The backstory: There is legislation called the “Canada Heritage Act”—although it isn’t consistently applied across all books (some types of books, e.g., textbooks, books without pictures, etc. get treated differently than others) the long and short of it is that it basically prohibits The Wood Database from shipping books to Canada through Amazon.com.
Potential workarounds: Use a package holding/forwarding service like Kinek or Borderlinx.
If you’ve got a new or unusual wood species that isn’t on the site, please consider sharing it with the rest of us! I’m also interested in getting photos of completed wood projects—especially of obscure or lesser known woods. See my page on donating wood samples for more info.
If you’ve been helped by the Wood Database, consider saying “thanks” and helping to support the project. There is of course no obligation, but if you’d like to give back and ensure that the project continues to grow, consider supporting me on Patreon.
