Planning a Thousand Islands elopement means accounting for the water, the boats, and, uniquely, the international border that runs through the archipelago. Here is the practical sequence from first decision to the day.

The Border and the Legal Framework

The first decision is which side of the border your ceremony is on. For an Ontario ceremony, you need an Ontario marriage licence (about $145 from a municipal clerk, no waiting period). For a ceremony at Boldt Castle on the American side, New York State requirements apply, a separate process, and you and your guests need passports. This single decision shapes the entire legal plan, so make it first.

Finding Your Officiant

For an Ontario island elopement, a registered Ontario officiant who serves the Thousand Islands region is the standard choice, and many are experienced with boat-access and waterfront ceremonies. For a Boldt Castle ceremony, you need an officiant authorised in New York State. Confirm your officiant is comfortable with the specific location and its access, particularly for island and boat-based ceremonies.

Building the Day Around the Water

A Thousand Islands elopement day is built around boat access and the river. The boat charter, the island locations, and the dock logistics shape the timing, and the water adds a weather dependency. A common structure is a ceremony at an accessible shoreline or estate, then a boat excursion to the islands for portraits. Build generous buffer for the boat, the water, and the weather, and consider the long golden hours of a summer evening on the river.

The Details That Matter

The towns of the region, Gananoque, Kingston, and Brockville on the Ontario side, have florists and services accustomed to waterfront weddings, and a hand-tied bouquet of seasonal blooms photographs beautifully against the river and stone. For the celebratory dinner, the riverside towns and the historic inns offer everything from fine dining to cozy waterfront patios. A reservation overlooking the water is the natural conclusion to a river elopement.
