Historian Alun Hughes started researching the widely-heralded father of Canadian wine as part of a larger book on Niagara's wine industry.He didn't expect to possibly rewrite history. For years, nearly every book referencing Ontario's wine history has proclaimed Johann Schiller as the so-called father of Canadian wine. The native of Germany is said to have planted wild grapes on a plot of land in what is now Mississauga, made wine and sold it to neighbours -- effectively establishing the first-ever "commercial" winery in 1811.
