Duchesnay Creek Bridge

Originally constructed in 1937, the Duchesnay Creek Bridge connects the City of North Bay and the Nipissing First Nation. In 2021, it was replaced with a one-of-a-kind structure, built using laminated, high-quality Douglas Fir girders.

Tree Planting Whitby April 2022

Tree Planting Initiative

In honour of Miller’s 105th anniversary we began working toward our goal of planting 105,000 native trees and shrubs on 105 sites over the next 10 years. Miller’s contributions to the COLAS Biodiversity program included tree planting events across three sites in 2022 – Whitby and Aurora Plants and Carden Quarry in Brechin. We are proud to announce that over the course of the three events more than 300 employees and their families in cooperation with tree planting contractors helped plant over 20,000 trees! We will need approximately 150 acres with over 700 trees per acre of land to meet our goal over the next 10 years. A strong commitment from employees is what will help us achieve that goal!

Scotiabank’s Road Hockey to Conquer Cancer is the world’s largest hockey fundraiser supporting the Princess Margaret Cancer Centre. The all-day event features hundreds of road hockey games, 150 teams and over 1,700 participants, with every supporter and player united by one common goal: to conquer cancer In our lifetime. Teams consist of rookies, seasoned veterans and prominent celebrities from across North America who all come together to support this worthy cause.
