"Contractors rarely visit the Home Depot"
That is not true, i lived in Calgary for ~17 years and my family has been in the Calgary business community for over 50 years. Revy/Rona even has a contractors entrance to facilitate large purchases and IIRC home depot does also. Trust me they are used and used well, i have witnessed it with my own eyes and even know several contractors in the city who do framing, masonry and carpentry.
If someone can cough up suljas rental addy i can have all pertinent public info in a flash , pictures even :)
