The process of registering a consulting firm in Quebec involves several steps across multiple jurisdictions and agencies: registration with the Registraire des entreprises du Québec (REQ), which assigns your NEQ; registration for the GST/HST and the QST with Revenu Québec; and a federal Business Number from the Canada Revenue Agency. We'll walk you through each step.

Step 1: Understand the Legal Structure You're Registering

Before you register anything, clarify your legal structure. Are you operating as a sole proprietor, a partnership, or a corporation? The registration process differs for each.

Most independent consultants start as sole proprietors—the simplest structure, with minimal registration overhead and straightforward tax filings. If you're launching a multi-person consulting firm, you might form a corporation or partnership. The advice below covers all three, with notation where processes diverge.

For a sole proprietor or partnership operating under a business name, you'll register with the REQ. For a corporation, the registration structure is slightly different—you incorporate with provincial authorities, then register the corporation with the REQ.

Step 2: Choose Your Virtual Office Address (179 Promenade du Portage)

Select your virtual office provider and confirm your business address. At Capital Corridor Campus, the Corridor Address package ($99/month) includes a professional business address at 179 Promenade du Portage, professional mail handling, and inclusion in the building directory.

When government agencies correspond with you, mail is forwarded to the email address you've designated with Capital Corridor Campus. When you need to conduct business meetings or consultations, you can access professional meeting infrastructure on-site.

Step 3: Register with the Registraire des Entreprises du Québec (REQ)

The REQ maintains the province's business registry. You must register your business name here if you're operating under a name other than your personal name (for sole proprietors) or the legal corporation name.

For sole proprietors and partnerships, registration with the REQ is done online. A fee applies to the registration declaration. Source: Québec.ca, Registraire des entreprises fees. You'll need:

The Registraire des entreprises assigns your Québec enterprise number (NEQ). This is your unique provincial business identifier, separate from your federal business number.

Incorporating a business is a different process. For advice on your situation, speak to a lawyer.

Step 4: Register with Revenu Québec (GST/HST and QST)

In Quebec, businesses register for both the GST/HST and the QST with Revenu Québec. Source: Revenu Québec, How to register. The QST is a separate provincial tax. You must register once your taxable supplies exceed $30,000 over four consecutive calendar quarters or in a single calendar quarter. Source: Revenu Québec, Small suppliers

Revenu Québec will issue your GST and QST registration numbers. These identify you for sales tax purposes.

Step 5: Register with the Canada Revenue Agency (Federal Business Number)

Even if your consulting practice is operated from Quebec, you need a federal Business Number (BN) from the Canada Revenue Agency. This is your federal identifier, used for income tax and payroll accounts (if you eventually hire employees).

You can register online through CRA's My Business Account portal, or you can request a Business Number Registration form (RC1) from CRA and submit it by mail. When you register, you'll provide:

CRA will assign you a Business Number. In Quebec, your GST/HST registration is handled by Revenu Québec, as described in Step 4.

What Your Government Registration Looks Like

After completing the five steps above, your consulting business is registered with three agencies. Here's what you have:

If your business address is at Capital Corridor Campus, we handle mail receipt and forward correspondence to your designated email address.

Virtual Office Address in Practice: What Happens With Government Correspondence?

Here's how the virtual office mechanism works operationally. When CRA mails a notice to your business, it arrives at 179 Promenade du Portage. The Capital Corridor Campus mail team receives it, scans it, and forwards it to your email address.

The same process applies to Revenu Québec assessments, REQ notices, or any other government correspondence.

This works equally well for client correspondence. When a government client sends a formal contract to your business address, it arrives at 179 Promenade du Portage, is forwarded to you immediately. You execute the contract and return it. The transaction is seamless.

Government correspondence to your virtual office address arrives, is scanned, and is forwarded to your email.

Invoicing and Client Billing With a Virtual Office Address

When you invoice government clients, your invoice letterhead should display your registered business address. This is where it's particularly important that your address is professional and credible. An invoice with 179 Promenade du Portage as the return address signals institutional legitimacy. A home office address signals the opposite.

Your invoice should include: your business name, your business address, your GST and QST registration numbers, and your contact email and phone.

The virtual office address lends credibility to every invoice you send. It positions you as a professional, established firm—which you are.

Insurance

For advice on professional liability insurance, speak to a licensed insurance broker. For tax or legal advice on your situation, speak to an accountant or a lawyer.

Scaling Beyond the Virtual Office Address

As your consulting practice grows and you generate revenue, you might scale from the Corridor Address tier ($99/month) to the Corridor Office tier ($199/month), which includes dedicated desk access, phone support, and meeting room capability. Later, you might move to Corridor Executive ($349/month) for full office access.

Your business address remains 179 Promenade du Portage throughout all these tiers. You're not changing your business registration or your government registration. You're simply upgrading the operational infrastructure you're using. Your NEQ, tax registration numbers and Business Number stay the same.

Only when your practice generates enough revenue to justify a traditional commercial lease would you consider moving to dedicated space. By that point, you'll have established your business, proven your revenue model, and can negotiate lease terms from a position of strength.

Cost Summary

Here are the costs to plan for:

The Bottom Line

Starting a consulting firm in Quebec means registering with three agencies: the REQ, Revenu Québec and the CRA. Government correspondence is handled efficiently. Invoicing to clients is professional and credible.

The virtual office model gives you a business address at 179 Promenade du Portage—a LEED Gold building—at $99 per month. You're not paying for office space you don't need. You're paying for the institutional credibility and government client confidence that a prestigious address provides.

If you're launching a government-adjacent consulting practice, the registered address is your first investment. Make it count.
