Interesting name. I don’t know if any of these reasons inspired the powers-that-be to name it as such, but I’m guessing it’s after the Aleut from the Aleutian Islands of Alaska, based on some of the surrounding streets named after other aboriginal peoples such as Mohawk Crescent and Sioux Crescent. Similar to the area of streets in Gatineau named after aboriginal groups, both neighbourhoods appear to have originally been developed around the same time, an assumption I’m making based on their period styles.
But before we get there, here’s an interesting building one happens upon en route along the Ottawa River Pathway. It’s the Belltown Dome. There’s a skating rink inside. It’s cramped, but very special in it’s uniqueness. My son has had hockey practice there so I got to go inside.
Aleutian Drive has great trees, like this huge oak.
Nanaimo Drive has a number of unique single-story houses such as this.
Heading East towards Greenbank Road, one comes across many two story houses with decorative shutters.

That Belltown dome has got to be the worst “indoor” rink in Canada. It is too small even for Atom sized kids to play 5 on 5 and it is absolutely FREEZING inside. The changerooms… or rather the add-on cubicles, are actually construction site trailers, stink and aren’t even properly attached to the building.
For an organization such as ORSA or RAIC to actually suggest praise for this place is pretty indicative about the way some academic architects think – it looks interesting and who cares if doesn’t actually function properly to the people who use it.
The Belltown Dome was originally intended as a covered community skating rink in the winter and a fitness space in the summer, as per comments by neighbourhood residents in these City council minutes. It’s use as a hockey practice rink seems to have evolved with time and demand. http://ottawa.ca/calendar/ottawa/citycouncil/occ/2008/10-22/cpsc/06-%20ACS2008-CPS-PAR-0008.htm
With this in mind, I concur with RAIC on recognizing it as an architectural gem in our urban landscape. I appreciate it’s also a difficult perspective to maintain while cramped and freezing rink side on an early February morning watching kids hockey practice.
