Side hustle for F · McGill Macdonald

Get restaurants to pay you to do their homework.

A 2026 game-plan for F to launch a sustainability side hustle in Montreal — no startup capital, no quitting school, no jargon. Read this before Friday.

1 Why this works right now

New Canadian rules force every restaurant to back up any green claim with evidence. Most owners don't have time to read the rules. You do the reading, hand them a 1-page proof, and they pay you $1,500.

The fine print. Since June 2025, the Competition Bureau can fine a restaurant up to $10M or 3% of global revenue for saying "eco-friendly" or "compostable" without proof. That's the fear you're selling against.

Three rules that just landed

RuleWhat it means for a restaurant
Federal greenwashing rules (Jun 2025)Every "carbon neutral," "eco-friendly," "compostable" claim needs evidence.
Federal plastic ban (Dec 2025)No more bags, cutlery, stir sticks, Styrofoam containers.
Quebec packaging fee (RRVPE 2023)They pay extra fees on packaging — and need someone to track it.

Why nobody's doing this yet

Big consulting firms won't take a 30-seat restaurant — min tab is $20k. Quebec specialty firms focus on factories. The door is wide open. Only 17% of Quebec SMEs are doing any of this work right now (QNP 2024 barometer). That's 83% of the market sitting still.

2 Who's buying

Your beachhead: owners of 1–3 location restaurants in Montreal who already post a green story anywhere — Instagram, menu, Uber Eats, website. They're scared of the fine, they don't have a sustainability person, and they'd pay $1,500 to know they're safe.

Perfect fit

Mile End / Plateau / Verdun indie restaurants

Owner-operator, 20–80 seats, already brag about local sourcing on Instagram. They care but never wrote the policy down.

Perfect fit

Food co-ops & collectives

Member-owned, board structure, get grants for sustainability audits. Slow to say yes, but big checks once they do.

Stretch

Local cafés & bakeries

Smaller checks ($500–$1k scope), but easier to close in volume. Good for filling the calendar.

Stretch

Microbreweries & butcher shops

Same regulatory exposure, slightly higher revenue per ticket. Niche but easier to differentiate.

3 What you sell

Three packages. Pick one when a client asks, "so what do you actually do?"

Starter

Compliance Sweep

$1,500 one-time

You show up, check their website + menu + packaging, give them a 5-page "you're safe / fix this" memo.

Best for: owners who need peace of mind before the regulator shows up.

~15 hrs · 2 weeks to ship
Pro

Decarbonization Roadmap

$5,000–9,000 one-time

The full Sweep + a carbon footprint + a 3-year plan to cut it + you fill out the Quebec subsidy form (up to 75% paid by the gov).

Best for: owners who want to brag about sustainability on a billboard.

~50 hrs · 6 weeks to ship
Retainer

Sustainability Lead

$1,200–2,500 /mo · 6-month min

You become their sustainability person. Annual report, regulatory updates, on-call for greenwashing questions.

Best for: restaurants applying for green loans or B-Corp cert.

Ongoing · bills every quarter
Heads up — one framing trap. Don't call yourself a "consultant" if you haven't graduated. "Sustainability analyst" is friendlier. For any carbon-number you sign off on, co-sign with a licensed engineer or biologist. The fine is on the restaurant, not on you, but the reputational hit is on you.

4 How you price

Don't sell hourly. Restaurants don't want a meter running. Sell the deliverable.

What you doYou'll chargeQuebec market rateYou're at
1-pager claim audit$1,500$2,000–3,000Cheap + loadable
Full carbon inventory + roadmap$5,000–9,000$8,000–15,000Boutique pricing
Monthly retainer$1,500/mo$2,500–5,000/moStudent-discount; raise after 3 clients
Subsidy application (only)$1,500$2,500Easy upsell
Hourly (avoid)$39–43/hr median, $28–$69 rangeDon't do it

Raise prices every 5 clients. First 3 are at $1,500 to get case studies. Client 4–10 go to $2,500. After 10, $3,500+. This is a market-notebook, not a friend discount.

5 First 5 clients in 90 days

Skip the cold email. Walk in. Restaurants see sales reps all day — one walking in with a 1-page "you're 2026-ready?" scorecard is memorable.

1
Week 1 — Apply to Dobson's "Innovation in Sustainability Lean" cohort. Free mentorship, real McGill credibility, ~$0 cost. October 1 intake. Apply today, not tomorrow.
2
Week 1 — Build one paper slide. A 12-question "Is your restaurant 2026-ready?" scorecard. Email 3 Macdonald profs to ask for a 5-min review. Use their name on the slide.
3
Week 2 — Sell 1 to a friend-of-friend. Easier than cold outreach. Offer $1,500 for a Compliance Sweep. Don't go below that, even for friends.
4
Week 3–6 — Walk 15 restaurants. Mile End, Plateau, Verdun. 5 per day. Bring the scorecard. Don't pitch — ask one question: "Is your packaging 2026-rule-clean?" Then listen.
5
Week 7–10 — File one Quebec subsidy for a client. Programme ÉcoPerformance covers up to 75% of small projects. If you file it and the client gets $5k from the gov, they'll never leave you.
6
Week 11–13 — First retainer + case study. Convert your best client into a monthly agreement. Write up the win. Now you have proof.
By week 13: 5 clients, ~$18k revenue, ~80 hrs total.

6 Year-1 money math

Here's the realistic take. Not VC fantasy — student-with-30-hrs-a-week-in-summer math.

Realistic

Year 1 — solo, school-year cadence

$50–80k

20 clients @ $2.5k avg. 8 hrs/wk semester, 30 hrs/wk summer.

Stretch

Year 2 — graduate + hire 1 junior

$120–180k

Same density, doubled if you hire a Macdonald RRM junior at $25/hr to do data entry.

8 Things that can bite

Be honest about what kills this. Pick mitigations before they happen.

RiskWhat goes wrongHow you handle it
You sign off on a bad numberRestaurant gets fined. You get blamed.Always use GHG Protocol methodology. Disclaimer on every page. Co-sign with a licensed pro for Scope-1.
Restaurant closes30% annual turnover. You lose a retainer.Always sell 6-month minimums. Don't bet on one client.
Quebec subsidy takes 6 mo to payClient blames you.Pre-finance via your own cash flow OR partner with a subsidy-broker firm (e.g. DxE Conseil).
You graduate and leave MontrealPipeline dies.Hire a junior from the Macdonald RRM cohort — they're instantly qualified. Train them on your templates.
Competitor copies youAnother student does the same thing.Move first. Publish case studies. Get the Dobson alumni badge.
You oversell your expertiseOwner asks something you don't know.Say "I'll pull the regulation and get back to you tomorrow." Never fake it.

9 The 30-day launch checklist

Print this. Tick the boxes. Don't move on until each one is done.

Day 1–2 — Apply to Dobson's Innovation in Sustainability Lean. Oct 1 intake. The deadline is the deadline.
Day 3–5 — Build the "Is your restaurant 2026-ready?" 12-question scorecard. Use Canva (free). One page. Bilingual.
Day 6–7 — Email 3 Macdonald NRS profs for a 5-min review. "I'm launching a sustainability audit service for restaurants. Would you review my 1-page scorecard?"
Day 8–10 — Walk 5 restaurants in Mile End / Plateau. Don't pitch. Ask "Is your packaging 2026-rule-clean?" Listen. Take notes.
Day 11–14 — Register as travailleur autonome. Set up Wave. Draft a bilingual service agreement (Dobson Legal Clinic).
Day 15–20 — Pick 1 client. Propose Compliance Sweep at $1,500. Friends-of-friends first. Get a case study.
Day 21–30 — Deliver the Sweep. Ask for a referral. Referrals close faster than cold walks. Even one referral-to-close is a 5× win.
Mayday check. If you finish day 30 with no paying client, walk 5 more restaurants the next week. Don't quit your semester. The market is real — but rhythm matters more than hustle.
