On this week's episode of the PROFIT BusinessCast, Drew Green, CEO and founder of SHOP.CA, talks about where ecommerce is headed in Canada. A 15-year veteran of digital media and ecommerce, Green ran American shopping site shop.com until it was acquired, and then turned his attention to the underserved Canadian market. He couldn't understand why billions of dollars were being spent across the border online when that money could be staying in Canada. "About half of the purchases we make are on U.S. sites—that's about $11 billion last year," says Green. So he created a shopping site specifically for Canadians, mimicking the more transparent, straightforward design of American shopping sites.
