6 Things Americans Do in Canada That Instantly Give Them Away

Americans are heading north again. Statistics Canada reported that US resident trips to Canada totalled 3.0 million in June 2026, up 6.1% from the same month in 2025, the fifth straight monthly increase.[1] That follows a stretch when trips by US residents fell, a downward trend that began in February 2025.[2]

The two countries look alike at a glance, share a very long border, and speak mostly the same language. That’s exactly why the small differences stand out. Locals tend to notice a handful of habits before a visitor says a single word.

Paying With US Dollars Like It’s a Given

This one comes up first because it happens at the register. Both countries call their money the dollar, yet one US dollar isn’t equal to one Canadian dollar, so you should expect to use Canadian currency, with a few exceptions.[3] Handing over a US bill and expecting an even swap is a quick way to reveal where you’re from.

Some businesses will take it. Certain tourist area businesses near the US border may accept USD, but CAD is standard everywhere.[4] Even when a shop agrees, the exchange rate is usually set in the shop’s favour, not yours.

The same goes for tips. Tipping in Canadian dollars matters, because otherwise service workers get cash they can’t use without paying high exchange fees.[5] One 2026 visitor guide adds that paying or tipping in US dollars means the worker absorbs the exchange loss.[6]

Saying Yes When the Card Terminal Offers Your Home Currency

Many American visitors tap or insert a card and then see a friendly prompt. It offers to charge the purchase in US dollars, which feels convenient and familiar. It’s also a habit that tells everyone you’re not used to local terminals.

Travel guides give the same advice. If a terminal offers to charge you in your home currency, say no and pay in Canadian dollars so your own card network does the conversion.[7] Another 2026 guide lists accepting dynamic currency conversion as a common mistake, and says to choose CAD at the terminal.[8]

It’s worth checking your receipt, too. The convenience can come with a less favourable rate than the one your own bank would apply.

Tipping on the Total After Tax

Tipping isn’t where Americans go wrong in the way you’d expect. The customs are close to home, since Canada’s tipping culture closely mirrors the United States, with servers relying on tips as a meaningful part of their income.[4] The slip is in what you calculate the tip on.

Prices in Canada are commonly shown before tax, and a restaurant guide suggests 15% for okay service, 18% for good and 20% for great, calculated on the subtotal before tax.[6] Tapping a suggested percentage on the final total quietly adds roughly two percentage points, so on a $100 meal in Ontario, 18% on the $113 total costs $20.34 instead of $18.[6] Quebec has its own rule, since 2025 payment terminals there must calculate suggested tips before tax.[6]

Staring at Road Signs and Weather Forecasts in Metric

Canada uses kilometres, grams and Celsius. Visitors who freeze at a speed limit sign or a forecast give themselves away quickly. Road signs show distances in metres and kilometres, and product weights are marked in grams or kilograms.[3]

It isn’t a recent change. Canada used the imperial system until a phased switch to metric began in the mid 1970s.[3] Earlier generations learned Fahrenheit for temperature and pounds and ounces for weight, but metric has become more prevalent as time has passed.[3]

Some older Canadians still talk about their height in feet and inches, or a baby’s weight in pounds. Everyday life, though, runs on metric. A quick conversion habit goes a long way.

Reaching for Pennies and Missing How Canadians Pay

Counting out exact change with pennies is an American reflex. Canada eliminated the penny in 2013,[9] so cash totals are rounded to the nearest five cents. Coins you’ll see instead include the one dollar loonie and the two dollar toonie.

Cards are the other half of the story. Tapping is the default for payments in Canada rather than the exception, and cash keeps shrinking every year.[10] Interac Flash launched in 2011, and by 2015 most Canadian bank issued debit cards could tap.[11] Interac then raised its contactless debit limits in September 2025, ending five years at $250 per tap.[11]

A visitor who inserts a card and waits for a prompt, or who digs for pocket change, can look a step behind the line. Tapping a phone or card is usually faster and perfectly normal.

Treating Canada as a Slightly Different Version of the US

The last giveaway is quieter and has to do with assumptions. A common one is getting the capital wrong. One list of traits Canadians notice about American tourists includes thinking the capital of Canada is Toronto.[3] It’s Ottawa, in Ontario.

Government and geography confuse people too. Canada’s head of state is the sovereign, currently King Charles III.[3] A Vancouver guide also warns about mixing up the three Vancouvers: Victoria is on Vancouver Island, and Vancouver, Washington is near Portland.[7]

Locals tend to forgive these slips, especially when the visitor is curious. Treating the country as its own place, with its own capital, politics and provinces, is what separates a guest from a tourist.
