If You’re In Windsor, Ontario, Canada & Want To Get To Detroit You Have To Head North Rather Than South – Brilliant Maps

If You're In Windsor, Ontario, Canada & Want To Get To Detroit You Have To Drive North Rather Than South

The
map
above
shows
an
unintuitive
geographical
fact.

If
you’re
in
Windsor,
Ontario,
Canada
and
want
to
visit
Detroit
on
the
US
side
of
the
border,
you
head
north
rather
than
south
as
you’d
expect.

Why?

The

Detroit
River

has
long
served
as
a
natural
dividing
line,
and
its
role
in
marking
the
U.S.–Canada
border
is
rooted
in
centuries
of
history
and
international
treaties.

Here’s
a
closer
look
at
how
this
unique
border
came
to
be:


  1. Natural
    Features
    as
    Boundaries:

    When
    European
    powers
    and
    later
    the
    emerging
    nations
    were
    carving
    up
    territories
    in
    North
    America,
    natural
    landmarks
    like
    rivers
    were
    often
    used
    to
    define
    borders
    because
    they
    were
    clear,
    unchanging
    features
    on
    the
    landscape.
    The
    Detroit
    River,
    flowing
    between
    what
    is
    now
    Windsor
    and
    Detroit,
    naturally
    lent
    itself
    to
    this
    role.

  2. Early
    Treaties
    and
    Agreements:


    • Post-Revolutionary
      War
      Arrangements:

      After
      the

      American
      Revolutionary
      War
      ,
      boundaries
      between

      British
      North
      America

      (which
      would
      become
      Canada)
      and
      the
      newly
      independent
      United
      States
      were
      hotly
      contested.
      Although
      the
      Treaty
      of
      Paris
      in
      1783
      set
      some
      initial
      guidelines,
      it
      was
      not
      until
      later
      that
      the
      Great
      Lakes
      region
      received
      more
      precise
      attention.

    • The
      Jay
      Treaty
      (1794):

      This
      agreement
      between

      the
      U.S.
      and
      Great
      Britain
      helped
      to
      stabilize
      relations
      and
      clarify
      some
      of
      the
      disputed
      boundaries
      in
      the
      Great
      Lakes
      region,
      including
      areas
      around
      the
      Detroit
      River.

    • Subsequent
      Treaties
      and
      Agreements:

      Later,
      treaties
      such
      as
      the

      Treaty
      of
      Ghent

      (1814),
      which
      ended
      the
      War
      of
      1812,
      and
      the

      Rush-Bagot
      Agreement

      (1817),
      which
      limited
      military
      forces
      on
      the
      Great
      Lakes,
      reinforced
      the
      use
      of
      natural
      boundaries
      like
      the
      Detroit
      River
      to
      demarcate
      national
      territories.

  3. Surveys
    and
    Local
    Decisions:

    Over
    time,
    detailed
    surveys
    were
    conducted
    to
    pinpoint
    the
    exact
    line
    running
    down
    the
    middle
    of
    the
    river.
    These
    surveys
    confirmed
    that
    Windsor
    is
    on
    the
    southern
    bank
    (designated
    as
    Canadian
    territory)
    while
    Detroit
    lies
    on
    the
    northern
    bank
    (within
    U.S.
    territory).
    Even
    though
    this
    might
    seem
    counterintuitive—given
    the
    general
    notion
    that
    Canada
    lies
    “up
    north”—it’s
    the
    result
    of
    following
    the
    river’s
    course
    rather
    than
    strict
    latitude
    lines.

  4. Modern
    Implications:

    Today,
    this
    historical
    arrangement
    means
    that
    if
    you’re
    in
    Windsor,
    Ontario,
    and
    you
    drive
    north
    across
    the
    Detroit
    River,
    you’re
    crossing
    an
    international
    border
    into
    Detroit,
    Michigan.
    The
    decision
    to
    use
    the
    river
    as
    the
    dividing
    line
    has
    persisted,
    reinforcing
    how
    historical
    treaties
    and
    natural
    geography
    can
    create
    quirky,
    memorable
    borders.

Have
you
ever
driven
across
the
ambassador
bridge?
