The popular Frenchman died in a training accident
in Nakiska, Canada earlier this month ahead of the first speed event, which was won by Switzerland's world downhill champion Beat Feuz.
The 30-year-old beat Olympic champion Matthias Mayer of Austria by just under one tenth of second.
Norway's Aksel Lund Svindal, who missed most of last season following knee surgery, finished in third.
Feuz, who also won downhill bronze at the worlds in 2015, clocked one minute 43.76 seconds to triumph on the Alberta track, which was shortened because the landing off the first jump was not deemed safe.
"Beginning the season with a win is the best thing that can happen," Feuz told reporters.
"I had a great summer preparation, without any injuries and am very happy about how things turned out here, especially as I'm not performing very well here usually."
The 27-year-old Mayer drew on past experience of three podium places in super-G races at Lake Louise to score another top three.
Svindal, 34, who won Olympic downhill silver and super-G gold in 2010, also missed much of 2016 with a knee injury and was happy just to be back on the circuit.
"(The knee) is not awesome, but racing is racing," the two-time downhill world champion told reporters.
"You don't get old in sports, it's more about injuries you have. In the end, there's just too much stuff that's not working the way it should."
Svindal's close friend and countryman Kjetil Jansrud hit back from fifth in the downhill to clinch Sunday's super-G under light snow and rain at Lake Louise.
Jansrud, 32, the defending Olympic super-G champion, edged Austrian duo Max Franz (+0.28 secs) and Hannes Reichelt (+0.32 secs) to claim the season-opener.
Svindal was fifth behind compatriot Aleksander Aamodt Kilder, while Feuz finished 12th.
German slalom specialist Felix Neureuther is out for the season and will miss the Winter Olympics after tearing a cruciate ligament in his left knee during training at Copper Mountain, Colorado Saturday.
The 33-year-old won the season-opening slalom in Levi, Finland and was one of the main contenders for slalom gold in PyeongChang, South Korea in February.
"I've had some setbacks in my career and I know how to deal with them, so I wish our team all the best for the season," he said.
On the women's circuit, US star Mikaela Shiffrin won Sunday's slalom in Killington, Vermont after finishing second behind Germany's Viktoria Rebensburg in the previous day's giant slalom.
Shiffrin, the overall World Cup champion last season, put down two impressive runs to score her 26th World Cup slalom victory in front of her home crowd.
The 22-year-old Olympic champion beat Slovakia's Petra Vlhova by 1.64 seconds with Austrian Bernadette Schild 2.67 secs back in third.
Rebensburg, the 2010 Olympic giant slalom champion, also won the season-opening giant slalom in Soelden, where Shiffrin finished a disappointing fifth.
