In the summer of 1948, while taking a break from his studies, Pattison was employed at Richmond Motors in the southern Vancouver suburb of Richmond, British Columbia. Although he was primarily responsible for washing cars, his job also involved selling them. In summer 1949, he worked for Kingsway, a used car dealer in Vancouver. "I worked there all summer and then [my boss] gave me a car to drive to university. So, I then started to sell used cars at UBC," Pattison told a reporter. In 1961 he was able to persuade a
Royal Bank manager to lend him $40,000, To complete the funding, he also sold his house, assigned the cash surrender value of his life insurance policy to General Motors and took a loan from GM for $190,000 for preferred shares in the company. His company owned 25 car dealerships as of March 2018,
Peterbilt truck dealerships,

If you like your work, it’s not work." In 2026, Jim Pattison Developments announced intentions to sell a 550,000 square foot warehouse to a US government contractor. The company claims they were not aware the warehouse was to be used as an
ICE detention camp. On January 30, 2026, the company announced the deal was cancelled, after sustained public pressure from BC Green Party leader
