US foodservice giant Wendy's expects to boost the number of its Tim Hortons doughnut shops by one third by 2005. This would see the Canadian chain grow to more than 3000 stores. Wendy's, which acquired Tim Hortons in 1995, already operates nearly 2,200 doughnut shops, of which 2,050 are in Canada. It plans to open 170-180 news stores in Canada in each of the next few years.
