The Senators will be armed with their own nuclear deterrent for this round of the Battle of Ontario.

As the Senators prepare to close out a five-game homestand Saturday at Scotiabank Place against the Toronto Maple Leafs, newly-acquired winger Matt Kassian is preparing to make his debut in the provincial punchup.

Twenty-four days ago in enemy territory at the Air Canada Centre, Senators GM Bryan Murray decided he'd seen enough after David Dziurzynski was knocked out by Toronto's Frazer McLaren. Days later, he acquired Kassian.

While Dziurzynski suffered a concussion and has returned to the minors, the Senators have served notice that Toronto's Colton Orr and McLaren will have to answer to rugged winger Chris Neil or Kassian if they try anything silly.

Kassian, choosing his words carefully after a short skate at the Bell Sensplex on Good Friday, knows games like this are why Murray gave Minnesota Wild GM Chuck Fletcher a sixth-round pick in 2014.
