Dahlia is an award-winning radio talk show host and content producer — and Canada's first nationally syndicated social media columnist. She began her radio career by broadcasting live underwater, while submerged in a 38,000-litre tank to raise money for Sick Kids. For 48 hours. And, by the by, she's deathly afraid of water. Although Dahlia's been a writer longer than she's been in radio, she hasn't written while underwater — yet.
