Hook: the drone at the door

A company wants to deliver packages by drone in your town. It sounds exciting: faster deliveries, fewer trucks. But questions pile up fast. Is it legal to fly over houses? What if a drone's camera films people in their backyards? Who loses a job? How noisy will the sky be? What happens to all those batteries?

No technology is developed or used in a bubble. Its development and application are shaped by legal, ethical, social, economic and environmental considerations. Looking through these five lenses helps you decide whether a technology is a good idea, and how to make it better.

Look at any technology through five lenses. Each lens raises different questions, and a good decision considers all five.

1. Legal considerations

Laws and regulations limit what can be made, sold and used, mainly to protect people:

Safety standards and certification: electrical products sold in Canada must be certified by an accredited organization (look for marks such as CSA or cUL). Health Canada can order recalls of unsafe consumer products.
Building codes: the Ontario Building Code sets rules for construction, and many projects need a building permit and inspections.
Transportation rules: in Canada, drones that weigh 250 g or more must be registered with Transport Canada and their pilots need a drone pilot certificate.
Accessibility: the Accessibility for Ontarians with Disabilities Act (AODA) sets accessibility standards for many organizations.
Privacy: Canadian privacy laws limit how businesses collect and use personal information.
Labelling: most prepackaged consumer products sold in Canada need labels in English and French.
Intellectual property (IP) protects ideas and creations:
A patent protects an invention that is new, useful and not obvious, for up to 20 years from filing. In exchange, the inventor publishes how it works.
Copyright protects original works such as designs, photos, music and code; in Canada it generally lasts for the creator's life plus 70 years.
A trademark protects names, logos and slogans that identify a company's products (™ for a claimed mark, ® for a registered one).

A patent gives an inventor up to 20 years of protection. After it expires, anyone can use the invention, which helps new innovations build on it.

2. Ethical considerations

Ethics asks: Is it right? Is it fair? Who could be harmed? Laws often lag behind new technology, so designers must think about ethics themselves.

Privacy: smart speakers, doorbell cameras and apps collect data. Do users know and agree?
Fairness: artificial intelligence (AI) systems trained on unbalanced data can treat some groups unfairly.
Honesty: AI can create realistic fake images, voices and videos (deepfakes).
Responsibility: are products made to last and to be repaired, or designed to be thrown away? Are workers in the supply chain treated fairly?
Animals: in 2023, Canada passed a law banning the testing of cosmetics on animals, an ethical issue that affects the hairstyling and aesthetics industry.

3. Social, 4. economic and 5. environmental considerations

Social: How does the technology change how people live, work, learn and connect? Who benefits, and who might be left out (for example, people without internet access or people with disabilities)? Does it fit the community's values and culture?

Economic: What does it cost to develop, make and buy? Will people pay for it? Will it create or replace jobs? Does it help local businesses or compete with them? A technology can be a great idea and still fail if it is too expensive.

Environmental: What resources and energy does it use? What emissions and waste does it create, from raw materials to disposal? Can it be repaired, reused or recycled?

Trade-offs

These five considerations often pull in different directions. A cheaper material may be worse for the environment; a privacy feature may raise the price. Good designers look for solutions that balance the trade-offs, and they explain their choices.

Worked example

Let's analyse medical-supply drones for remote communities

Many communities in Northern Ontario can be reached only by air for much of the year, or by winter roads when the ground is frozen. A health agency proposes using drones to deliver medicines and lab samples. Analyse the idea with all five lenses.

Legal: drones must be registered and flown by certified pilots under Transport Canada rules; flights beyond the pilot's line of sight need special permission; medicines must be handled according to health rules.
Ethical: the community must be consulted and must agree; any data or images collected must be kept private; patient information must be protected.
Social: faster access to medicine and test results could improve health; but it must not replace face-to-face health care or local jobs without the community's agreement.
Economic: drones and pilots cost money, but each flight may cost less than chartering a plane; local people could be trained as drone operators (new jobs).
Environmental: small electric drones use less fuel than planes for small loads; batteries must be recycled; noise and wildlife disturbance should be checked.
Decision: the idea looks promising if it is developed with the community, meets the legal rules and is tested carefully.

Using all five lenses shows benefits (faster care, lower cost per flight, less fuel) and conditions (consultation, privacy, safety rules, battery recycling).

Just for fun

Riddle: You can own me, sell me, protect me and even steal me, but you can never touch me. What am I?

An idea, or intellectual property.

Hands-on activity

Legal detective at home

You need: five products with labels or packaging (an appliance, a toy, a food package, a tool, a phone charger), paper, a pencil.

Look for and record any certification marks (CSA, cUL, ULC), trademarks (™ or ®), patent notices ("Pat." or "Patent"), copyright symbols (©), warning labels and French and English text.
For each mark, write which consideration it shows (legal, ethical, social, economic, environmental) and why it is there.
Choose one product and write a short five-lens analysis: one question and one answer for each lens.
Discussion with someone at home: Should companies be allowed to make products that cannot be repaired? Write down both sides and your own view.

Your turn

Name the five considerations that affect technology.

How long can a Canadian patent protect an invention?

What does the ® symbol mean?

Give one ethical question about smart doorbell cameras.

Name one Ontario or Canadian law that affects technology.

Give one economic consideration for a company designing a new snowblower.

More practice: warm-up

Which consideration asks "Is it right and fair?"

What does copyright protect?

What do drones that weigh 250 g or more need in Canada?

Which consideration is about resources, energy and waste?

Why do many Canadian products have English and French labels?

More practice: on your own

Why does a patent require the inventor to publish how the invention works?

Give an example where economic and environmental considerations pull in different directions, and suggest a balance.

How can an AI system be unfair, and what could designers do about it?

Explain how accessibility is both a legal and a social consideration.

A student wants to sell T-shirts with a famous sports team's logo they found online. What legal issue is involved?

Challenge

Use all five lenses to evaluate e-scooter sharing in a city.

"If it's legal, it's ethical." Do you agree? Use a technology example to explain.

A company could make a kettle last 15 years with replaceable parts, or 4 years at a lower price. Analyse the choice using economic, environmental and ethical considerations, and recommend one.

For parents and teachers

The five lenses are a lifelong decision-making tool. Try them at dinner on a current news story about a technology (AI, electric cars, a new app). Ask your teen to argue the side they disagree with: it builds strong reasoning.

Common difficulties: confusing ethical with legal (something can be legal but unfair), and giving one-sided answers. Encourage "on one hand... on the other hand... so I conclude...". In the activity, safety and certification marks are usually on the back or bottom of appliances and chargers; your teen should not unplug or open anything to find them.
