Whitby is located in Durham Region in Southern Ontario, east of Ajax and west of Oshawa, on the north shore of Lake Ontario. It is about twenty kilometers (12 miles) east of the Toronto borough of Scarborough. The southern part of Whitby is predominantly urban and an economic hub; the northern part is more rural and includes the communities of Ashburn, Brooklin, Myrtle, and Myrtle Station.First Nations people were the original inhabitants of the area that would become Brooklin. In the 1820s European pioneers established a small settlement in the area. The settlement expanded in the 1840s when brothers John and Robert Campbell established a flour mill on Lynde Creek. Most of the buildings in the area of the walking tour are single-detached houses. It is a diverse collection of traditional architectural styles from the mid-nineteenth to mid-twentieth centuries. These diverse styles complement the landscape as the spaces between buildings offer glimpses of the creek, small parks, and treed open spaces.In 1819, John Scadding, clerk for Lieutenant-Governor John Graves Simcoe, was awarded a large tract of land now known as Port Whitby. Originally known as Port Windsor, the area encompassed the natural harbour in the south up to Victoria Street in the north. Soon after settlement, the harbour was used to ship local grain, lumber, and farm produce across Canada and the United States. Farmers transported their produce to Port Windsor using a plank toll road, now Brock Street, and the Port Whitby, Port Perry, and Lindsay Railway. From the 1840s to the 1870s, Windsor Harbour prospered, leading to a number of developments that modernized the harbour's infrastructure and surrounding industry. It was also during this time, in 1847, that Windsor Harbour was officially renamed Whitby Harbour. The bustling community of Port Whitby sprung up around the harbour with a number of houses, hotels, shops, and breweries supporting further development. Port Whitby, including the harbour, was one of three communities that formed the original Town of Whitby in 1855 along with Hamer's Corners and Perry's Corners.
