The Great Wall of Upper Canada played an important role in
Canadian history: The best known example of its impact
is:

Well, Brock's Retreat comes to mind. Rather than
fight it out at Queenston he led the Americans
out of the Niagara Peninsula to prepared
positions behind the Wall north of Burlington.
The Yanks bled themselves dry trying to hammer
their way past the Wall. We
know what happened after that...

Britain wound up with the northern areas of
the northern non-contigious areas of Massachusetts
and the Louisiana Territory north of the 45th Parallel. 
Of course, the Wall didn't help the British in Louisiana 
and most of Canada in 1853, when...

America, angry from losing the Mexican War due to
French and British intervention, invaded.  This
started the First Atlantic War.  America finally
lost when its southern States left due to its idea
of using negros in the Army.
The states that were left were....

themselves divided when the New England states,
traditionally closer to the Atlantic colonies
of Nova Scotia and New Brunswick, and dependant
on trade with Europe, cut off by the Royal Navy,
grew disgusted with the loss of business and
ceded from the runt-US and formed their own
nation, Atlantica.  The Atlantican navy
played a crucial role in 1883 when...

The country known as the Southron United States of
America (SUSA) declared war on the Spanish over an
incident in Cuba. The Atlantician navy decisively
defeated the SUSA Navy near Mobile. This didn't
prevent the revolt of slaves and the creation
of the free nation of Cuba. This
all had interesting consequences when in 1912...

The Republic of Grand Columbia, unified since the
1820s with the help of American refugee Aaron Burr,
invaded Mexico with Russian backing.  This prompted
Atlantica, the US, and the Ottoman Empire to...

.. foreclose on the Nicaragua Canal, which they had
jointly financed. An Ottoman fleet operating out of
the Hawai'ian Sultanate blockaded the west entrance,
and an Atlantican fleet the east.  This caused the
northern parts of Grand Colombia to secede, claim
control of the canal for itself, and form the
United States of Central America.  This new country,
needing an influential protector, granted a
Nicaragua Canal treaty zone to ...

...The Commonwealth of Canada, the former British and
French territories in North America west of Atlantica
to the Russian Pacific Panhandle that unified in 1848
and became independent in 1857 as a result of the "Red
River Scandal". The Scandal, or as it's more popularly
referred to in Britain as...

"Why did we hire that Idiot Palmerston?" Palmerston,
after being ridden out of England on a rail,
boarded a passenger ship headed for Japan.
He arrived in Tokyo in 1855, just in time for...

the Gaijin War, triggered by the seizure of Hanseatic
League property in Yokohama by the Korean-born shogun
Moritodo.  Palmerston, for some odd reason, convinced
both the League and the shogun that he could mediate
a peaceful agreement.  However, all three parties had
neglected the ambitious ambassador of the True United
States of America, Abraham Lincoln, who...

..., with the First Atlantic War going on, was looking for
allies with the US against Britain and Canada.  He incited
the shogun to seize British property throughout Japan.
Moritodo, more incited than Lincoln intended, promptly
seized all foreign property.  The Royal Navy responded
with raids upon the shogunate. One of these raids
led to the disaster of ...

Copenhagen, when a sabatoged British ammunition ship which
had somehow made it back to the Hanseatic port exploded
next to 13 ships stuffed to the gill with benzene.
Sinking over 40 British ships of the line and half again
as many Hanseatic ships, this disaster enabled...

... the Brazilian Empire a free hand in the Plata river basin.
With the British gone from the region, an army under the duke
of Caxias easily subdued Uruguay, adding the Cisplatine
province to the emperor Dom Pedro II's growing list of
dominions. The Argentine Confedaracy now began to feel
threatened and so when the princess Isabel became engaged
to the crown prince Manuel of Portugal, threatening to
reunite their thrones, they appealed from help from ...

The Morisco Republic, stretching from the Egyptian border to
the Atlantic. With a grudge against the Portuguese who had
expelled them from Iberia, they prepared their large army
and navy, though primitive, for war. Setting sail in
early 1855, they soon...

Caught the attention of Atlantica when they successfully
invaded Gibraltar and as far into Spain as Seville. Fearing
that their navy would be replaced as being the equal of
Britain's (recently deflated) fleet, Atlantica pulled
half of its ships from maintaining the SUSA Naval Blockade
(of 1883) and turned its attention to Morisco, beginning
the Trans-Atlantic War, which didn't end until...

1891, when the Morisco fleet broke the back of the Atlantican fleet
off the Azores. Atlantica ceded control of the Maderias and Canaries
to Morisco, while at the same time agreeing to allow Morisco naval
bases in Boston. The Morisco victory soon turned bitter, however,
when...

.. the resurgent Ottoman Turkish empire took Egypt from the Moriscos
in 1893.  The "Ottoman Renaissance" can largely be explained by the
other European and Mediterranean powers becoming bogged down in 
American politics, following the War of 1812.  With Egypt and the Suez
Canal under Ottoman control, Turkish fleets ranged all around Asia,
and even deep into the Pacific.  The Ottoman Sultan even dictated
peace terms at ...

Saigon, when the Khmer states surrendered their coastal regions
to the Ottoman fleet. Further Ottoman explorations planted colonies
in Australia and Java, colonies that proved largely successful
until 1912, when...

... the Russian khanate, fresh from wrestling Lithuania from the
Hanseatic league, turned its attention now to the game of colonization
that other large powers had embarked upon. Fresh from winning the 1912
election, and with hungry eyes on Ottoman Australia, the Khan used
his political power to ...

...make an alliance with the Boer Empire ,which had taken over
the British colonies in southern Africa and all of India.  With
a huge amount of gold and diamonds backing them, the Boers were
close to unbeatible.  But they and the Khan met their match
when....

they took on the French army at the battle of Fashoda. In a
titanic battle lasting for over a month, the Boer and Khanate
armies were utterly crushed, prompting ethnic revolts all
throughout both empires, something taken advantage of by...

... Kublai III the great, leader of the chinese imperial
khanate. wishing to avenge himself on the Russian khanate,
who'd formed the first modern democracy after breaking away
from the chinese khanate in the early 19th century, Kublai drove
his armies into Siberia, and took advantage of the power vacuum in
Boer Hindustan to seize the Hindustan province of Tibet. But a
new leader by the name of Mohandas Gandhi was appearing in 1921
in India, one who would ...

lead a crusade of blood and death against the khanate. Armies a
hundred thousand strong charged unafraid into the enemy machine
guns. Servants slit their employer's throats and soliders killed
their officers in the great Blood Night of July 1, 1921. Gandhi's
Great Horde left Hindustan and marched toward Khmer, long an
Atlantican client state and home of many a naval base and
coaling station. The Atlantican officer on the spot was Admiral...

Churchill, who had been exiled from Britain for his part in the
plot to .....

.... overthrow president James Joyce. Churchill had avoided prison
only due to his popularity, and Joyce's discredited public persona
after Churchill's revelations. But Churchill found now a way to
vindicate himself, when he defended Khmer with the aid of a new
weapon. This weapon, provided to them by the Brazilian Empire,
had been developed by a brilliant young immigrant from the
Hanseatic States, Albert Einstein, and was known as ...

... the Fuel-Air Demolition Bomb.  Einstein was a chemical engineer in
the service of Petroleo Nacional do Brasil, and developed all manner of
plastics and petroleum-based innovations.  Unlike "the Bomb", most of
these inventions were life-saving.  The first artificial heart, which
Einstein helped construct, saved the life of...

Crown Prince Pedro, heir to the United Empire of Brazil and Portugal, in
1905. It was due largely to Pedro's personal charm that Portugal's ancient
enmity with the Morisco Republic was finally brought to an end, and an alliance
formed between the two nations in 1914 to face the growing power of the Ottoman
Empire.  When Pedro succeded his father Manuel as King-Emperor in 1923,
his first act was to provide the Russian Khan with...

a "heart attack". He'd been about to hand the khanate over to the Ottomans,
which you just can't allow. The new Khan was far more inclined to listen
to the Portuguese king, when he provided...

... military support in retaking Siberia from the Chinese Khanate. This was
made easier by Churchill's dramatic victory which threw all of East Asia
into revolutionary upheavel. Of course, Gandhi himself managed to escape the
Khmer massacre, where he fled to ...

The Holy State of Tibet. Taking advantage of the turmoil between the
Khanates to the north, Tibet wrested independence from the Chinese Imperial
Khanate with a series of terrorist immolations. Tibetan monks boarded
crowded trains and entered government offices in the Chinese Khanate and
then ignited themselves. Without Gandhi the Bloody at the helm, Hindustan
lost...

Much of their northern territory to Tibet. They were further left open to a
series of lightening raids from US naval vessels marking vengeance for the
massacre of American civilians. One of these vessels, the USS Arizona,
commanded by Captain Ernest King, while cruising off Ethiopia, stumbled upon...

A Hanseatic convoy, bound for Madagascar, from the Ethiop-Hanseatic
shared-port city of Mogadishu. Captain King's February 11th, 1927 attempt to
raid the convoy proved fool-hardy, for the convoy easily grounded the TUSA
ship in the straits of the Amirante Isles. While this event is insignifigant
in itself, the absense of the TUSA vessel at the Battle of Miami turned the
tables on the would-be invasion of the SUSA in October of 1927. The TUSA
naval force barely escaped Miami when the SUSA forces...

(Remember, there are three USAs - the True United States of America, the
Southern United States of America, and the United States of Central America
[OTL-Nicaragua].)

.... arrived with reinforcements from the Hanseatic navy. This outraged the
Brazilians, who through their "Manuel doctrine", claimed the Americas
as their exclusive zone of influence. Hanseatic influence on these so-called
"apple republics" (because large apple companies controlled their economies),
threatened this, and not wanting to appear weak, emperor dom Pedro 
retaliated by ...

... declaring sanctions and presenting an ultimatum to the Southron USA and 
the Hanseatic League.  This gained the attention of the League of 
Non-Aligned Nations, an alliance of minor powers which was founded under 
Norwegian leadership in 1914, shortly after Norway gained independence from 
Sweden.  To forestall a Brazilian invasion of Florida, the League arranged 
to garrison Miami with peace-keeping troops from ...

... Canada.

And that is how the Great Wall of Upper Canada played an important role
in Canadian history.
