Seven Canadian composite and carbon fiber partners for UAVs, robotics, and aerospace

Hero: abstract stock image (Lorem Picsum).
Composite work is trust work. You are asking someone to turn expensive cloth and resin into a part that will not turn into a delamination field report six months after first flight.
The firms below range from boutique airfield-adjacent shops to larger structural suppliers. One entry is flagged where our internal directory still marks the row as needing fresh verification. Treat that line item as a prompt to reconfirm scope on your own RFQ, not a finished audit.
1. Spartec Composites
Erin, ON
Spartec advertises more than forty years of carbon fiber and advanced composite design and manufacturing in Canada and the United States, including kit cutting, robotic trimming, tooling, and full-service engineering. Their public materials explicitly call out drone components among their application list.
2. Fibrotek Advanced Materials
Quebec
Fibrotek’s bilingual site describes vertically integrated composite tooling, carbon fiber parts, and precision assemblies for aerospace, automotive, military, and mining customers. They emphasize engineering support from reverse engineering through production.
3. Harwood Custom Composites
Sidney, BC (Greater Victoria)
Harwood operates near Victoria International Airport and advertises more than twenty years of custom composite fabrication, tooling, and design for aerospace, including UAV prototype and production programs. Their site lists five-axis trimming and STC-related quality language, which signals how they think about paperwork, not just layup.
4. Apex Industries (aerospace components)
Moncton, NB
Within a larger Apex organization, the aerospace components group markets aluminum and hard metal parts plus tabletop assemblies with in-house secondary processing. Composite-heavy teams sometimes partner with Apex when metallic interfaces and brackets must match composite tooling datums.
5. Avior Integrated Products
Laval and Granby, QC
Avior publicly positions itself on composite and metallic aerospace structures, fabrication, and assembly. Their site can present a bot challenge to automated fetches, but industry sourcing maps repeatedly list them for structural work in Quebec. Worth a direct technical inquiry if your envelope includes both composite skins and machined fittings.
6. Fleet Canada
Fort Erie, ON
Fleet Canada advertises composites, autoclaves, and five-axis trimming oriented to aerospace-class programs. Our internal supplier sheet still flags them for refreshed diligence on capacity and certifications, so treat this entry as a prompt to verify current scope against your PO terms, not a blanket endorsement.
7. Comtek Advanced Structures
Burlington, ON (Greater Toronto Area)
Comtek advertises composite design, manufacturing, testing, and airworthiness certification from a Burlington facility, with out-of-autoclave manufacturing called out as a strength. They also hold Canadian AMO and DAO approvals for structural repairs on regional aircraft, which tells you how they think about traceability and paperwork, not only about layup speed.
How we picked these
We favored shops that publish UAV or aerospace adjacent examples and list tangible equipment like autoclaves, five-axis trim, or robotic cutting. Where verification is still open on Fleet Canada, we say so out loud. Composites without recent coupon testing are just expensive sculpture.

Filter the vendor directory by industry, province, and fit. If you run a shop that belongs in roundups like this, list your company and we will work through verification with you.
