Why Oshawa Corporations Choose Gondaliya CPA for Corporate Tax Filing
Oshawa is the economic hub of Durham Region with over 175,000 residents and more than 8,000 registered businesses spanning automotive manufacturing, advanced manufacturing, healthcare, technology, construction and professional services. The GM Oshawa Assembly Complex anchors a supply chain of hundreds of auto parts manufacturers, tool and die shops, logistics companies and engineering firms that invest heavily in production equipment requiring correct CCA classification.
These businesses need CCA Class 43 (30% for manufacturing equipment), Class 53 (50% for qualifying M&P machinery), Class 12 (100% for tooling, dies and moulds) and the Clean Technology Investment Tax Credit of up to 30% on qualifying EV manufacturing equipment. Incorrect CCA class assignment costs Oshawa manufacturers thousands in under-claimed deductions annually. We file every T2 with the documentation that prevents Durham Region TSO reviews from escalating. Flat-fee from $400. Oshawa CPA Services.

Case Studies: Corporate Tax Filing in Oshawa
Auto Parts Manufacturer, GM Corridor (CCA Reclassification)
An Oshawa auto parts manufacturer supplying the GM assembly plant had classified all CNC machining centres, robotic welding cells and stamping presses under CCA Class 8 (20%) for three years. Our review reclassified $520,000 in qualifying equipment to Class 53 (50% M&P) and identified $180,000 in EV-related tooling eligible for the Clean Technology ITC at 30%. We filed T2 amendments for two prior years. Oshawa CPA Services →
General Contractor, Durham Region (T5018 Penalty Prevention)
A Whitby-based general contractor operating across Oshawa and Durham Region had never filed T5018 subcontractor payment statements despite paying over $450,000 annually to sub-trades. CRA had also flagged three workers classified as contractors who appeared to be employees. We prepared two years of T5018 statements, filed a voluntary disclosure and reclassified the three workers with minimum assessment.
Medical Corp, Lakeridge Health Area (Holdco Restructure)
A physician operating near Lakeridge Health had accumulated $380,000 in retained earnings inside the professional corporation with no holdco structure. CRA was reviewing a $72,000 management fee paid to a family-owned corporation with no written services agreement. We established the holdco, prepared retroactive management services agreements, documented fair market value and resolved the CRA review. Corporate Tax Filing →
Tech Startup, Ontario Tech Corridor (SR&ED Recovery)
An Ontario Tech University spinoff developing clean energy monitoring software had filed three years of T2 returns without claiming SR&ED. The company assumed SR&ED was only for lab research. We identified qualifying development activities including custom software architecture, AI model training and field testing protocols. Filed SR&ED claims for all three prior years. Total eligible expenditures: $340,000.
