Specialty verticals and client fit
Owner-managed businesses ($500K to $50M revenue)
The firm’s core client is the Ontario owner-operator with a Canadian-Controlled Private Corporation (CCPC) generating $500,000 to $50,000,000 in revenue. Engagements typically span year-end financial statements (Notice to Reader, Review, or Audit), T2 corporate return, personal T1 for the shareholder-manager, HST filings, and integrated remuneration planning across salary, eligible dividends, non-eligible dividends, and shareholder loan repayment.
Medical practices and Medicine Professional Corporations
Physicians incorporating under Ontario Regulation 665/05 require a Medicine Professional Corporation whose share structure is constrained by the regulator. Insight handles incorporation, family-member share planning within the permitted class structure, and the annual T2 / T1 integration for physician practices billing OHIP or operating cash pay clinics.
Dental practices
Dental practice tax planning intersects with the HST rebate available where the practice supplies both zero-rated and taxable items (e.g., orthodontic appliances, cosmetic services). The firm also advises on practice purchase and sale transactions including asset vs share purchase, DPC (Dentistry Professional Corporation) structuring, and associate compensation.
Real estate investors
The firm advises real estate investors on the critical distinction between business income (fully taxable, no capital gains treatment) and capital gains treatment, HST self-assessment on new residential rentals, GST/HST New Residential Rental Property Rebate, and the Underused Housing Tax (UHT) filing obligation for non-Canadian owners and certain Canadian corporations.
Construction contractors
Construction engagements require attention to Work-in-Process (WIP) accounting, statutory holdback receivable and payable tracking under the Construction Act (Ontario), T5018 subcontractor slip preparation, and CRA payroll compliance for field labour. The firm handles both ASPE and IFRS-based percentage-of-completion recognition.
Technology startups
Startups typically need SR&ED credit consultation (federal ITC plus provincial OITC and ORDTC), stock option plan design under ITA s.7, employee vs contractor characterization for developers, and eventual QSBC purification to preserve the founder’s LCGE eligibility on exit.
Professional corporations (legal, accounting, engineering)
Regulated professionals in Ontario may incorporate their practice under governing statutes: the Law Society Act (LPC), CPA Ontario Act (CPA PC), and Professional Engineers Act (PEC). The firm handles incorporation, the annual compliance filings each regulator requires, and integration of the professional corporation into the practitioner’s overall tax plan.
Non-profit and charity boards
Ontario NPOs incorporated under the Not-for-Profit Corporations Act, 2010 (ONCA) and federally registered charities under CRA Registered Charity rules require distinct compliance streams. The firm delivers Review Engagements, Audit Engagements under CAS, and T3010 preparation for registered charities.
Condominium corporations
Ontario condominium corporations incorporated under the Condominium Act, 1998 require audited annual financial statements (subject to owner waiver in permitted cases) and coordinate with a qualified reserve fund study provider on a three-year cycle. The firm delivers the audit engagement.
Common client questions
What is an LPA and why does it matter?
A Licensed Public Accountant (LPA) is a CPA who has completed the additional practical experience and post-designation licensing requirements set by CPA Ontario under the Public Accounting Act, 2004. Only an LPA can sign an audit report or a review engagement report on the financial statements of a “reporting entity” in Ontario. If you need an audited or reviewed set of financial statements — for a bank covenant, condominium corporation, non-profit, or private-company shareholder agreement — the practitioner signing the report must hold an active Public Accounting Licence in Ontario.
What geographic areas do you serve?
The firm’s registered office is in Mississauga, Ontario. It serves clients across the Greater Toronto Area, Peel, Halton, York, Durham, and Ontario generally. For clients outside Ontario, the firm can act on federal tax matters (CRA is federal); provincial audit or review sign-off outside Ontario is coordinated with a locally licensed practitioner where required.
Do you serve corporations only, or personal returns too?
The firm serves owner-managers holistically: the T2 corporate return, the shareholder-manager’s T1 personal return, family member T1s where they receive dividends or salary, and any related trust (T3) returns. Personal-only T1 clients are accepted where they connect to an owner-manager engagement.
What is the typical engagement structure?
Most engagements start with a scoping conversation via the /start/ intake form. From there the firm proposes a written engagement letter identifying the services, the reporting standard (Notice to Reader compilation, Review under CSRE 2400, or Audit under Canadian Auditing Standards), and a fixed or fee-schedule quote. Ongoing bookkeeping is subscription-based; year-end work is quoted per engagement.
How do you handle CRA audits and reviews?
CRA correspondence audits, desk reviews, and field audits are represented on the client’s behalf. The firm responds to CRA queries, prepares the documentation package, and represents the client through Notice of Objection where warranted. For high-stakes matters the firm coordinates with tax counsel.
What is your fee structure?
Bookkeeping is quoted monthly on a subscription basis. Year-end financial statement and T2 engagements are quoted per engagement based on complexity. SR&ED and reorganization consulting engagements are quoted on a scoped-project basis. Fees are disclosed in the engagement letter before work begins.
Do you work with non-resident owners?
Yes. The firm regularly handles Part XIII non-resident withholding, Regulation 105 payments to non-residents for services rendered in Canada, Section 216 rental income elections, Section 217 elections, tax treaty relief analysis, and NR4 slip preparation. Non-resident director and shareholder scenarios for Canadian corporations are a regular part of the practice.
How quickly can you respond?
Initial intake responses through /start/ are typically returned within one business day. Ongoing client email is answered within one to two business days outside busy season and within two to three business days during the personal T1 filing window (mid-March to April 30) and the corporate June 15 self-employed T1 deadline.
What software do you use?
The firm works in QuickBooks Online and Xero for client bookkeeping, Caseware for compilation, review, and audit engagements, TaxCycle and CCH iFirm for T1 / T2 / T3 preparation, and the CRA Represent a Client portal for correspondence.
Do you offer virtual meetings?
Yes. All engagements can be delivered fully virtually via video conferencing, secure document exchange (encrypted portal), and electronic signature. In-person meetings at the Mississauga office are available on request.
