I did a guest post yesterday at Molly Jo's blog Frankly My Dear about the Canadian Tulip Festival's origins and photographing the entire event, complete with photographs from previous years. Go on over to that link, check it out, and leave a reply.
Many homes in Ottawa will have tulips this time of year, including these gardens in the Centretown area last week.
There were also tulips to be found in Dundonald Park.
These last ones can be found in the flowerbeds at the Sunnyside branch of the Ottawa Public Library. Those in the first two shots would be of the Canada 150 variety.
