Black & McDonald's plaque with core values

Our Founder’s Code of Business Continues to Guide Us.

W.J. McDonald had a vision for how he wanted the company to operate and grow and he established a Code of Business that guides our organization to this day.

In August 1991, in his 104th year, he reiterated these beliefs:

  • Do the job right regardless
  • Talk to the customers regularly, confirm their satisfaction
  • Make the price fair and reasonable
  • A deal is a good one only when it is good for both parties
  • Live up to your promises
  • Treat employees with respect
  • Complete jobs promptly
  • Invoice promptly, fairly, and in detail

We honour and respect W.J.’s beliefs through our current expression of Black & McDonald’s values:

  • Live and work safely
  • Do it right
  • Always improve
  • Work for one another
  • Build enduring customer relationships
  • Enable people to flourish
