We've reached the end of an era. What started out in 1964 as a tiny cabinet shop and became what is now Petersen's Building Supplies will be closing its doors to the public on February 1, 2026.

As a local, family-owned business, we're grateful for the customers that trusted us for more than 50 years.

Thank you Thunder Bay!
