Erin Davis remembers daughter's 'large, short life' ahead of Toronto memorial

Lauren Davis was just 24 years old when she died in her sleep after her first Mother's Day, but her young age didn't stop the popular Ottawa radio host from living what her mother describes as "a large, short life."

Lauren Davis's mother, CHFI Toronto radio personality Erin Davis, prepared to celebrate the radio personality's life at a memorial Friday in Toronto — by "sifting through pictures" and "combing through memories" of her daughter, and expressing grief in an emotional entry in her public journal.

"If you were to ask us even today, as we huddle together shrouded in grief, whether we'd choose to eschew this deep sadness and pain if it meant we didn't have our one and only child, we'd have to say, 'No!'," Erin wrote in Thursday's entry.

"As someone wise said, pain is the price you pay for love."

Lauren Davis was on maternity leave from her role as the midday news anchor and host of Ottawa Noon on 580 CFRA at the time of her death, apparently from a "cardiac event" that remains unexplained.

She and husband Phil Shirakawa welcomed the birth of their son Colin last October.

Toronto memorial

Friends and family are gathering Friday for a 1 p.m. ET service at the Royal Conservatory of Music's Koerner Hall.

Co-workers of both Lauren and Erin Davis are also expected to attend.

Vocalist Dan Clancy (lead singer of Canadian rock band Lighthouse) is slated to perform a version of Billy Joel's Lullabye, with special lyrics by Erin Davis. 

The public is invited to watch a livestream of the event online.

A service was held earlier this month in Ottawa for Lauren Davis's Ottawa co-workers and friends.

As co-host of 98.1 CHFI's morning show, Erin Davis is a popular figure in Toronto.

The 52-year-old frequently invites listeners to share in her life through her online journal and by recording special broadcasts from her home, which she shares with husband Rob Whitehead.

One week after Lauren's birth in 1991, the station set up remote equipment in Erin Davis's home so she could continue her broadcast work for three weeks "with her baby in her arms," the memorial program reads.

"Just as her sudden departure would 24 short years later, Lauren made national news for her on-air presence."

Suffered a 'catastrophic cardiac event'

While mourners are able to pay tribute to Lauren Davis at Friday's memorial, the family is still unable to hold a funeral.

The initial coroner's report was inconclusive, and plans for a funeral are being held up by "intricate medical examinations" into her death, explained a newsletter to CHFI's "loyalty club" listeners earlier this month.

In Erin Davis's message to fans Thursday, she acknowledged how difficult it was to have "no answers about what caused Lauren's catastrophic cardiac event."

"Trust me, we ask the very same questions," she writes. "But even answers won't bring our girl back. And so we go on."
