A new owner for the Ottawa Senators has reignited buzz about where the team could play, with the mayor floating a downtown arena as a major opportunity for the nation's capital.

The proposal slated for the site just west of Parliament Hill would serve as the Senators' new home and also be comprised of mixed-use development.

A new downtown arena for the Ottawa Senators was part of the RendezVous LeBreton Group's proposal for LeBreton Flats, but that plan is in jeopardy after the NCC said the group's embattled partners could not reach a settlement in their dispute by deadline.
