question:
Question: Of the two provinces to the east of Montreal, which has the largest land area? Passage:As a British colony, and with immigration no longer limited to members of the Roman Catholic religion, the city began to grow from British immigration. American Revolutionists under General Richard Montgomery briefly captured the city during the 1775 invasion of Canada but left when it became obvious they could not hold Canada. Often having suffered loss of property and personal attacks during hostilities, thousands of English-speaking Loyalists migrated to Canada from the American colonies during and after the American Revolution. In 1782, John Molson estimated the population of the city at 6,000. The government provided most with land, settling them in what became Upper Canada (Ontario) to the west, as well as Nova Scotia and New Brunswick to the east. The first Protestant church in Montreal was St. Gabriel's, established by a Presbyterian missionary in 1792. With 19th-century immigration, more and more English-speaking merchants and residents continued to arrive in what had by then become known as Montreal. Soon the main language of commerce in the city was English. The golden era of fur trading began in the city with the advent of the locally owned North West Company, the main rival to the primarily British Hudson's Bay Company. The first machine shop in Montreal, owned by one George Platt, was in operation before 1809. The census of 1821 numbered 18,767 residents.
