I have another look at one of the boat bays at the Ottawa Rowing Club today. The club is the oldest of its kind in the country, and the second largest, with over a thousand members. There are other rowing and boating clubs here in Ottawa and Gatineau, including downstream in the New Edinburgh-Rockcliffe area, and along the Rideau River at Mooney's Bay.
Across the river in Gatineau there's a harbour along the shore, and the greenspace you see is Jacques Cartier Park.
The multipurpose room on the second floor of the first building was open. There were various boats up in the rafters, as well as plaques, and a look down at boats on the lawn between this and the second boathouse. One of the staff on hand mentioned the place was being prepared for a wedding reception that evening. It's quite a lovely spot for such a purpose, with a great view.
