Requirements Overview

The most critical requirement for operating an investment banking and securities intermediation business in Mississauga is Investment Adviser Registration. This registration is legally required and you cannot operate or offer investment advice to clients without it. In addition, you will typically need Securities Dealer Registration and ongoing membership with IIROC or MFDA, along with corresponding disclosure and governance controls. This foundational licensing is non-negotiable and must be in place before you start client-facing activities.

Mandatory Operational Requirements: You must keep your people and processes safe and compliant. This means complying with the Occupational Health and Safety Act, establishing safety policies and training, and maintaining WSIB coverage for employees. You also need to meet Employment Standards Compliance for your staff, and obtain appropriate insurance such as Errors and Omissions Insurance (Securities) to protect against professional liability. On the compliance side, put in place robust Anti-Money Laundering (Securities) procedures and be prepared to meet Prospectus and Disclosure Requirements if you issue or handle securities.

Business Registration & Tax: Set up the business properly with the right numbers and registrations. Obtain a Business Number (BN) from the Canada Revenue Agency, secure any required Business Licence, and complete Ontario Business Name Registration with ServiceOntario if you operate under a name other than your legal corporate name. Don’t forget GST/HST Registration for applicable sales, and Payroll Deductions Registration if you have employees. These steps ensure you can operate legally and meet tax obligations from day one.

Encouragement: Next steps are to consult a regulatory professional to confirm the exact OSC/IIROC/MFDA requirements for your exact activities, begin the applications, and prepare your compliance program. Gather corporate documents, outline your operations plan, and build a realist
