In 2012, members of the LRNA voiced concern about the deterioration of the Rosseau Shoal Lighthouse.
The LRNA contacted the Canadian Coast Guard and learned that the lighthouse had been declared surplus by the Federal Government and would no longer be maintained. The LRNA also learned that if the lighthouse was designated historical, the local municipality could apply to assume ownership of the lighthouse including responsibility for its restoration and ongoing maintenance.
To support this initiative the Township of Seguin required a commitment of $20,000. The LRNA generously welcomed the challenge and began its successful fund-raising campaign. By 2014, the Township had succeeded in assuming ownership and restoration work was completed. The township is responsible for all maintenance of this historic landmark
This iconic, historical lighthouse, first constructed in 1890, has now been fully restored for the continuing enjoyment by residents and visitors to North Lake Rosseau. A plaque commemorating the history of the Rosseau Shoal Lighthouse can be found hanging in the Rosseau waterfront park.
