Every Tuesday, theScore's hockey editors will examine the fortunes of the north's seven NHL franchises. Welcome to "O Canada."

Calgary Flames

Trade: Acquired defenseman Michael Stone from the Arizona Coyotes for a 2017 third-round pick and a 2018 conditional fifth-round pick. Arizona also retained 50 percent of Stone's salary.

Grade: B-

Stone has jumped onto the Flames second defense pairing alongside T.J. Brodie with solid results to date. In four games, he's recorded two assists, and seven shots, albeit with a five-on-five Corsi rating of 42.8. He's also helping in the plus/minus department, for those who still care about the stat.

Calgary also further shored up the blue line with the signing of Matt Bartkowski.

Edmonton Oilers

Trade: Nothing, yet

Grade: Incomplete.

General manager Peter Chiarelli hasn't made a trade since sending Nail Yakupov to St. Louis prior to the start of the regular season, preceded by the infamous Taylor Hall-Adam Larsson deal.

Barring a complete collapse, however, the Oilers appear to be a lock for a playoff spot, and could secure home ice in the first round with a second-place finish in the Pacific.

A clear need exists at the backup goalie position, as Cam Talbot continues to carry a heavy workload and could use some rest down the stretch.

Montreal Canadiens

Trades: Acquired Jordie Benn from the Dallas Stars for Greg Pateryn and a 2017 fourth-round pick.

Grade: C-

GM Marc Bergevin followed up the hiring of Claude Julien as head coach by adding some depth on the blue line, which is fine, except it doesn't address the team's biggest need.

That would be down the middle, where Martin Hanzal appeared to be a perfect fit. Instead, the center was sent to Minnesota by the Coyotes, leaving Montreal with the prospect of heading into the playoffs with Phillip Danault, Alex Galchenyuk, Tomas Plekanec, and David Desharnais rounding out the depth chart. No one foresaw Danault centering the first line, while Plekanec and Desharnais have been playing well below expectations.

Still time to get something done, though.

Ottawa Senators

Trade: Acquired Alex Burrows from the Vancouver Canucks for prospect Jonathan Dahlen.

Grade: D

Not only did Ottawa trade a promising draft pick for a player who will turn 36 by season's end, they're also reportedly set to sign Burrows to a two-year contract extension before he even dons the team's jersey.

The Senators appear headed for the playoffs and see Burrows as an effective depth forward who can mix things up, kill penalties, and score the odd goal. That's certainly how he used to be defined, but at this stage in his career, the return on investment hardly seems worth it, especially when Dahlen compares favorably to a player currently tearing up the NHL.

Toronto Maple Leafs

Trade: Acquired forward Brian Boyle from the Lightning for forward Byron Froese and a 2017 second-round pick.

Grade: B+

One year removed from finishing dead last in the NHL, the renaissance is on in Toronto, and the Maple Leafs are buyers with a view to their second playoff appearance since the lost season of 2004-05.

Boyle brings a wealth of playoff experience after making two trips to the Stanley Cup Final in recent years, and gives Toronto solid depth down the middle behind Auston Matthews, Nazem Kadri, and Tyler Bozak.

The trade value will rise even further if Boyle - who seems excited about the opportunity - can re-sign with the team in the offseason.

Vancouver Canucks

Trade: See aforementioned deal with Ottawa.

Grade: A

The best way to grade this trade is to check in on the social media reaction. Praise was heaped on GM Jim Benning while shade was thrown at Ottawa immediately after the deal was announced, and the hits just kept coming.

Winnipeg Jets

Trade: *crickets*

Grade: Incomplete

This may come as a shock, but GM Kevin Cheveldayoff has yet to tinker with a roster set to once again fall short of the postseason. In fact, the biggest move made recently was to recall exiled goaltender Ondrej Pavelec from the AHL, to zero positive effect.

The Jets are only five points out of a playoff spot, but should be looking to sell, as they did last year with Andrew Ladd. Soon-to-be unrestricted free agents Drew Stafford and Paul Postma are the obvious candidates to be moved, with Pavelec also a possibility in the unlikely chance there's any takers.
