Later, in the nineteenth century and continuing to the present, mining became an important economic activity. Early businesses in Havelock included a post office, store, bakery, a blacksmith and a millinery and were located south of the current village on high ground at the intersection of County Road 30 and Old Norwood Road. In 1881, the Canadian Pacific Railway surveyed a right-of-way through the area north of Havelock and a year later laid rails and surveyed and filled the swampy land to make room for a larger village.
