SFOC: EVLOS, BVLOS & Over-25 kg
SFOC in Canada: EVLOS, BVLOS, and Over-25 kg Drone Operations Explained
Canada's standard RPAS framework — Basic and Advanced operations — covers the majority of commercial drone work. But three categories of operations fall outside that framework and require a Special Flight Operations Certificate (SFOC) from Transport Canada: Extended Visual Line of Sight (EVLOS), Beyond Visual Line of Sight (BVLOS), and operations with aircraft over 25 kg. These are the frontier of commercial drone operations in Canada, and the SFOC process is the gateway to them.
This guide explains what an SFOC is, which operations require one, what Transport Canada expects in an application, and the realistic timelines and requirements for each category. As Canada's authorized DJI Enterprise dealer, Unmanned Canada supports enterprise operators in building programs capable of SFOC-level operations.
An Advanced RPAS certificate is necessary but not sufficient. The SFOC is a separate, operation-specific authorization that must be obtained before flight.
What is a Special Flight Operations Certificate?
An SFOC is a Transport Canada authorization that permits specific drone operations that fall outside the standard RPAS regulatory framework.
An Operation-Specific Authorization from Transport Canada
An SFOC is not a pilot certificate — it is an authorization for a specific type of operation, issued by Transport Canada's Civil Aviation Safety Inspector (CASI) team. Each SFOC defines the approved operation type, geographic area, aircraft, pilot qualifications, and safety mitigations. Operating outside the terms of an SFOC is a regulatory violation equivalent to operating without authorization.
Three Trigger Categories
An SFOC is required for: (1) Extended Visual Line of Sight (EVLOS) operations, where a visual observer extends the pilot's effective line of sight beyond standard VLOS limits; (2) Beyond Visual Line of Sight (BVLOS) operations, where the aircraft is flown beyond unaided visual range; and (3) operations with aircraft over 25 kg maximum take-off weight. All three categories require an SFOC regardless of the pilot's Advanced certification.
Advanced Certificate Is a Prerequisite, Not a Substitute
Pilots conducting SFOC operations must hold a valid Advanced RPAS certificate with a current flight review. The Advanced certificate is a prerequisite for SFOC operations — it does not replace the SFOC. Think of it as: Advanced certificate = licence to fly; SFOC = permission for this specific operation type. Both are required simultaneously.
Standing vs. Single-Operation
Transport Canada issues two types of SFOCs: single-operation SFOCs for a specific date, location, and operation; and standing SFOCs for recurring operations of the same type across multiple locations. Standing SFOCs are more valuable for commercial programs — they reduce the administrative burden of applying for each individual operation. Standing SFOCs require a more detailed application and demonstrated operational track record.
EVLOS: Extended Visual Line of Sight Operations
EVLOS extends the effective operating range of a drone beyond standard VLOS limits by using visual observers positioned along the flight path.
Visual Observers Extend the Pilot's Effective Range
In EVLOS operations, one or more visual observers (VOs) are positioned along the flight path to maintain visual contact with the aircraft when it moves beyond the pilot's direct line of sight. Each VO maintains VLOS with the aircraft within their segment and communicates with the pilot via radio. The aircraft is never truly beyond visual range — it is always within the visual range of at least one qualified observer.
Linear Infrastructure Inspection
EVLOS is most commonly used for linear infrastructure inspection — powerline corridors, pipeline routes, railway lines, and road networks — where the aircraft needs to travel beyond the pilot's direct visual range but the terrain allows observer positioning along the route. EVLOS is a practical middle ground between standard VLOS and full BVLOS for many infrastructure inspection programs.
Observer Qualifications and Communication Protocols
An EVLOS SFOC application must document: the qualifications of all visual observers, the communication protocol between observers and the pilot, the handoff procedure as the aircraft transitions between observer segments, the emergency procedures if communication is lost, and the geographic area and flight path. Transport Canada will assess whether the observer network provides equivalent safety to standard VLOS operations.
Requires Coordinated Multi-Person Teams
EVLOS operations require coordinated teams — the pilot, multiple visual observers, and often a ground crew for logistics. This increases operational cost and complexity compared to standard VLOS operations. For programs where EVLOS is operationally justified (e.g., long-corridor inspection), the efficiency gains over VLOS typically outweigh the coordination overhead. For shorter corridors, standard VLOS with repositioning may be more practical.
BVLOS: Beyond Visual Line of Sight Operations
BVLOS is the most complex and highest-value category of commercial drone operations — and the most demanding from a regulatory and technical standpoint.
Long-Range Autonomous and Semi-Autonomous Operations
BVLOS operations allow the aircraft to fly beyond the unaided visual range of the pilot and any observers — relying on onboard sensors, detect-and-avoid systems, and ground control station telemetry for situational awareness. BVLOS enables long-range corridor inspection, large-area mapping, package delivery, and emergency response operations that are not feasible under VLOS or EVLOS constraints.
Detect-and-Avoid, Reliable Command Link, and Contingency Systems
Transport Canada's BVLOS SFOC requirements are technically demanding. Applicants must demonstrate: a reliable command-and-control link with defined minimum performance standards; a detect-and-avoid (DAA) capability appropriate to the operating environment; defined lost-link procedures and contingency flight termination; and a ground control station with real-time telemetry. The specific technical requirements depend on the operating environment (populated vs. remote, controlled vs. uncontrolled airspace).
The Most Demanding SFOC Category
BVLOS SFOC applications are the most complex in the RPAS regulatory framework. A complete application typically includes: a detailed operations manual specific to BVLOS; a safety case demonstrating equivalent level of safety to manned aviation; aircraft airworthiness documentation; pilot qualification records; communication and contingency plans; and coordination with NAV CANADA for airspace integration. Expect 3–6 months for initial BVLOS SFOC review.
Requirements Scale with Risk
Transport Canada applies a risk-proportionate approach to BVLOS SFOCs. Operations in remote, sparsely populated areas with low air traffic density face lower technical barriers than operations in populated areas or controlled airspace. Many initial BVLOS SFOCs are issued for remote corridor operations — pipeline and powerline inspection in northern or rural Canada — before operators build the track record needed for more complex environments.
The DJI Matrice 400 and Matrice 350 RTK are among the most capable platforms for BVLOS-ready programs in Canada. Both feature redundant command links, real-time telemetry, and integration with DJI's FlightHub 2 ground control platform — key technical foundations for a BVLOS SFOC application. Contact Unmanned Canada to discuss BVLOS program development.
Over-25 kg Operations: Large RPAS and Heavy-Lift Platforms
Aircraft with a maximum take-off weight exceeding 25 kg fall outside the standard RPAS framework and require an SFOC regardless of the operation type.
Higher Mass = Higher Kinetic Energy = Higher Risk
The 25 kg threshold reflects the significantly higher kinetic energy — and therefore higher injury and damage potential — of larger aircraft. Transport Canada requires SFOC authorization for over-25 kg operations to ensure that the additional risk is assessed and mitigated on a case-by-case basis. The SFOC process for over-25 kg operations focuses heavily on aircraft airworthiness, structural integrity, and failure mode analysis.
Heavy-Lift, Agricultural, and Specialized Systems
Over-25 kg platforms in Canada include heavy-lift cargo drones, large agricultural spraying systems, specialized survey platforms with heavy sensor payloads, and some military-derived commercial systems. These platforms are typically purpose-built for specific applications and are not standard commercial off-the-shelf products. The DJI Agras T50 (agricultural sprayer) and similar platforms fall into this category when fully loaded.
Airworthiness Documentation is Central
Over-25 kg SFOC applications must include detailed airworthiness documentation: structural analysis, failure mode and effects analysis (FMEA), maintenance records, and evidence of the aircraft's design and manufacturing standards. Transport Canada may require third-party airworthiness assessment for novel or custom-built platforms. Established commercial platforms with documented airworthiness records (e.g., manufacturer-provided documentation) have a clearer path through the SFOC process.
Typically VLOS in Uncontrolled Airspace for Initial SFOCs
Initial over-25 kg SFOCs are typically issued for VLOS operations in uncontrolled airspace, away from populated areas. As operators build a track record with the platform and demonstrate safe operations, Transport Canada may expand the SFOC to cover more complex environments. Combining over-25 kg with BVLOS in a single SFOC is possible but represents the highest complexity tier of the Canadian RPAS regulatory framework.
Applying for an SFOC: What to Expect
The SFOC application process requires significant preparation. Understanding what Transport Canada expects before you start will save time and improve your chances of approval.
Core Application Components
- Operations manual — detailed procedures specific to the SFOC operation type (EVLOS, BVLOS, or over-25 kg)
- Safety case / risk assessment — demonstrates equivalent level of safety to the standard RPAS framework
- Aircraft documentation — registration, airworthiness records, maintenance logs, and manufacturer specifications
- Pilot qualifications — Advanced certificate, current flight review, and operation-specific training records
- Emergency and contingency procedures — lost-link, lost-control, and emergency landing protocols
- Insurance documentation — commercial liability coverage appropriate to the operation type
Timeline and Process Expectations
- EVLOS SFOC — typically 4–8 weeks for a well-prepared application; longer for novel operations
- BVLOS SFOC — typically 3–6 months for initial application; faster for subsequent renewals
- Over-25 kg SFOC — typically 6–12 weeks depending on aircraft documentation completeness
- Standing SFOC — longer initial review but covers recurring operations; most valuable for commercial programs
- Submission lead time — submit at least 30 days before planned operations for simple SFOCs; 90+ days for BVLOS
- CASI engagement — proactive pre-application consultation with your regional CASI can significantly reduce review time
Transport Canada's SFOC review process is iterative — expect questions and requests for additional information. Engaging your regional Civil Aviation Safety Inspector (CASI) before submitting your application is strongly recommended. A pre-application meeting can clarify expectations, identify gaps in your documentation, and significantly reduce the overall review timeline.
Frequently Asked Questions
Can I fly BVLOS with just my Advanced certificate?
No. An Advanced RPAS certificate is a prerequisite for BVLOS operations but does not authorize them. BVLOS operations require a specific SFOC issued by Transport Canada for the operation type, aircraft, geographic area, and pilot. Flying BVLOS without an SFOC is a serious regulatory violation regardless of the pilot's certification level.
How long does an SFOC last?
SFOC duration varies by type. Single-operation SFOCs cover a specific date or date range. Standing SFOCs are typically issued for 12–24 months and must be renewed before expiry. Renewal applications for standing SFOCs with a clean operational record are generally processed faster than initial applications. Build renewal timelines into your program calendar to avoid operational gaps.
What is the difference between EVLOS and BVLOS?
In EVLOS operations, the aircraft is always within the visual line of sight of at least one qualified observer — the pilot or a visual observer positioned along the flight path. In BVLOS operations, the aircraft flies beyond the unaided visual range of all observers and relies on onboard sensors, telemetry, and detect-and-avoid systems for situational awareness. BVLOS is significantly more technically demanding and carries higher regulatory requirements than EVLOS.
Do I need an SFOC if my drone weighs exactly 25 kg?
The threshold is aircraft over 25 kg maximum take-off weight (MTOW). An aircraft with an MTOW of exactly 25 kg falls within the standard RPAS framework and does not require an SFOC on the basis of weight alone. An aircraft with an MTOW of 25.1 kg requires an SFOC. Always use the manufacturer's published MTOW — not the empty weight or typical operating weight — to determine which framework applies.
Can I get a standing SFOC for BVLOS on my first application?
It is possible but uncommon. Transport Canada typically issues initial BVLOS SFOCs as single-operation or limited-scope authorizations to allow operators to demonstrate safe operations before issuing a broader standing SFOC. Building a track record with single-operation SFOCs — and maintaining detailed flight records — is the most reliable path to a standing BVLOS SFOC.
