Arguments for and Against Trade Barriers

Studying trade barriers demands more than abstract theory, because protectionist policies affect communities differently and spark vivid discussions about fairness and trade-offs. Active learning lets students wrestle with real stakes through debate, role-play, and data analysis, making the economic and political consequences of tariffs tangible for each learner.

Activity 01

Philosophical Chairs45 min · Whole Class

Fishbowl Debate: Protectionism Arguments

Select 8-10 students for inner circle to debate infant industry and national security cases; outer circle observes and notes strengths. Rotate roles after 15 minutes. Debrief whole class on persuasive evidence.

Analyze the infant industry argument for protectionism.

Facilitation TipDuring the Fishbowl Debate, assign a student inside the circle to track whether each speaker cites economic or political reasons, so the class can see patterns in arguments.

What to look forPose the question: 'Should Canada protect its auto manufacturing industry with tariffs, even if it means higher car prices for consumers?' Have students take sides and present one economic and one political argument to support their position.

Philosophical Chairs30 min · Pairs

Pairs Role-Play: Policy Advisors

Pair students as advisors to government: one pushes free trade, one barriers. Prepare 2-min pitches with Canadian examples like lumber disputes. Switch roles and critique partner.

Critique the national security argument for imposing trade barriers.

Facilitation TipIn Pairs Role-Play, give each pair a timer and a template with four boxes for claims, evidence, stakeholder impact, and policy recommendation to keep the discussion focused and equitable.

What to look forAsk students to write down one specific industry where the infant industry argument might apply in Canada today. Then, have them briefly explain why that industry might need protection.

Small Groups Cost-Benefit Chart: Tariff Scenarios

Groups receive scenario cards on tariffs (e.g., steel imports). Chart winners/losers for jobs, prices, exports using provided data. Present findings and vote on policy.

Evaluate the overall economic welfare implications of free trade versus protectionism.

Facilitation TipFor the Small Groups Cost-Benefit Chart, provide a blank table with columns for direct costs, indirect costs, benefits, and stakeholder groups to guide structured analysis.

What to look forPresent students with a short scenario describing a country imposing tariffs on imported steel. Ask them to identify whether the primary justification is likely the infant industry argument or the national security argument, and to explain their reasoning in one sentence.

Gallery Walk35 min · Small Groups

Gallery Walk: Argument Stations

Set up stations for each argument with pros/cons cards. Small groups rotate, add sticky notes with evidence or critiques. Discuss class patterns.

Analyze the infant industry argument for protectionism.

Facilitation TipAt Argument Stations during the Gallery Walk, place a sticky note pad at each station so students can post clarifying questions or counterpoints that peers address as they rotate.

What to look forPose the question: 'Should Canada protect its auto manufacturing industry with tariffs, even if it means higher car prices for consumers?' Have students take sides and present one economic and one political argument to support their position.

A few notes on teaching this unit

Experienced teachers start with concrete examples before theory, using case studies from Canada’s softwood lumber dispute or steel tariffs to ground abstract arguments in lived experience. They avoid framing free trade as universally good or bad, instead scaffolding scenarios where students must defend positions they may personally oppose, which builds analytical flexibility. Research suggests that when students embody specific stakeholders in role-plays, they retain economic concepts longer and show greater empathy for opposing views.

By the end of these activities successful students will confidently articulate protectionist justifications, quantify costs and benefits of tariffs, and recognize how political pressures shape economic policy. They will also practice weighing short-term protection against long-term efficiency, showing nuance in their arguments.


Watch Out for These Misconceptions

  • During Fishbowl Debate, watch for students claiming trade barriers always save domestic jobs long-term.

    Use the Fishbowl Debate’s inside-circle role to prompt speakers to specify time frames and trade-offs, and have the class tally examples where protection led to higher prices or inefficiencies.

  • During Pairs Role-Play, watch for students assuming free trade benefits everyone equally.

    Require each pair to list at least two stakeholder groups with opposing outcomes, then share one pair’s list with the class to highlight inequities.

  • During Pairs Role-Play, watch for students believing infant industries mature quickly without permanent protection.

    Ask policymaker pairs to negotiate a sunset clause for their tariff proposal and defend whether political pressure might remove it, using their role cards to track arguments.
