Postgraduate Diploma in Rotorcraft Gearbox Design — studying from Canada
Canada has a substantial aerospace sector, anchored in Montréal and Québec City, with major manufacturers and suppliers such as Bombardier, Pratt & Whitney Canada and CAE. Ontario's Greater Toronto and Ottawa regions host avionics, satellite and space technology firms, while the Canadian Space Agency coordinates national space programmes, including robotics for the International Space Station. Urban air mobility and drone operations are emerging under Transport Canada's regulatory framework. Engineers in this area typically work on airframe design, systems integration, certification and space mission support.
Fees for Canada: C$1,400 (Canadian dollar), with instalments and employer sponsorship available.

Questions from Canada
Does a SEIUM qualification give me recognition with Canadian professional bodies for aerospace work?
Not automatically. In Canada, engineering is regulated by provincial and territorial associations such as Professional Engineers Ontario, which licence Professional Engineers (P.Eng.). SEIUM qualifications are private and are not official state degrees, so they do not confer P.Eng. status or accreditation. Recognition by employers or other bodies is decided case by case, so check directly with them before enrolling.
Will Canadian aerospace, drone or space employers value this training?
Employer valuation depends on the specific employer and role. Canada has a sizeable aerospace sector, including companies in Quebec, Ontario and Western Canada, and employers generally judge candidates on demonstrated skills, projects and experience. SEIUM's final project can serve as evidence of capability, but whether a private qualification carries weight is for each employer to decide. Discuss your goals with prospective employers.
Can I study this alongside a full-time job in Canada, and what about language?
Yes, the programmes are 100% online, so you can study from home at your own pace around work. Master's programmes are 1,900 hours, postgraduate diplomas 800 hours and specialist courses 300 hours, so plan your weekly time accordingly. Teaching is in English, and each student has an assigned technical tutor. Employer sponsorship and fees payable in instalments may help, depending on your circumstances.

How you'll learn
A 100% online programme on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within each intake, so you can combine it with your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is KISSsoft, Romax, MASTA, ANSYS Mechanical and MATLAB, in free, academic or evaluation versions. Testing is studied through real procedures for transmission test benches, loss-of-oil run tests and oil and particle analysis. Assessment is continuous by module plus the final capstone project.
Standards covered: ISO 6336, AGMA 2001-D04, CS-29, AGMA 911, ISO 281, EN 9100 and MIL-PRF-23699.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
