Agricultural Drones and Crop Spraying in Canada: 2026 Rules

Agricultural drones are legal in Canada, but spraying a field involves two separate sets of federal rules plus your province. Transport Canada regulates the flight: registration, pilot certificate and operating category, which for most loaded spray drones means the medium-drone rules (over 25 kg up to 150 kg) that took effect on November 4, 2025. Health Canada regulates the pesticide: since June 30, 2026, products already registered for conventional aerial application can be applied by drone, provided you follow the aerial label directions and the conditions of the new policy.

On top of that, provinces and territories set their own applicator licences and permits. This guide explains how the pieces fit together for spraying, mapping and scouting, and what to sort out before your first job.

Weight classes: which rules apply to your farm drone

Transport Canada sorts drones by weight, and spray drones change class as their tanks fill. The operating weight includes the drone, batteries and payload, so a spray drone that is light when empty can be well over 25 kg on take-off.

Weight	Typical farm use	Main requirements
Under 250 g	Quick visual checks	No registration or certificate; microdrone rules apply
250 g to 25 kg (small)	Mapping, multispectral scouting, small spray units	Registration, Basic or Advanced certificate depending on the operation
Over 25 kg to 150 kg (medium)	Most loaded spray and spreading drones	Registration, Advanced certificate, drone declared for the operation, visual line of sight (or Level 1 Complex for BVLOS)
Over 150 kg	Large unmanned aircraft	Special Flight Operations Certificate

Transport Canada’s 2025 summary of changes confirms the new medium-drone category and the fees that came with the update. For general background on the 2026 framework, see our overview of Canada drone rules for 2026.

Medium-drone rules for spray operations

Any medium-drone flight is at least an advanced operation. According to the Transport Canada advanced operations page, medium drones must stay in visual line of sight and the distance from uninvolved people decides which declaration the drone needs:

• More than 152.4 m from uninvolved people: the drone needs a manufacturer safety assurance declaration for that operation.
• Between 30 m and 152.4 m: a pre-validated declaration is required.
• Within 30 m (over people): a pre-validated declaration is also required.
• Controlled airspace: air traffic control permission (in civil airspace, a NAV CANADA authorization) plus a declaration.

In practice, most field spraying happens in rural uncontrolled airspace and well away from the public, but watch for neighbours’ yards, roads and farmhands who are not part of your crew. Before you buy, ask the dealer whether the exact model and configuration has a Canadian declaration for medium-drone operations, and read our guide to safety assurance declarations. The pilot needs an Advanced certificate and the drone must be registered.

Large fields tempt operators to fly beyond sight. That now has a path without a Special Flight Operations Certificate in lower-risk areas, but only through the new Level 1 Complex category, which requires a separate pilot certificate and an RPAS Operator Certificate. See our guides on Level 1 Complex / BVLOS and the RPAS Operator Certificate.

When you still need an SFOC

Before November 4, 2025, the Canadian Aviation Regulations banned flying with explosive, corrosive, flammable or bio-hazardous payloads unless you held a Special Flight Operations Certificate, which is one reason many spray operators needed one. That paragraph of section 901.43 was repealed in the 2025 amendments. The section still prohibits payloads that could create a hazard to aviation safety or injure people, and slung loads outside the operating manuals, unless an SFOC covers them.

You should still expect to need an SFOC for operations that fall outside the standard categories, for example drones over 150 kg, flights above the normal altitude limit, or multi-drone (swarming) operations that Transport Canada has not otherwise permitted. SFOC applications now carry fees. Our SFOC guide explains the process. Because these rules are new, confirm your specific setup with Transport Canada before the season starts.

Health Canada rules for spraying pesticides by drone

Pesticides fall under the federal Pest Control Products Act, administered by Health Canada’s Pest Management Regulatory Agency (PMRA). Until mid-2026, a product could be applied by drone only if its label specifically mentioned remotely piloted aircraft systems (RPAS), and very few did. Following a consultation that opened in February 2026, Health Canada announced on June 30, 2026 a policy allowing drones to apply products already approved for conventional aerial application.

The key conditions reported for the policy are:

• Follow the aerial directions on the label, including application rate, minimum spray volume, droplet size, number of applications and re-treatment intervals.
• Do not apply by drone a product whose label says not to apply by air, or one that is not registered for aerial use (that would need an approved label amendment).
• Aerial buffer zones still apply until drone-specific buffer zones are developed.
• Separate roles: the person mixing and loading should not be the drone pilot, and the mixer/loader wears the PPE on the label.
• Crew safety: pilots, visual observers and handlers follow ground-application safety measures and stay out of the downwind path; visual observers need at least a Basic drone pilot certificate.

Read the full policy and the current label before every product you use. Using a pesticide contrary to its label is an offence, and labels can be amended to restrict drone use.

Provincial pesticide applicator licences

Federal approval is only part of the picture. Each province and territory regulates who may apply pesticides, for whom and where. Depending on your province, you may need:

• A pesticide applicator certificate or licence for commercial or custom application on someone else’s land.
• A separate business or operator licence for the company offering custom spraying.
• Permits or notifications for aerial application, applications near water or residences, or certain products.
• Drone-specific training that some provinces are adding as drone spraying grows.

Farmers spraying their own land may fall under different rules than custom applicators, but the Transport Canada certificate requirements apply to everyone. Contact your provincial agriculture or environment ministry before the season; in Quebec, pesticide use is governed by the provincial Pesticides Act and its regulations. Provincial drone rules more broadly are covered in our pages on Ontario, British Columbia and Alberta.

Mapping, NDVI and crop scouting with small drones

Not every farm drone carries a tank. Small mapping and multispectral drones are often the better first investment, and they fit the ordinary small-drone rules.

• RGB mapping: automated grid flights produce a stitched orthomosaic for drainage planning, stand counts and damage assessment.
• Multispectral and NDVI: sensors that capture red and near-infrared light generate vegetation index maps that highlight stress, nutrient issues or pest pressure before it is obvious from the ground.
• Prescription maps: zone maps from scouting flights can feed variable-rate spreading or targeted spot spraying.
• Livestock and fence checks: quick visual flights save hours of driving on large properties.

Most mapping flights in open rural fields can be done as basic operations if you stay in uncontrolled airspace, keep the drone in sight and stay more than 30 m from bystanders. Large fields can push the drone beyond visual line of sight, so plan flight blocks that keep it visible or use a visual observer within the rules explained in our VLOS and visual observer guide. Calibrate multispectral sensors with a reflectance panel and fly at the same time of day for comparable maps.

Insurance, records and practical safety

Agricultural drone operations carry risks that general farm policies may not cover: drift onto a neighbour’s crop, damage to the drone itself and third-party liability. Ask your broker about aviation liability for drones, pesticide drift or pollution liability, and hull coverage for expensive spray units. Our drone insurance guide covers the basics.

1. Do a site survey of each field: power lines, towers, tree lines, buildings, nearby homes and water.
2. Check wind, temperature and inversion conditions against the label before each load.
3. Brief the crew on roles: pilot, mixer/loader and visual observer.
4. Record each application: product, rate, field, weather, times and crew.
5. Keep flight logs and maintenance records as required for your category; see our record keeping guide.
6. Report incidents as required; see incident reporting.

Frequently asked questions

Can I spray my own field by drone without a certificate?

No, unless the drone weighs under 250 g, which is not realistic for spraying. Every drone of 250 g or more must be registered and flown by a pilot with the right certificate, including farmers working their own land.

Do spray drones need an SFOC in 2026?

Not automatically. Since November 4, 2025, medium drones up to 150 kg can fly in visual line of sight under the advanced rules with the right declarations. An SFOC is still needed for drones over 150 kg and other operations outside the standard categories, so confirm your case with Transport Canada.

Which pesticides can I apply by drone?

Under Health Canada’s June 2026 policy, products registered for conventional aerial application can be applied by drone following the aerial label directions. Products labelled not to be applied by air, or registered only for ground use, cannot be.

Can I spread seed or fertilizer by drone?

Seed and fertilizer are not pesticides, so the pest control product rules do not apply to them, but all the Transport Canada flight rules still do. Check provincial rules for fertilizer application near water.

Do I need a Level 1 Complex certificate for farm work?

Only if you want to fly beyond visual line of sight without an SFOC. Most spray and mapping work can be planned to stay within sight.

Conclusion

Drone spraying in Canada has opened up a great deal since late 2025: medium drones have clear rules and Health Canada now accepts drone application of aerial-registered products. The trade-off is that you must line up every layer yourself: the right certificate and declared drone, the label, the provincial licence and proper insurance. Start with mapping and scouting, build your records, then move into spraying once each permission is in place.
