right to repair
The idea, now partly in law, that owners and independent shops should be able to fix devices.
technological protection measure (TPM)
A digital lock that controls access to or use of software or a device.
interoperability
The ability of programs, devices or components to work together.
planned obsolescence
Designing a product to stop working or become outdated sooner than it needs to.

collection rate
The amount of a product collected for proper management, as a percentage of a stated reference amount.

Who is doing something about it?

In Grade 11 (ICS3U, Where Old Computers Go) you met Ontario's producer-responsibility rules for electronics, the regulator RPRA, Computers for Schools Plus, battery and cartridge programs, and the Basel Convention. Expectation D1.2 asks you to investigate and report on government and community initiatives. That is more than listing them: an investigator asks what kind of initiative it is, whether it works, who it reaches and what it costs, and backs each answer with evidence.

Four kinds of sustainability initiativesRules (regulation)Producer responsibility (Ontario EEERegulation); right-to-repair laws;planned-obsolescence ban (Québec)Money (economic)Recycling fees built into prices;grants for refurbishing programs;buy-back and trade-in creditsInformationEfficiency labels (ENERGY STAR);repairability and environmentalproduct reports; awareness campaignsCommunity and voluntaryMunicipal depots; repair cafés;refurbishers such as Computers forSchools Plus; cartridge returns
Initiatives fall into four broad kinds. Many real programs mix several kinds (for example a regulation that requires producers to pay for collection).

Recent government initiatives (as of October 2026)

Ontario: producer responsibility. Under the Electrical and Electronic Equipment (EEE) Regulation (O. Reg. 522/20, made under the Resource Recovery and Circular Economy Act, 2016), producers of information technology, telecommunications and audio-visual equipment have been responsible for collecting and managing their products at end of life since January 1, 2021. The Resource Productivity and Recovery Authority (RPRA) registers producers and enforces the rules. This is called extended producer responsibility (EPR): because producers pay to deal with their products, they have a reason to design them to be easier to recycle.

Canada: right to repair. On November 7, 2024, two federal bills amending the Copyright Act received Royal Assent:

  • Bill C-244 allows people to get around a technological protection measure (a digital lock) when the purpose is only to diagnose, maintain or repair a product.
  • Bill C-294 allows getting around a digital lock to make a program or device interoperable (able to work) with other programs, devices or components.

Before these changes, a digital lock could legally block an independent repair shop from fixing a device even if the owner wanted it fixed.

Québec: planned obsolescence. Québec's Bill 29, which received assent on October 5, 2023, bans selling goods designed to become obsolete, and phases in requirements that make repair easier, require spare parts to be available for a reasonable time, and add a warranty of good working order for certain goods.

Elsewhere. The European Union requires a USB-C charging port on many portable electronics sold there (for most devices since December 28, 2024), so one charger fits many devices and fewer chargers are made and thrown away.

In a circular economy, devices are designed to be repaired, kept in use, refurbished, and finally recycled so their materials return to making new products. The repair and refurbish steps (green boxes, with dashed arrows) put devices back in use and keep the most value.

Community initiatives

  • Municipal depots and collection events accept electronics, batteries and cartridges.
  • Refurbishers: Computers for Schools Plus refurbishes donated devices for schools, libraries, not-for-profits, Indigenous communities and eligible low-income Canadians; private companies refurbish and resell with warranties.
  • Repair cafés and community repair events: volunteers help people fix electronics, clothes and household items for free, teaching repair skills.
  • Printer cartridge return programs run by manufacturers and some retailers.
  • School initiatives: eco-clubs, device lending libraries, and student IT teams that repair school equipment.

How to evaluate an initiative

Use evidence for each criterion:

  1. Effectiveness: what measurable result does it produce? (tonnes collected, devices refurbished, a percentage collected or recovered)
  2. Reach and access: who can use it? Is it available in rural and northern communities, and to people without a car?
  3. Cost and who pays: taxpayers, producers, or consumers through fees?
  4. Equity: does it help people who most need devices or face the most pollution?
  5. Unintended consequences: for example, collected e-waste shipped to places without safe recycling.
  6. Accountability: are results published and checked by someone independent?

A useful measure is the collection rate: the mass collected as a percentage of a reference amount (for example, the mass of products sold in earlier years, or the amount of e-waste generated). Always say which reference was used, because different choices give different percentages.

Worked example

Example 1: Comparing two initiatives with a weighted score

A student compares a municipal e-waste depot and a community refurbishing program. Scores (1 to 5): depot: effectiveness 4, reach 3, cost 4, equity 2; refurbisher: effectiveness 3, reach 2, cost 3, equity 5. Weights: effectiveness 0.4, reach 0.2, cost 0.2, equity 0.2. Which scores higher?

  1. Depot: 0.4 × 4 + 0.2 × 3 + 0.2 × 4 + 0.2 × 2 = 1.6 + 0.6 + 0.8 + 0.4 = 3.4.
  2. Refurbisher: 0.4 × 3 + 0.2 × 2 + 0.2 × 3 + 0.2 × 5 = 1.2 + 0.4 + 0.6 + 1.0 = 3.2.
  3. The depot scores slightly higher with these weights.
  4. If equity were weighted more heavily (say 0.4, with effectiveness 0.2), the refurbisher would win: depot 0.8 + 0.6 + 0.8 + 0.8 = 3.0; refurbisher 0.6 + 0.4 + 0.6 + 2.0 = 3.6.

Depot 3.4, refurbisher 3.2. The ranking depends on the weights, so a good report states its weights and explains why it chose them.

weights = {"effectiveness": 0.4, "reach": 0.2, "cost": 0.2, "equity": 0.2}
programs = {
"Municipal depot": {"effectiveness": 4, "reach": 3, "cost": 4, "equity": 2},
"Refurbisher": {"effectiveness": 3, "reach": 2, "cost": 3, "equity": 5},
}
def score(ratings, weights):
return sum(weights[c] * ratings[c] for c in weights)
for name, ratings in programs.items():
print(f"{name}: {score(ratings, weights):.1f}")
weights["equity"], weights["effectiveness"] = 0.4, 0.2
print("With equity weighted 0.4:")
for name, ratings in programs.items():
print(f"{name}: {score(ratings, weights):.1f}")

A weighted decision matrix as dictionaries. Changing the weights changes the ranking.

Municipal depot: 3.4
Refurbisher: 3.2
With equity weighted 0.4:
Municipal depot: 3.0
Refurbisher: 3.6

Writing your investigation report

A strong report on an initiative has: a summary; background (the problem it addresses); how it works (who runs it, who pays, who can use it); evidence of results with sources and dates; an evaluation using the criteria above; recommendations; and a reference list. Use the organization's own reports, government web pages and news sources, and note when a source has an interest in looking good.

Just for fun

Why did the old phone charger feel left out after the USB-C rule?

It just couldn't find a connection anymore.

Hands-on activity

Investigate a local initiative

You need: internet access, a phone or email (optional), and a word processor or paper.

  1. Choose one initiative you could use: your municipality's e-waste program, a retailer take-back program, a refurbisher, a repair café, or a cartridge return program.
  2. Find out: who runs it, who pays, what it accepts, where and when, and what happens to the items. If the website doesn't say, write or call with polite questions (with a parent's permission).
  3. Look for evidence of results (annual reports, numbers collected or refurbished) and note the date of each figure.
  4. Score it on the six criteria and run the weighted-score program with your own weights.
  5. Write a one-page report using the structure in the tip, with at least two recommendations.

What to look for: facts with sources and dates, a clear statement of who pays and who is reached, weights explained, and recommendations that follow from the evaluation.

For parents and teachers

Big idea: D1.2 asks students to investigate and report on government and community initiatives that encourage environmental stewardship. Grade 11 introduced Ontario's programs; this lesson adds recent laws (federal right-to-repair amendments of 2024, Québec's 2023 planned-obsolescence law) and, most importantly, how to evaluate an initiative with evidence.

How to help: Help your teen choose a local program you could actually use, and, if they contact it, review their message for politeness and clarity first. Ask "Who pays for this?" and "How do they know it works?"

Common difficulties:

  • Listing programs without evaluating them.
  • Quoting figures without dates or sources, or trusting an organization's own claims without checking.
  • Confusing recycling (recovering materials) with reuse and refurbishing (keeping the device working).
  • Laws and programs change; the facts here are current as of October 2026.
