Ontario Fuel Tax Act, R.S.O. 1990, c. F.35; Regulation 464, R.R.O. 1990. Governs Ontario fuel-tax rates on clear diesel/biodiesel/kerosene (currently 9 ¢/L, permanently set effective July 1, 2025) and the coloured (dyed) fuel regime.

Coloured (Dyed) Diesel: Red dye injected at 170–190 ppm by registered dyers only. Eligible uses: non-licensed (no plate) farm equipment, unlicensed construction equipment, home heating, marine commercial (not pleasure), reefer/auxiliary equipment from a separate (non-vehicle) tank. Prohibited in any motor vehicle licensed under the Highway Traffic Act. First-offence fine for misuse: $440. Up to $1,000,000 fine and/or 2 years imprisonment for tampering. Penalty assessment can be up to 13× the tax. Records must be kept 7 years.

Section-specific penalty framework

A comprehensive review of the Fuel Tax Act (CanLII and Ontario e-Laws consolidations) identifies the offence and penalty framework as monetary and custodial only:

s. 2(7.1) — prohibition on placing unauthorized fuel in a licensed vehicle.
s. 3.9(2) — collector/distributor/registered-dyer offence (sale of fuel as coloured when not properly dyed): fine $200–$10,000 plus 3× the tax that would be payable if the fuel were clear.
s. 4.19(1) — registered dyer who refuses or neglects to colour fuel: fine $50,000–$1,000,000.
ss. 28 / 29 — assessment and objection mechanics (administrative penalties up to 13× tax for improper use or tampering, per Ministry bulletin).

Plate suspension under the Fuel Tax Act: no authority found

No section of the Fuel Tax Act authorizes suspension of a vehicle's licence plate (permit) or driver's licence as a direct penalty for repeat coloured-fuel misuse. The Ministry of Finance Investigations & Inspections Branch (Finance Inspectors are Provincial Offences Officers) lays Certificates of Offence under the Provincial Offences Act, but the Fuel Tax Act itself does not give the Minister or a court the power to suspend a plate or driver's licence.

Indirect plate-suspension pathway only

A plate or driver's licence may be suspended for unpaid Fuel Tax Act fines via the Provincial Offences Act s. 69 default-fine mechanism and Highway Traffic Act s. 46.2 plate-denial / driver-licence-suspension framework. But this is a generic default-fine pathway, not a Fuel Tax Act penalty for coloured-fuel misuse. The agriculture page should not list plate suspension as a direct Fuel Tax Act penalty.

The first-offence fine remains $440 per current Ministry of Finance guidance, sourced to the Ministry "Coloured Fuel" bulletin and the "Attention Truckers" pamphlet.

Frequently asked questions

What is Ontario's current fuel tax rate on clear diesel?

9 ¢/L, permanently set effective July 1, 2025 (previously temporary at the same rate from July 1, 2022 through June 30, 2025). The rate is set under the Fuel Tax Act, R.S.O. 1990, c. F.35, as amended by legislation introduced in the 2025 Ontario Budget. Coloured (dyed) diesel is sold at 0 ¢/L provincial fuel tax.

Can a fuel-tax conviction result in licence-plate suspension in Ontario?

A comprehensive review of the Fuel Tax Act on CanLII and Ontario e-Laws identifies no statutory authority for direct plate suspension as a fuel-tax penalty. The offence and penalty framework is monetary and custodial only: §3.9(2) fines $200–$10,000 plus 3× the tax, §4.19(1) registered-dyer offences fine $50,000–$1,000,000, §§28–29 administrative penalties up to 13× the tax. An indirect plate-suspension pathway exists only if an unpaid tax assessment becomes a judgment and is enforced under the Provincial Offences Act with consequent suspensions.

What records does the Fuel Tax Act require operators to keep?

Seven years. The recordkeeping obligation applies to anyone purchasing, selling, dyeing, transporting, or using fuel under the Act. Ministry of Finance inspectors are entitled to review those records during an audit, and missing or incomplete records are themselves an audit finding.
