🎉Welcome to the NEW official NDBS page! 🎉

While our old page is still visible, our team unfortunately lost admin access to it. Rather than sitting on our hands, we built a brand new page right here so we can keep sharing store updates, local promos, and project advice!

To get things rolling and catch up with our amazing community, we are throwing a welcome back giveaway! One (1) lucky local winner is going to take home a fantastic prize bundle:

☕ $25 Tim Hortons gift card
🔨 $50 NDBS gift card
👕 Selection of official NDBS swag

WE WANT TO HEAR FROM YOU!
To enter, just drop a comment below with a favourite NDBS memory, a home project you tackled with our team's help, or your best in-store experience over the years. Whether it was a backyard deck build, a quick stop for a box of hardware, or just a morning chat in the aisles, we would love to read about it. ❤️

Every meaningful story counts as an entry, so feel free to share more than one. We would also appreciate your help softly spreading the word to neighbours and friends so they can find their way back to our official home for store updates & promotions.

Make sure you are following our new FB page and IG account so you can see if you are the lucky winner when we make the announcement on Sept. 1!
