Blue box, green bin, black bin: a no-nonsense guide to Canadian recycling

Here's the first thing to know about recycling in Canada: it's run by your municipality, not the country. Toronto, Vancouver and rural Saskatchewan all have different rules, bins and schedules. But the core three-stream system is recognisable almost everywhere — and the most common mistakes are remarkably consistent too.

The blue box (or blue bin): containers

The blue box takes containers: plastic bottles, jugs, tubs and lids, glass bottles and jars, aluminum and steel cans, foil trays, milk and juice cartons, and empty aerosol and paint cans in many programs. The universal rules: containers must be empty and rinsed — a quick swill is enough — and placed in the bin loose, never bagged. Bagged recyclables get pulled at the sorting facility and landfilled, because workers can't safely open them. Increasingly, provinces are shifting recycling costs to producers — Ontario's transition to producer-run collection completed in 2026 — but for residents the bins and sorting rules stay much the same.

Paper and cardboard: the second stream

Many cities run a separate stream for paper: newspapers, flyers, magazines, office paper, envelopes and flattened corrugated cardboard. In Toronto it rides in the same blue bin; in other cities it's a grey box or a fibre bag. Either way, the same contaminants apply: greasy pizza boxes, waxed paper, paper towels and shredded paper don't belong (though many programs let you compost the greasy cardboard). Break boxes down flat — a bin full of intact boxes is a bin that's mostly air.

The green bin: organics

Where green bin programs exist — most of Ontario, Metro Vancouver, Montreal's growing network and many other cities — they take food scraps, plate scrapings, coffee grounds, paper towels, napkins and often small amounts of yard waste. Unlike backyard composting, municipal green bins usually accept meat, bones, dairy and shells, because the material goes to industrial composting or anaerobic digestion. Line the bin with newspaper or a certified compostable bag — never a regular plastic bag, which contaminates the finished compost. If you don't have curbside organics, backyard composting handles fruit and vegetable scraps, eggshells and yard trimmings well.

What's left for garbage — and what's never garbage

After containers, paper and organics, the garbage stream should be small: soft plastics (in most provinces), broken ceramics, diapers, vacuum contents and composite packaging like chip bags and coffee pods. But some things are never garbage: batteries, electronics, paint, propane tanks and medications all have dedicated — usually free — drop-off programs. In British Columbia, Recycle BC depots also take soft plastics, foam packaging and flexible packaging that curbside bins refuse.

The mistakes that cost everyone

• Bagging your recycling: the single most common error. Everything goes in loose.
• Black plastic: sorting machines can't see it. Takeout containers and meat trays in black plastic usually belong in the garbage.
• Food in containers: a half-full jar of sauce can contaminate a whole bale of paper. Empty and rinse.
• Wishcycling: garden hoses, clothes, toys and electronics in the blue bin tangle machinery and cause shutdowns. When in doubt, check your city's waste wizard — nearly every municipality has an online lookup tool.

Sorting right at home keeps the whole system working — and with schedules that alternate weekly or biweekly by stream, the other half of the battle is getting the right bin out on the right night. BinMinder reminds you the evening before every collection.
