Accountant for London, Ontario manufacturers
London’s 401 industrial parks, plus Woodstock and St. Thomas, hold auto parts suppliers, metal shops and food processors whose numbers live in inventory, work in progress and machines. EverStone serves manufacturers across London and Middlesex County remotely, at fixed fees.
Quick answer: A London, Ontario manufacturer’s taxable income turns on four things a service business never meets. The first two are how inventory and work in progress are valued at year-end, and how machinery is written off through capital cost allowance. The others are whether process work qualifies for SR&ED, and a payroll large enough to bring in Employer Health Tax. EverStone handles all four with the T2, at a fixed fee. Published fees start at $325 a month for bookkeeping and $125 for a personal return.
For a one-owner London Ontario manufacturer, monthly bookkeeping, payroll and the year-end T2 with statements usually cost from $500 to $700 a month all-in.

Inventory and work in progress move taxable income
Cost of goods sold is opening inventory plus purchases, less closing inventory. Every dollar added to the closing figure is a dollar of profit, and every dollar missed is a dollar of expense claimed too early. For a parts shop that means coil and bar stock, parts partway through the line and finished goods waiting on a release. For a food processor it means ingredients, packaging and product in the cooler.
Each is valued at the lower of cost and fair market value, on a basis that stays the same from year to year. The count at year-end is the evidence the CRA will ask for, so it is planned, done on the day, and kept. The year-end inventory count explains what has to be recorded.
Job costing that shows which parts make money
Auto-sector suppliers often run long programs where the price must hold or fall, so real cost per part is the only defence: actual material cost, direct labour hours, a burden rate covering building, power and supervision, and tracked scrap. Food processors do the same through yield and batch costs. Books split that way answer every quote: can we make this part at this price? Pricing review goes further.
Machinery, CCA and the replacement decision
Presses, CNC machines, robots and packaging lines are written off through capital cost allowance, with manufacturing and processing machinery in its own class. A machine has to be available for use before any claim starts, so equipment delivered in the last week of the year but not yet commissioned may not produce the deduction you expected. When an old machine is sold or traded, the proceeds reduce the class, and if they exceed what is left the difference comes back as recapture.
Leasing and buying produce different deductions for the same machine, and the reduced first-year claim is explained in the half-year rule. All of this is worth a conversation before the purchase order is signed. CCA classes sets out the structure.
SR&ED on process improvement
Much plant development happens on the floor: a fixture redesigned for tolerance, a failing weld process, a shelf-life line change. Systematic trials to resolve a real technical uncertainty may qualify for scientific research and experimental development credits.
The claim is made on Form T661 with the corporate return, and a Canadian-controlled private corporation can earn an enhanced refundable credit, which means cash even in a year without tax to pay. Routine production, quality control and ordinary troubleshooting do not qualify. Notes and test results made at the time are what carry a claim through review. See the SR&ED expenditure limit update.
Payroll, Employer Health Tax and the second shift
Adding a shift is often what pushes a London manufacturer past the Employer Health Tax exemption. The rate is then picked from a graduated table using total Ontario payroll before the exemption, and related companies share a single exemption between them. WSIB premiums depend on the rate group attached to the account, which is worth confirming for a shop that has changed what it makes. Shift premiums, overtime and taxable benefits all have to reach the T4. Payroll in London covers the detail.
HST on inputs, and on what crosses the border
The 13% HST paid on steel, tooling, power and freight comes back as input tax credits, so a manufacturer’s HST is mostly about capturing every credit. Goods exported to customers in Michigan or elsewhere in the United States are generally zero-rated, which can put a shop in a refund position each period. US dollar receivables and bank accounts need a consistent conversion method so exchange gains and losses land in the right year. HST on exports covers the conditions.
