From a 1997 Globe and Mail article:

"While he battled the bottle, Lightfoot spent a chunk of his career dealing with turbulent relationships, including a two-year affair with Cathy Smith in the sixties, the Hamilton woman who was convicted in 1985 of administering the fatal drug overdose to comic John Belushi. Lightfoot is not eager to discuss that chapter in his life. "When you talk about all those things like that, they affect the new things that have come into your life," he says, looking at Elizabeth.
Instead, Lightfoot is more than happy to talk about his children. There are six: Fred, 34, and Ingrid, 32, from his first marriage to a Swedish woman named Brita; Gaylen McGee, 22, a student living in
Los Angeles; Eric Lightfoot, 15, who lives outside of Toronto; and Miles, 8, and Meredith, 3, from his current marriage. Lightfoot is also grandfather to Ingrid's two children: Amber, 9, and John, 7.
"We have an as normal as can be family life," says Lightfoot. "I recognize that I am family with these children."
When asked whether the entire clan has ever attended a family get-together, Lightfoot replies, "Not yet."
He's also not quite ready to pen the autobiography he's been asked about many times in the past.
"I might be able to eventually, but I'm not thinking about it right now, that's for sure. I'm still working."
****************************************
I believe he mentioned somewhere or other that Eric is a musician, though of his own kind of music. He'd be about 21 or 22 now.
Ah, found it! Excerpt with pertinent info:
"During the interview, Lightfoot politely excused himself twice to talk with his 18-year-old son, Eric, who was visiting him. Eric is starting an alternative band in Toronto.
Asked whether his son is interested in playing his father's music, Lightfoot replied, "He's not into that kind of trip. He's into his own trip."
