Even before Lee was a partner he was growing the business. In 1920 he set up the first feedlots. In the 1920s the company got some attention one morning when they drove 500 head of cattle through Edmonton and over the high level bridge from south of the city. Business was good but setbacks were looming. In 1928 the Edmonton Stockyards offices burned down. They rebuilt right away. The new two-story building had a concrete basement and a garage for 22 cars. Weiller and Williams Co. Ltd. moved into offices on the main floor, setting up shop for the next several decades.
The depression years were difficult. Henry Weiller and his brother Billy struggled to keep their businesses going. Lee bought and leased land to make ends meet. He recalled: “I didn’t have any money either. I wasn’t clear of debt until I was sixty.” He travelled all over the province looking for livestock to buy and sell, spending many nights sleeping in his Hudson automobile.
Life took another turn when Billy Weiller died. His premature death left Lee and Henry to oversee the business. The two remained partners until Henry’s death in 1956.
