MBS Plus LLP is an accounting firm that has evolved over time. Its origins date back to 1995 when Ana Johnson acquired Milton Business Services. In 1997, the company relocated to Mississauga where it found a growing need for both bookkeeping and personal tax services. In 2002 Johnson & Robinson Professional Corporation, Chartered Accountants, was founded and became a part of the MBS umbrella.  In 2010, Numbers Plus Professional Corporation, Chartered Professional Accountant was formed by Mark Stebbing.  Ana, Harold and Mark knew of one another since 2010 and have always respected the way each other’s knowledge, business acumen and approach to serving clients.  In the fall of 2019 they decided to join forces and formed MBS Plus LLP, Chartered Professional Accountants, a professional partnership headed by Harold and Mark with Ana staying on as a key team member of the new firm.


MBS Plus LLP is the bringing together of all the facets of the former businesses under one umbrella with the purpose of streamlining and simplifying the different services offered by MBS Financial Group (MBS Business Services which was working with Johnson and Robinson Professional Corporation) and Numbers Plus Professional Corporation
