I would have to say that the war was a draw. No American aims were accomplished (except that our sailor's rights were observed, our industry began to build up due to the blockade, and there was a new wave of nationalism that resulted in the "Era of Good Feelings" during which many canals and roads were built adding to the infrastructure of our young country)
and no British aims were accomplished, if they really had any in the first place other than simply ending the war. To me, the war was a draw, but we "Yanks" took it as a victory, and actually enjoyed the afore mentioned fruits of that victory (unfortunately, munching on Canadian bacon was not in the cards for us. Too bad. You know, if you guys want to be annexed, it's not too late. Texas did it.

)
I suspect their main aim was to kick you guys out of Canada
I googled this book, it may be of interest to those into this era:
Don't Give Up the Ship!
Myths of the War of 1812
Donald R. Hickey
Foreword by Donald E. Graves
Clearing the fog from the war of 1812
No longer willing to accept naval blockades, the impressment of American seamen, and seizures of American ships and cargos, the United States declared war on Great Britain. The aim was to frighten Britain into concessions and, if that failed, to bring the war to a swift conclusion with a quick strike at Canada. But the British refused to cave in to American demands, the Canadian campaign ended in disaster, and the U.S. government had to flee Washington, D.C., when it was invaded and burned by a British army.
By all objective measures, the War of 1812 was a debacle for the young republic, and yet it was celebrated as a great military triumph. The American people believed they had won the war and expelled the invader. Oliver H. Perry became a military hero, Francis Scott Key composed what became the national anthem and commenced a national reverence for the flag, and the U.S.S. Constitution, "Old Ironsides," became a symbol of American invincibility. Every aspect of the war, from its causes to its conclusion, was refashioned to heighten the successes, obscure the mistakes, and blur embarrassing distinctions, long before there were mass media or public relations officers in the Pentagon.
In this entertaining and meticulously researched book by America's leading authority on the War of 1812, Donald R. Hickey dispels the many misconceptions that distort our view of America's second war with Great Britain. Embracing military, naval, political, economic, and diplomatic analyses, Hickey looks carefully at how the war was fought between 1812 and 1815, and how it was remembered thereafter. Was the original declaration of war a bluff? What were the real roles of Canadian traitor Joseph Willcocks, Mohawk leader John Norton, pirate Jean Laffite, and American naval hero Lucy Baker? Who killed the Shawnee chief Tecumseh and who shot the British general Isaac Brock? Who actually won the war, and what is its lasting legacy? Hickey peels away fantasies and embellishments to explore why certain myths gained currency and how they contributed to the way that the United States and Canada view themselves and each other.
