Zavikon Island refers to either the larger or the pair of islands in the Thousand Islands archipelago on the St. Lawrence River between New York and Ontario, two kilometres (1ü miles) southeast of Rockport, Ontario and approximately north of the international boundary. Zavikon Island is located in Canadian territory and is part of the township of Leeds and the Thousand Islands in the United Counties of Leeds and Grenville.
In April 1975, Donald Rickerd bought the two islands. A bridge connects the larger island to the smaller island. A Canadian flag hangs on the bridge near the larger island, and an American flag adorns the other side. A Hungarian flag hangs on the middle of the bridge in honour of the Hungarian heritage of his wife, Julie Rékai Rickerd. In 1988, "Zavikon Island" was established as its official name.
The smaller and more southeasterly of the pair of islands is sometimes called "Little Zavikon Island." It has a US-Canada Boundary Commission reference monument, from which surveying measurements are used to calculate the international border line turning point at this section of the river. In this case, the international border's turning point is approximately 140 metres (460 ft) southeast of the southern tip of Little Zavikon Island as shown on the largest scale USGS map of the area.
A popular misconception is that the larger island is in Canada while "Little Zavikon Island" is in the United States, and that the footbridge between them is the shortest international bridge in the world. As demonstrated by Canada's official topographic map of the area (see image), both Zavikon islands are wholly within Canada.
The Zavikon estate was established at the beginning of the 1900s as a privately-owned country retreat located entirely within Canada among the islands attached to the geographic Township of Escott, Ontario. Since its formation, the estate has comprised three officially recognized islands:
Island 103B is visible in some aerial photographs and was used as the base for the outer section of a large deck extending from Aspasia Island. Island 103A and Island 103B are the designations used on the official land plan in lieu of lot numbers or official names, such as Aspasia Island.
Following a June 1918 change in the ownership of the estate, a second title, Zavikon Island, was used for the aggregate property by its new owners. A short silent film, Zavikon, illustrating the estate circa 1929, is posted online.
The three islands of the Zavikon estate had once been part of the lands of the indigenous Mississaugas of Alnwick. In 1856, this group of Mississauga Ojibweg surrendered their islands in the Thousand Islands region of the St. Lawrence River to the Crown. The agreement required that the funds from the sale of the surrendered islands be invested and the interest paid annually to the Alnwick Mississaugas, who are now known as the Alderville First Nation.
An official survey of the Canadian Thousand Islands between Gananoque and Brockville was done in 1873 at the direction of Canada's Secretary of State for the Provinces (who was also Superintendent General of Indian Affairs) and published in March 1874. A copy was deposited as Plan 120 in Ontario's Land Registry Office for Leeds County (Leeds LRO 28) in December 1882. Additions were made to the official plan in April 1893 as per a new survey. These additions included the previously absent Island 103B and a label for previously unnumbered Island 103A.
Ownership of each of the three islands was transferred individually by the Department of Indian Affairs via Crown Land Patents in 1894, 1897, and 1901, respectively. In accordance with the 1856 surrender, the patents stated that the islands were sold "in order that the proceeds may be applied to the benefit, support and advantage" of the Mississaugas of Alnwick. The documents cited the official survey plans of 1874 and 1893 as held in the Department rather than the Plan 120 held in the local Land Registry Office.
The first private owners of the respective islands were as follows:
Emilie D. Robb (née Taylor, also known as "Mrs. Alexander Robb") purchased Aspasia Island and Island 103A from Powell and Hurdman on October 16 and 12, 1901, respectively. Her country house was completed in August 1902 and the estate was given the name of Zavikon.
Zavikon was frequently misspelled in early newspaper reports, e.g., Zavicon, Zabikon, Zaoikon. The entries for Emilie and Alexander Robb in the annual Brooklyn Blue Book and Long Island Society Register of 1910âÂÂ1922 spelled the title as Zavikön, with two dots (umlaut) above the "o". This spelling was also used in the Robbs' entries in the 1910âÂÂ1915 annual summer issues of <em>Social Register</em>: "Robb Mr & Mrs Alex (Emily D Taylor). <strong>'</strong>Zavik<strong>ö</strong>n<strong>'</strong> Alexandria Bay NY" [bold emphasis added].
The application of the name Zavikon to the entire three-island estate is demonstrated by the June 1918 deed that transferred its ownership from Emilie D. Robb to Andrew McLean of the City of Passaic, New Jersey. This deed described the property as follows:
At some point following this transaction, the new owner adopted the title of Zavikon Island for the estate. In June 1931, when the executors of the will of Andrew McLean sold the estate to Philip A. Castner of Philadelphia, Pennsylvania, the above text was repeated nearly verbatim in the applicable deeds with the substitution of Zavikon Island for Zavikon.
In subsequent transfers of ownership, the text quoted above â with the title Zavikon Island for the three-island estate â was repeated in the respective deeds:
On February 12, 1988, Aspasia Island was officially renamed Zavikon Island. As of March 23, 2026, no transactions for the estate have been registered at the Land Registry Office since May 1975.
