Akin's career began in 1993 with The Packet and Times in Orillia, Ontario as the paper's city hall reporter. In 1995, he moved to The Chronicle Journal in Thunder Bay, Ontario where he worked as a senior reporter and joined the The Hamilton Spectator and then the National Post, followed by The Globe and Mail.
From 2001 to 2008, Akin was a parliamentary correspondent for CTV News before joining Canwest News Service (now known as Postmedia) as a national affairs correspondent. At CTV, Akin won a Gemini Award for his reporting. The Globe and Mail reported that he resigned from Canwest on June 10, 2010, to become the first reporter for Sun Media's new all news cable service.  From 2011 to 2015 he was the national bureau chief for Sun Media and the Sun News Network and hosted the The Daily Brief and, later, the hour-long prime time show "Battleground"
Canadian playwright Michael Wheeler characterized Akin as having "broke ranks" with the rest of the Parliamentary press gallery when he asked the Prime Minister about Homegrown prior to its opening night. According to Wheeler all reporters had agreed upon a question about a prominent issue of the day which they would all ask if they were called upon for a question from the Prime Minister.

The trouble started last August, when Sun Media’s David Akin broke ranks with the media pool. With the rest of the journalists at Rideau Hall agreeing to ask Prime Minister Stephen Harper a question about the long-form census, Akin used one of two English-language questions available to the press to ask about Catherine Frid’s play Homegrown, which had just played at SummerWorks.mirror

But if this play really is, as Frid and Summerworks advertise in their promotional material, about 'separating fact from hype in the face of the uncertainty, delays and secrecy in his case', then much more is needed from the playwright.mirror
