My Point from above is that England doesnt even have 10K Troops in North America in 1861.  6 Months after the start of Hostilities the Union has recruited 500,000 Troops and armed them.

If the British Regulars lets say 25,000 of them are some how delivered to Canada in the Spring of 1862 once the St. Lawrence unfreezes and then are moved overland to the Detroit Area their is no way to hide this move from the U.S.   

The US response is to station 25,000 Men in fortress along the Detroit River and the British Regulars will learn what happens when you march men into Cannon Fire and Aimed Rifled Musket Fire while the defenders have even a bit of cover ???

Its an interesting theory but the British will have to actively intervene at Sea to break the Blockade and it will be bloody and Expensive.   Historically the US durring the War of 1812 captured something like 1200 British Merchants using letters or marque.   This would have been devestating to both the Union and British Economy.  By the Time the British Intervene New Orleans has Fallen and the British arent going to try to take it back the Hard way.

That is MY point as well.
The Union didn't have 500,000 troops, either.
They recruited and trained them on the fly.
There is nothing form stopping the British from doing this in Canada either- unless this is some strange parallel universe where Canadians can't fight.
So 'ere's to you, Fuzzy-Wuzzy, at your 'ome in old Baghdad;
You're a pore benighted 'eathen but a first-class fightin' man;

We'll come an' 'ave a romp with you whenever you're inclined.

The main issue would be that there are only around 3 million Canadians in the 1860s (half the non-slave population of the CSA) and probably nothing in terms of a domestic military armaments industry in place. The UK could do it, but it might very well set back Canada for generations as it did to the CSA in our own timeline.

Apart from the timeline, how about the general look of of the capital ship OOBs for the great powers and the Austro-Hungarian battleship and large heavy cruiser?

*Evil Grin*

Yes Canada simply doesnt have the population is an actual haven for Escaped Slaves and would probably actively oppose a war with the Union on its Borders.   

QuoteBy the end of 1861 700,000 soldiers were drilling in Union camps. The first wave in spring was called up for only 90 days, then went home or reenlisted. Later waves enlisted for three years. They spent their time drilling. The combat in the first year, though strategically important, involved relatively small forces and few casualties. Sickness was a much more serious cause of hospitalization or death. In the first few months men wore low quality uniforms made of "shoddy" but by fall sturdy wool uniforms--in blue--were standard. The nation's factories were converted to produce the rifles, cannon, wagons, tents, telegraph sets and the myriad other special items the army needed. While business had been slow or depressed in spring 1861 because of war fears and Southern boycotts, by fall business was hiring again, offering young men jobs that were an alternative way to help win the war. Nonpartisanship was the rule in the first year, but by summer 1862 many Democrats had stopped supporting the war effort and volunteering fell off sharply in their strongholds. The calls for more and more soldiers continued, so states and localities responded by offering cash bonuses. By 1863 a draft law was in effect, but few men actually were drafted and served, since it was designed to get them to volunteer or hire a substitute. Others hid away or left the country. With the Emancipation proclamation taking effect in January 1863, localities could meet their draft quota by sponsoring regiments of ex-slaves organized in the South.[14]

As you can see following the South Seizing Fort Sumter the Union quickly had 700K Troops drilling the Idea that Canada was going to put roughly 1/4 to 1/3 of its population under arms is funny and the British Regualr Army has its own Garrison duties in India and the Empire to perform.

On land the Union after 1862 when the Northern Industry started cranking out guns, standard uniforms, tents everything a modern army needs is simply a monster to tackle.  At Sea now there the British have their edge.

Now the Orders of Battle look interesting.
