International House of Tea originated in Thunder Bay, Ontario as a fundraising project for local humanitarian organizations. The success of Humanitea created a demand for a permanent source of quality loose tea in Thunder Bay. International House of Tea opened its retail shop in November of 2006 on Fort William Road, sharing space with Orysi Aromatherapy and Solsbury Hill Wellness Centre. Having outgrown its first location in 2011, International House of Tea relocated to the Bay and Algoma Shopping District in June of that year.
International House of Tea has grown from a collection of a dozen teas to over one hundred teas, herbs and special blends. Many of Thunder Bay's finest restaurants and cafes serve iHOT teas, and the signature Thunder Bay Tea Blend is available in some local gift shops.
