6 worked Port Colborne case studies — the position a client typically comes to us with, what we do, and what it is worth. Each is an illustrative example built on the rules that apply to Port Colborne and its provincial tax regime, not a specific client's file.
Case Study 1 · Sale and succession
Share Sale Restructured, $270,000 Less Tax On Closing — Two-Dentist Practice, Port Colborne
Client: A two-dentist practice · Where: Port Colborne, Ontario · Engagement: 3 weeks, fixed fee
Tax saved on closing$270,000
PriceAs agreed
Post-closing adjustmentsNone
The situation — A two-dentist practice, Port Colborne, Ontario
A two-dentist practice in Port Colborne, Ontario was preparing to sell. Due diligence surfaced a shareholder loan balance that would have been picked up as income on closing. That would have reduced the price or killed the deal outright.
What we did for A two-dentist practice, Port Colborne, Ontario
We cleaned up the historical file. We rebuilt the sales ledger by customer location, applied the correct place-of-supply rate to each stream, and filed the adjusted HST returns. Then we prepared the due-diligence package the buyer's advisers actually asked for.
The result — A two-dentist practice, Port Colborne, Ontario
The deal closed at the agreed price. $270,000 of tax was saved against the structure originally proposed, with no post-closing adjustment.
Case Study 2 · Structure rebuilt
Reorganisation Completed Tax-Deferred, $72,000 Saved Each Year — Recruitment Firm, Port Colborne
Client: A recruitment firm · Where: Port Colborne, Ontario · Engagement: 5 weeks, fixed fee
Annual saving$72,000
Tax on reorganisationDeferred
Elections filedOn time
The situation — A recruitment firm, Port Colborne, Ontario
A recruitment firm in Port Colborne, Ontario had outgrown the structure it started with. A provincial payroll levy that had never been registered for or remitted was the immediate problem. The longer-term one was that the structure blocked the next step.
What we did for A recruitment firm, Port Colborne, Ontario
We mapped the current structure and modelled the target. Then we assessed and claimed Ontario Innovation Tax Credit alongside the federal return. The tax-deferred elections were filed on time and the supporting valuations documented.
The result — A recruitment firm, Port Colborne, Ontario
The reorganisation completed without triggering tax, and the new structure saves approximately $72,000 a year while removing the exposure the old one carried.

Filed with15 days to spare
Next yearPapers ready
The situation — A family medicine clinic, Port Colborne, Ontario
A family medicine clinic in Port Colborne, Ontario was weeks away from the deadline for its ON tax and accounting file. Behind that sat 13% HST charged on every sale regardless of where the customer was located. The exposure if the date slipped was around $127,000.
What we did for A family medicine clinic, Port Colborne, Ontario
We recalculated the corporate tax at the 12.2% combined small business rate and rebased the instalments on the current year. The filing went in complete rather than provisional, so there was no amended return to follow.
The result — A family medicine clinic, Port Colborne, Ontario
Filed with 15 days to spare. $127,000 in late-filing penalties avoided, and the working papers are ready for the following year.

Late remittances sinceZero
ScheduleAutomated
The situation — A translation services company, Port Colborne, Ontario
Remittances at a translation services company in Port Colborne, Ontario were consistently late by a few days. That was enough to trigger penalties every quarter. Behind it sat sector-specific exposure the previous accountant had not seen before.
What we did for A translation services company, Port Colborne, Ontario
We assessed and claimed Ontario Made Manufacturing Investment Tax Credit alongside the federal return. Then we moved the remittance dates into a scheduled process rather than a monthly decision.
The result — A translation services company, Port Colborne, Ontario
Penalties stopped from the following remittance onwards, and $114,000 of overpaid instalments was refunded.
Case Study 5 · Scaling without breaking

Cash freed$29,500
Compliance failuresNone
ReportingMonthly
The situation — A physiotherapy group, Port Colborne, Ontario
A physiotherapy group in Port Colborne, Ontario was opening in a second province. That meant different filing obligations and a different payroll regime. Out-of-province sales billed at the ON rate instead of the customer’s already sat in the file.
What we did for A physiotherapy group, Port Colborne, Ontario
We registered the provincial payroll account, caught up the outstanding remittances, and applied for relief on the penalty. We then put monthly reporting in place. That let the owner see the cash effect of growth while there was still time to act on it.
The result — A physiotherapy group, Port Colborne, Ontario
Growth was absorbed without a compliance failure. $29,500 of cash was released, and the monthly reporting now flags a problem while it is still small.
Case Study 6 · Missed incentive claimed
Incentive Review Recovered $78,000 Across 4 Open Years — Surveying Practice, Port Colborne
Client: A surveying practice · Where: Port Colborne, Ontario · Engagement: 9 weeks, fixed fee
Recovered$78,000
Open years claimed4
Ongoing trackingIn place
The situation — A surveying practice, Port Colborne, Ontario
An incentive review at a surveying practice in Port Colborne, Ontario started from a simple question: what has never been claimed? The answer ran to 4 years. It was driven by Ontario incentives claimed by competitors and never by this business.
What we did for A surveying practice, Port Colborne, Ontario
We rebuilt the sales ledger by customer location, applied the correct place-of-supply rate to each stream, and filed the adjusted HST returns. We documented eligibility to the standard a reviewer would apply rather than the standard a claim form requires.
The result — A surveying practice, Port Colborne, Ontario
The credits produced $78,000 across the open years. The tracking now in place means the following year's claim is documented as the work happens rather than reconstructed afterwards.
