The One State That Doesn't Touch Canada
Here's a geography question that trips up more people than you'd expect: which of the following states does not border Canada? It's the kind of thing that seems obvious once you know the answer, but good luck getting most folks to name all the states that do share a border with our northern neighbor.
This is the bit that actually matters in practice Small thing, real impact..
I've watched people confidently list states that are nowhere near Canada, and I've seen others stare at a map for five minutes trying to remember whether Minnesota really touches the border. The truth is, there are only a handful of states that don't border Canada — and the answer to this specific question is surprisingly straightforward once you know what to look for.
So whether you're cramming for a trivia night, helping a kid with homework, or just curious about North American geography, here's everything you need to know about which states border Canada — and which one stands out by not doing so.
What Does It Mean to Border Canada?
Let's start with the basics. When we say a state "borders Canada," we mean it shares a land boundary with one of Canada's provinces or territories. Now, the United States and Canada share the longest international border in the world — over 5,500 miles of it. That's longer than the borders of most countries.
The States That Do Border Canada
There are exactly 14 U.S. states that share a land border with Canada:
Maine — borders New Brunswick and Quebec
New Hampshire — borders Quebec
Vermont — borders Quebec
Massachusetts — technically borders Quebec at the very tip of its northwest corner (yes, really)
New York — borders Ontario and Quebec
Michigan — borders Ontario across the Great Lakes
Ohio — borders Ontario across Lake Erie
Pennsylvania — borders Ontario across Lake Erie
New Jersey — borders Ontario across the water (this one's debatable depending on how you define "border")
Wisconsin — borders Ontario across Lake Superior
Minnesota — borders Ontario and Manitoba
North Dakota — borders Manitoba and Saskatchewan
Montana — borders Saskatchewan, Alberta, and British Columbia
Washington — borders British Columbia
That's a lot of states, and if you're like most people, you probably forgot about a few of them. Ohio? Massachusetts? Those aren't the first states that come to mind when you think "Canada border," but they technically do touch it.

The Geography Reality Check
Here's what makes this tricky: the Canada-U.S. Also, it follows rivers, lakes, and survey lines. Some states touch Canada only across a lake or river. So border isn't just a straight line running east to west. Others have tiny corner intersections that most people never knew existed.
Not obvious, but once you see it — you'll see it everywhere Small thing, real impact..
Massachusetts, for example, has a border with Quebec that's less than a mile long — it's at the very tip of the state where the Connecticut River meets the Canadian border. Most Massachusetts residents have probably never driven to that exact spot.
Why This Question Trips People Up
The confusion around which states border Canada comes down to a few factors. Consider this: first, the border is incredibly long and winding. Second, many of the states that do border Canada are in the northern part of the country — but not all of them. And third, people tend to think of the most obvious cases (like Alaska, Washington, Montana) and forget about the smaller touches.
The Psychological Shortcut
Most people use a mental shortcut: they think of the big, obvious border states and assume that's the complete list. When someone asks "which states border Canada," they picture the map in their head — the northern tier of states, plus Alaska — and stop there That alone is useful..
But the reality is more nuanced. Ohio borders Ontario across Lake Erie. The border dips south in places, follows waterways, and creates some unexpected connections. Pennsylvania does too. New Jersey technically has a maritime border with Ontario Practical, not theoretical..
The Alaska Factor
Alaska is the wildcard here. It borders both British Columbia and the Yukon Territory, but it's separated from the rest of the U.S. Think about it: by Canada. This makes it unique — it's the only state that borders Canada but isn't connected to the contiguous United States It's one of those things that adds up..
How the Border Actually Works
The Canada-U.S. border wasn't drawn overnight. It evolved over centuries through treaties, negotiations, and sometimes just practical decisions about where the line should go.
Historical Boundaries
The original 13 colonies all had claims or actual territory that touched what is now Canada — but those were colonial boundaries, not modern state lines. After the American Revolution, the new nation's relationship with British North America (later Canada) was complicated.
The border as we know it today was largely established by the Webster-Ashburton Treaty of 1842 and the Alaska Purchase in 1867. These agreements settled many disputes and created the relatively peaceful relationship between the two nations that continues today.
Water Borders vs. Land Borders
A standout biggest sources of confusion is the distinction between land borders and water borders. Many states touch Canada only across a lake or river:
- Michigan — borders Ontario across the Detroit River and several Great Lakes
- Ohio — borders Ontario across Lake Erie
- Pennsylvania — also borders Ontario across Lake Erie
- New York — borders Ontario across Lake Ontario and the St. Lawrence River
These water borders are legally recognized international boundaries, but they don't look like traditional land borders on a map.
Common Mistakes People Make
Even geography enthusiasts get this wrong sometimes. Here are the most common errors:
Overcounting Border States
People often include states that are near Canada but don't actually touch it. Idaho is a frequent offender — it's close to British Columbia but doesn't share a border. Wyoming and Colorado are also commonly mistaken for border states No workaround needed..
Undercounting Border States
Just as common is forgetting some of the less obvious border states. Massachusetts catches people off guard. So does New Hampshire, which many assume is too small to have an international border And it works..
Confusing Proximity with Borders
West Virginia is close to Canada (relatively speaking), but it doesn't share a border. Neither does Maryland, despite being on the East Coast. Distance doesn't equal adjacency.
The Answer to Your Question
So, which of the following states does not border Canada?
If you're working from a specific list, the answer depends on what states are included in that list. But here's the key insight: among the states that people most commonly assume border Canada, Idaho is the one that doesn't Nothing fancy..
Idaho is often grouped with the Pacific Northwest states that border Canada, but it actually stops short. The Idaho panhandle comes close to British Columbia, but there's no direct border. Washington and Montana both border Canada, but Idaho sits between them geographically without touching the border itself Easy to understand, harder to ignore. Nothing fancy..
Other states that don't border Canada but are commonly confused: Wyoming, Colorado, Nebraska, Kansas, and Oklahoma — all landlocked states that are nowhere near the Canadian border.
Practical Tips for Remembering
Here's what actually works when it comes to memorizing the Canada-bordering states:
Use the Map Method
Look at a map of North America and trace the border with your finger. Which means start in the east at Maine and follow it west through New Hampshire, Vermont, New York, and so on. You'll naturally pick up the rhythm of which states touch the line Simple, but easy to overlook..
Group by Region
Think of the border in sections:
- Northeast: Maine, New Hampshire, Vermont, New York
- Great Lakes: Michigan, Ohio, Pennsylvania, Wisconsin, Minnesota
- Northern Plains: North Dakota, Montana
- Northwest: Washington, Alaska
This makes it easier to remember which regions have border states and which don't.
Remember the Exceptions
The states that don't border Canada but might seem like they should: Idaho, Wyoming, Colorado, and the entire southern tier of states. If a state is landlocked and south of the Great Lakes, it almost certainly doesn't border Canada Most people skip this — try not to..
FAQ
Which U.S. state has the longest border with Canada?
Alaska has the longest international border
with Canada, stretching across the frozen wilderness of the Yukon, British Columbia, and Alaska's southeastern panhandle. For the contiguous United States, Montana holds the longest border, running roughly 545 miles along the northern edge of the state.
Which states have the shortest border with Canada?
Several states share only a sliver of border with Canada. Pennsylvania and Ohio each touch the international boundary for just a few miles, making them among the shortest border encounters in the country. Even less well-known is that Vermont has a relatively modest stretch of border compared to New York or Michigan, despite its northern location That alone is useful..
Does every northern state border Canada?
No. This is one of the most persistent geographic misconceptions. States like Idaho, Wyoming, Colorado, Utah, Nevada, and Arizona are all located in the northern half of the country (or, in Arizona's case, the southwestern quarter) but share no border with Canada. Latitude alone does not determine adjacency — a state must physically touch the 49th parallel or the Alaska boundary to qualify That's the whole idea..
How many U.S. states border Canada in total?
Thirteen states share a border with Canada: Maine, New Hampshire, Vermont, New York, Pennsylvania, Ohio, Michigan, Wisconsin, Minnesota, North Dakota, Montana, Idaho (no — Idaho does not), Washington, and Alaska. Correcting that, the total is thirteen: Maine, New Hampshire, Vermont, New York, Pennsylvania, Ohio, Michigan, Wisconsin, Minnesota, North Dakota, Montana, Washington, and Alaska.
Final Thought
Understanding which states border Canada is more than just a trivia exercise. And s. That's why the U. On the flip side, -Canada border is the longest international boundary in the world between two nations — stretching over 5,500 miles — and it touches a surprisingly large portion of the American landscape. It has real-world implications for trade, travel, immigration policy, and national security. From the fishing villages of Maine to the rainforests of Alaska, this border shapes the economies, cultures, and daily lives of millions of people on both sides.
Worth pausing on this one.
The next time someone asks you which states border Canada, don't just recite a list. Because of that, trace the border in your mind, group the states by region, and remember the common traps — Idaho's deceptive proximity, Wyoming's landlocked isolation, and the easy assumption that every northern state makes the cut. Geography is full of these nuances, and appreciating them is the first step toward a deeper understanding of the map beneath our feet And it works..
