What Class 53 Held
Machinery and equipment used primarily in Canada for the manufacturing or processing of goods for sale or lease — CNC machines, production lines, packaging equipment, industrial ovens — acquired after 2015 and before 2026. Through the Accelerated Investment Incentive and then the Reaccelerated Investment Incentive, most of this property qualified for a 100% first-year write-off (75% for the 2024 phase-out year).
Existing pools don't go anywhere. Machinery you acquired through 2025 keeps depreciating in Class 53 at 50% on the declining balance until the pool runs out or the equipment is sold.
The December 2025 / January 2026 Cliff
The same $100,000 machine, acquired five weeks apart:
| Acquired | Class | Year-One Claim | UCC After Year One |
|---|---|---|---|
| December 2025 | 53 | $100,000.00 | $0.00 |
| January 2026 | 43 | $45,000.00 | $55,000.00 |
The 2026 purchase still does fine — Class 43 at 30% claims 45% in year one under the RIIP — but $55,000 of deduction moves from year one into later years. As always with CCA incentives, the total deduction is identical; the timing isn't. For capital planning, the question is no longer "does it qualify?" but "when does the cash-flow benefit arrive?"
Class 53 Gotchas
- "Primarily" means more than 50% M&P use. Equipment that splits time between production and other work needs the usage case made — and documented.
- Selling into an expensed pool means recapture. Most Class 53 pools sit at or near zero UCC because of the 100% write-offs. Sell a machine for $40,000 against a zero pool and that $40,000 is income this year.
- Old registers may say Class 29. The predecessor class for 2007–2015 acquisitions. Read old schedules with the vintage in mind.
- New manufacturing buildings have their own deal. Acquired on or after November 4, 2025 and in use before 2030: 100% first-year write-off — that's a Class 1 story, separate from the machinery inside.
