I grew up in Ottawa and lived in the city for 20 years until I moved to Toronto when I was 23.   I was happily surprised that someone who has traveled the world took the time to write about Ottawa, because as you’ve mentioned it is so often overlooked.  The city centre and all the sites highlighted in this post are very beautiful, you’ve done a good job of summing it up in 5 things.  For outdoor enthusiasts Ottawa has so much to offer with green spaces, cycling paths and the Gatineau hills nearby for ski/snowboard skidoing etc. And a Rideau Canal skate is a must.
