In a sign of strong demand, Canada's leading quick service restaurant chain Tim Hortons increased the range for its upcoming IPO by 21% from $18-$20 to $22-$24. The amount of shares to be offered remains unchanged at 29 million. Tim Hortons, which currently operates 2,597 restaurants in Canada and 288 in the US, is being spun off from Wendy's. Joint book-running managers Goldman Sachs and RBC Capital Markets are expected to price the deal on Thursday evening.
