Both Lightfoot and Howe by the last couple of decades of their lives had a low profile with any Canadian who is younger than I am (1967). I’d argue the death of Gord Downie (lead singer of the Tragically Hip) was bigger news here than the death of Howe. Howe and Lightfoot would be thought of more like other national icons like Joni Mitchell, Anne Murray and (maybe) Margaret Atwood.
Bigger names within Canada are Don Cherry, Orr, Gretzky, Lemieux, The Rock, Chris Hadfield Celine Dion, Shania Twain, Ryan Reynolds.
