In Ontario it’s against the law to sell or serve liquor to anyone who **is or appears to be intoxicated**. Spotting the signs early lets you slow things down before you have to cut someone off. This guide follows the AGCO’s own information sheet.

## The signs to watch for

People react differently, and signs can show up in any order or in clusters. **One sign alone doesn’t confirm intoxication**, so keep watching.

*Paraphrased from the AGCO information sheet on recognizing intoxication.*
| Sign | What it looks like |
| --- | --- |
| Speech volume | Much louder or softer than the situation calls for, or swinging between the two |
| Speech pace | Too fast, too slow, or switching between rushed and slow |
| Slurring | Stumbling over words or running them together |
| Fine motor control | Fumbling with money, cards, phones or paper; misjudging distance |
| Gross motor control | Swaying, stumbling, bumping into people or furniture, arms out for balance |
| Alertness | Slow to respond, losing the thread, needing questions repeated |
| Sweating | More than the room temperature explains |
| Eyes | Bloodshot; with cannabis, possibly eyelid tremors or dilated pupils |
| Breathing | Slower or shallower than normal |
| Tiredness | Drowsy, heavy or closed eyes, a fixed or glassy stare |

Alcohol and cannabis are both depressants, and many signs look the same. It’s fair to ask a guest whether they’ve eaten, or have been drinking or using cannabis somewhere else.

## What to do at each stage

1. **First signs.** Keep a close eye on the guest. Offer food, water and low- or no-alcohol drinks to slow things down.
2. **A few signs.** Keep monitoring closely and keep steering them toward food and lower-alcohol or non-alcoholic choices.
3. **Multiple signs.** Stop serving alcohol, whatever the circumstances. Make sure they have a safe way home, and call police if necessary.

## How to stop service without a scene

- Be discreet, calm and polite. Speak to the guest, not about them.
- Make it about the law, not the person: you can’t serve someone who appears intoxicated.
- Offer water, a non-alcoholic drink or food.
- Tell your manager and the rest of the team so no one else serves them.
- Help with a safe ride: a sober friend, a taxi or transit. If they insist on driving, call police.

> The AGCO recommends that managers tell staff, in writing, that management will **back them** when they refuse service. If your workplace doesn’t have a house policy, ask for one.

## Why it matters

- The licensee must not permit intoxication on the premises or in adjacent areas it controls (O. Reg. 746/21, s. 43).
- If someone is served to the point of danger and then injures someone, the injured person can claim compensation from the seller (LLCA, s. 52).
- Door staff should refuse entry to anyone who already appears intoxicated.
- Delivered liquor can only be handed to someone who doesn’t appear intoxicated.

## Prevention beats refusal

- Market food, including low-cost snacks, and promote non-alcoholic drinks at good prices.
- Limit the number of drinks sold to one person at a time and discourage drinking games.
- Have a separate policy for bottle service: pour spouts and staff or security nearby.
- No drinking on the job, for staff or managers.
