How did a moose wander onto Highway 417 in Ottawa's urban west end during rush hour Thursday morning?
The large animal likely either walked from Arnprior, Ont., or swam across the Ottawa River from Quebec, according to Michael Runtz, an Ottawa naturalist.
The moose, found near the Pinecrest Road exit around 6:15 a.m., was put down after it was found to have an injured leg.
(...)"It's impossible to say where this moose came from, but the Ottawa River is very close to the Pinecrest area and ... moose are strong swimmers," Runtz pointed out.http://www.cbc.ca/news/canada/ottawa/how-did-a-moose-get-on-the-queensway-1.4755264
