I'm leaving for Ottawa tomorrow and will be there for about 6 days. The weather forecast's looking not bad at all for Ottawa, save for a couple of cool days.
Last time I was in Ottawa was ten years ago in mid to late May, and the weather was so horribly cold and cloudy that tulips weren't blooming in time for the Tulip Festival. In fact, it actually snowed in Ottawa at one point while I was there, but left nothing on the ground. That was the kind of weather I'd had expected for May in Calgary or Edmonton, but not Ottawa! (note that Ottawa is about as far north as Portland, OR, and southern Montana or just above 45°N).
Wow, you weren't lucky... since 2000, Ottawa has had only 5 "trace of snow" days: May 14, 2002, May 3, 2004, May 4, 2004, May 8, 2010, May 9, 2010.
May 2002 is the coldest May on record in the last 15 years in Ottawa... so yeah, you really got lucky.
And you have to go back to 1996 to see "measurable" snowfall in May in the nation's capital.
