Consider yesterday's flurry of NHL news — former Norris Trophy winners Zdeno Chara and P.K. Subban retiring; Nathan MacKinnon becoming the league's highest-paid player — your wake-up call: hockey season is upon us. With summer officially ending today and training camps opening this week, here's a quick catchup on how the seven Canadian teams spent their off-seasons:

Calgary Flames: For better or worse, no one had a more interesting summer than the Flames. It started with their two best players, 40-goal men Johnny Gaudreau and Matthew Tkachuk, deciding they wanted to leave the Pacific Division champs. GM Brad Treliving would have been forgiven for plunging into rebuilding mode, but instead he went on the attack, acquiring NHL assists leader Jonathan Huberdeau from Florida in the trade forced by Tkachuk and signing two-way centre Nazem Kadri in free agency. Whether this reload works or not, you have to respect the hustle.

Edmonton Oilers: Powered by an incredible post-season for Connor McDavid (33 points in 16 games) and Leon Draisaitl (32 points), Edmonton advanced to the third round for the first time in the McDavid era. They got blown out of the water there by eventual-champion Colorado, but the hope is that new goalie Jack Campbell (five years, $25-million US) brings some much-needed stability to the crease. GM Ken Holland also made a big bet on Evander Kane, handing the notoriously volatile forward a four-year, $20.5M deal after he scored 13 goals in 15 playoff games.
