In 1997 Dave took on yet another job, that of drama editor for Scirocco Publishing, the somewhat funky Winnipeg publishing house founded by Gordon Shillingford. While editor at Scirocco, Dave was able to bring that company's drama list into national prominence. During Dave's tenure, Scirocco writers received an unprecedented number of Governor General's awards and nominations, including two winners (Ian Ross for fareWel and Djanet Sears for Harlem Duet) as well as nominations for Lee MacDougall, Maureen Hunter, Daniel MacIvor, David Young and Theresa Tova. Scirocco's list is now selected and edited by Glenda MacFarlane and continues to be Canada's foremost publisher of drama.

During this time, Dave was also a member of CanStage's Play Creation Group, along with Ian Ross, Djanet Sears, Karen Hines and Andre Alexis. Under the encouragement of that theatre's resident dramaturge, the irrepressible Iris Turcott, Dave began work on his largest play, Walking on Water. Inspired by Thornton Wilder's Our Town, Walking on Water has thirteen characters and spans fifty years in the life of a city. It was first produced in 2000 at Winnipeg's Prairie Theatre Exchange, directed by Alan MacInnes, and then bravely remounted by Randy Read's theatre company, New Stages Peterborough, directed by Michael Waller.

Dave was the playwright in residence at both The Stratford Festival (1997) and at Massachusetts' Barrington Stage Company in 1999.

In 1998, After You, a revised version of an earlier work, was produced at New Stages in Peterborough, directed by another longtime creative associate of Dave's, Sue Miner. The play had originally been produced at playRites 94 at Alberta Theatre Projects, under the title Kawartha.

James Roy directed Dave's satire on mega-retailers, Big Box, at the Blyth Festival in 1999. James Roy was one of the co-founders of that unique festival, along with Anne Chislett, the current Artistic Director. Big Box takes on the Wal-martization of consumer culture and its devastating effect on small towns. It originally had been produced as a radio play and won the Gold Medal at the New York International Radio awards. That was the second Gold for a radio play written by Dave, the first being for Losing Paradise in 1997. A three-way co-production with the British Broadcasting Corporation and the Australian Broadcast Corporation, Losing Paradise was written with Welsh writer Rob Gittins and Paige Gibbs of Australia. The Canadian segments were produced by James Roy.
