Question: What town is considered to be the start of colonization that included the Americas, as well as Upper Canada and Lower Canada?

Context paragraphs:
The Canadas: The Canadas is the collective name for Upper Canada and Lower Canada, two British historical colonies in present-day Canada.  They were both created by the Constitutional Act of 1791 and abolished in 1841 with the union of Upper and Lower Canada.

Parliament of Lower Canada: The Parliament of Lower Canada was the legislature for Lower Canada.  It was created when the old Province of Quebec was split into Lower Canada and Upper Canada in 1791.

Parliament of the Province of Canada: The Parliament of the Province of Canada was the legislature for the United Province of Canada, made up the two regions of Canada West (formerly Upper Canada, later Ontario) and Canada East (formerly Lower Canada, later Quebec).  It was established by the Act of Union 1840 and replaced the two separate legislatures of Upper and Lower Canada, following the Rebellions of 1837 and Lord Durham's 1839 Report to the British Government recommending a legislative union between the two colonies.

Osgoode Hall Law School: Osgoode Hall Law School is a law school in Toronto, Ontario.  While it was founded by the Law Society of Upper Canada, it now serves as the faculty of law of York University.  It is named after William Osgoode, an Oxford University graduate and barrister of Lincoln's Inn who was the first to serve as the Chief Justice of Upper Canada, and then later Lower Canada.  Although it can trace its origins to the 1820s, Osgoode Hall Law School was officially established on-site in the Osgoode Hall building, which still houses the Law Society of Upper Canada and the Court of Appeal for Ontario, on Queen Street West in 1889.  Following a provincial decision that every law school be affiliated with a university, Osgoode signed an "agreement of affiliation" with York University in 1965 while still operating out of Osgoode Hall.  Osgoode has been housed at York University's Keele Campus since 1969 (see section below).

Nathan Bangs: Nathan Bangs (May 2, 1778 – May 3, 1862) was an American Christian theologian in the Methodist tradition and influential leader in the Methodist Episcopal Church prior to the 1860s.  Born in Stratford, Connecticut, he received a limited education, taught school, and in 1799 went to Upper Canada in search of work as either a teacher or a land-surveyor.  He was converted to Methodism in 1800 and worked for eight years as an itinerant preacher in the wilderness of the Canadian provinces, serving communities in the areas of Kingston, York, London, Niagara, and Montreal.  Of particular note is his responsibility for organizing the first camp meeting in Upper Canada in the fall of 1805.  That same year, he married Canadian Mary Bolton and, after a brief stint in Lower Canada, was transferred back to the United States in 1808, first in Albany and then New York in 1810.  In 1812, Bangs was made the Presiding Elder of the Lower Canada District, also riding the Montreal Circuit.  Bangs was esteemed within the church, and could have requested and received a much more pleasant assignment.  However, with war brewing between Britain and America, few riders would volunteer for assignment to Canada, and Bishop Asbury would not assign non-volunteers.  Bangs volunteered to be assigned to Canada, as there was a desperate need for volunteers.  The war prevented Bangs from reaching his assignment, however, and Bangs instead was made Presiding Elder of the Croton Circuit in Delaware, while Thomas Burch went to the Montreal Circuit instead.  In subsequent years, he took a prominent part in the councils of the church.

Parliament of Upper Canada: The Parliament of Upper Canada was the legislature for Upper Canada.  It was created when the old Province of Quebec was split into Upper Canada and Lower Canada in 1791.

Upper Canada Rebellion: The Upper Canada Rebellion was an insurrection against the oligarchic government of the British colony of Upper Canada (present day Ontario) in December 1837.  While public grievances had existed for years, it was the rebellion in Lower Canada (present day Quebec) that emboldened rebels in Upper Canada to openly revolt soon after.  The Upper Canada Rebellion was largely defeated shortly after it began, although resistance lingered until 1838 (and became more violent) - mainly through the support of the Hunters' Lodges, a secret anti-British, US-based militia that emerged around the Great Lakes.  They launched the Patriot War in 1838-39.  The rebellion led directly to Lord Durham's Report on the Affairs of British North America and to "The British North America Act, 1840" which partially reformed the British provinces into a unitary system.

Lower Canada Rebellion: The Lower Canada Rebellion (French: "La rébellion du Bas-Canada"), commonly referred to as the Patriots' War (French: "la Guerre des patriotes") by Quebecers, is the name given to the armed conflict in 1837–38 between the rebels of Lower Canada (now Quebec) and the British colonial power of that province.  Together with the simultaneous Upper Canada Rebellion in the neighbouring colony of Upper Canada (now Ontario), it formed the Rebellions of 1837.  The rebellion of Lower Canada continued in 1838 and in Quebec is often called "Les rébellions de 1837–38."

John Elmsley: John Elmsley (1762 – April 29, 1805) was Chief Justice of Upper Canada and afterwards Lower Canada.  In both the Canadas he served as President of the Executive Council and Speaker of the Legislative Council.  During the Hunter administration, he was the most powerful man in Upper Canada.  In Lower Canada, from 1802 until his death he was second only in rank to the Lieutenant Governor.

British colonization of the Americas: The British colonization of the Americas (including colonization by both the English and the Scots) began in 1607 in Jamestown, Virginia and reached its peak when colonies had been established throughout the Americas.  The British were among the most important colonizers of the Americas, and their American empire came to rival the Spanish American colonies in military and economic might.
