Our Story

One man's journey to Canada begins a family legacy of innovation.

Since its creation in 1887, Walker has continually developed and evolved by turning problems into solutions. This innovative spirit passed down through five generations of the Walker family has secured our ability to grow as a business and as a community partner.
