columbia, name reservations are handled through BC Registries and Online Services.
Step 3: Draft a Partnership Agreement
While a partnership agreement is not always legally required to form an LLP, it is strongly recommended and in practice it is essential. This document sets out the rights and responsibilities of each partner, how profits are distributed among partners, how decisions are made, what happens when new partners join, and what the process is if a partner leaves or the partnership dissolves.
Without a written partnership agreement, your LLP will be governed by the default rules in the provincial Partnerships Act, which may not reflect what the partners actually want. A well-drafted agreement protects all the partners and reduces the risk of disputes down the road. It is worth having a lawyer review or draft this document properly rather than relying on a template.
Step 4: Register Under the Business Names Act
In Ontario, you register your LLP name under the Business Names Act through the Ontario Business Registry. The registration fee is $60 when filed electronically. You will need to provide the firm name, a description of the primary business activity using the appropriate NAICS code, the address of the principal place of business, and the names of the partners or the designated partner. Registrations must be renewed every five years.
In British Columbia, the process involves filing a Form 1 Registration Statement with BC Registries. The total registration process in BC typically takes four to six weeks, including the name reservation stage which alone can take fifteen to twenty business days. Expedited processing is available for an additional fee.
Step 5: Obtain Approval from Your Professional Governing Body
Most professions require a separate approval or registration with the governing body in addition to the provincial registry filing. In BC, the Law Society must provide written authorization before the LLP can be registered with BC Registries. In Ontario, lawyers and paralegals must comply with specific by-laws of the Law Society of Ontario regarding liability insurance for each partner.
For accountants in Ontario, CPA Ontario must approve the firm before it can operate as an LLP. This step is not optional and failure to complete it can affect the validity of your LLP status.
Step 6: Obtain a Business Number from the CRA
Once your LLP is registered provincially, you can register with the Canada Revenue Agency to obtain a Business Number (BN). This number is used for all government correspondence and tax filings. If your LLP’s taxable supplies exceed $30,000 annually, you are also required to register for GST/HST.
Step 7: Open a Business Bank Account
Keep your personal bank accounts entirely separate from the LLP’s finances. Opening a dedicated business account in the LLP’s registered name is a basic but important step in maintaining the integrity of the structure and making accounting straightforward. Mixing personal and business finances creates problems both for tax purposes and for demonstrating that the LLP is operating as a legitimate separate business entity.
Step 8: Arrange Liability Insurance
Most governing bodies require LLP partners to maintain a minimum amount of liability insurance. In Ontario, lawyers and paralegals must carry professional liability insurance for each partner in accordance with the Law Society’s by-laws. Even where it is not strictly mandated, carrying adequate insurance is simply prudent practice. The liability protection an LLP offers does not replace insurance. It protects you from your partners’ negligent acts, but you remain personally liable for your own professional conduct.
Tax Treatment of an LLP in Canada
One of the most practical reasons professionals choose the LLP structure is its tax treatment. Understanding how it works helps you plan properly from the start.
Flow Through Taxation
An LLP is not a taxable entity in Canada. As confirmed by the CRA’s guidance on partnership income, the partnership itself does not file an income tax return or pay tax on its earnings. Instead, profits and losses flow through to individual partners, who each include their allocated share in their personal tax returns for the year. This is true whether or not the income was actually distributed in cash.
Personal Tax Rates Apply
Because income flows through to the partners, each partner pays tax at their own personal tax rates rather than at the corporate rate. For many professionals, this can be an advantage over the corporation structure, particularly if the income will be withdrawn from the business immediately rather than retained. However, if you intend to accumulate and reinvest profits within the business over time, a corporation may offer lower tax rates on retained income. The right choice depends on your specific situation.
Avoiding Double Taxation
One of the often-cited benefits of an LLP compared to a corporation is the avoidance of double taxation. In a corporation, profits are taxed at the corporate level and then dividends paid to shareholders are taxed again at the personal level. In an LLP, there is only one level of tax: each partner pays personal tax on their share of the partnership income. This can simplify tax planning considerably.
GST/HST Obligations
The LLP must register for GST/HST if its annual taxable supplies exceed $30,000. Once registered, the LLP collects GST/HST from clients and remits it to the CRA. Input tax credits can be claimed on eligible business expenses. This is separate from the income tax obligations of the individual partners.
T5013 Partnership Information Return
Larger partnerships may be required to file a T5013 Partnership Information Return with the CRA. This return provides information about the partnership’s income, deductions, and the allocation of income among partners. Check the CRA’s T5013 filing requirements to determine whether your LLP must file this return.
What the Liability Protection Actually Covers
It is worth being clear about what the limited liability in an LLP does and does not protect you from, because there is often confusion on this point.
The protection covers the professional negligence and tortious acts of other partners. If your co-partner makes a serious error that results in a claim against the firm, your personal assets are generally protected from that claim. You are not personally responsible for the harm caused by another partner’s actions.
The protection does not cover your own negligence. You remain personally liable for your own professional conduct. If a client suffers harm because of something you did or failed to do, the LLP structure does not shield you. This is why maintaining adequate liability insurance matters so much.
Partners also remain generally personally liable for the general business debts of the partnership that they have personally guaranteed. The LLP structure is not a substitute for sound financial management. It provides specific legal protection in a defined area: the negligent acts of your fellow partners.
Adding New Partners and Maintaining LLP Status
When new partners join the firm, they must meet the same eligibility requirements as the founding partners. In a law firm, for example, each new partner must be a member of the relevant Law Society. The partnership agreement should include clear provisions for how new partners are admitted, what their rights and obligations are, and how their initial capital contribution is handled.
You should also notify the provincial registry of any material changes to the partnership, including changes to the partners. In Ontario, these changes are recorded through the Business Names Act registration. Keeping your registration current is not optional. Failing to update the registry can create legal and administrative complications, particularly if a dispute arises.
Common Mistakes to Avoid When Setting Up an LLP
Skipping the partnership agreement. Some partners assume a verbal understanding is enough. It is not. Without a written agreement, you are relying on the default rules in the Partnerships Act, which may not reflect what you actually agreed to. Disputes over profits, decision-making authority, and what happens when a partner leaves are far more damaging and expensive to resolve without a clear written document.
Assuming all provinces have the same rules. They do not. The eligibility criteria, registration process, fees, timeline, and insurance requirements all vary by province. What applies in Ontario does not automatically apply in Alberta or British Columbia. Always check the specific requirements for the province where your firm will be registered.
Failing to maintain minimum insurance. Many professionals register the LLP and then neglect the insurance requirements of their governing body. This can put your LLP status at risk and potentially expose you to personal liability in situations where you expected to be protected.
Commingling personal and business finances. Keeping personal bank accounts separate from the LLP’s accounts is both a legal best practice and a practical necessity for clean accounting and tax filing.
Not seeking professional advice before registering. The requirements are technical, and the consequences of getting them wrong range from registration delays to invalid LLP status. Before you complete any filings, consult a lawyer who understands professional corporation and partnership law in your province.
Final Thoughts
Opening a limited liability partnership in Canada is a sensible choice for many regulated professionals. The structure offers real liability protection against the negligent acts of other partners, a straightforward flow through taxation model that avoids double taxation, and the flexibility to structure operations without the formality of a corporation.
The process requires careful attention to provincial requirements, professional governing body approvals, registration under the Business Names Act, a properly drafted partnership agreement, and ongoing compliance with insurance and renewal obligations. None of these steps are particularly difficult, but skipping any of them creates problems.
