Duchesnay Creek Bridge Hero

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.

Gardiner Expressway Resurfacing

Each year, the City of Toronto shuts down the Gardiner Expressway for a weekend to perform selective resurfacing and maintenance. Brennan Paving & Construction Ltd, a subsidiary of the Miller Group, was the successful bidder in 2021.

2023 Road Hockey to Conquer Cancer

On September 30th, the Miller Group once again participated in Road Hockey to Conquer Cancer supporting The Princess Margaret Cancer Foundation. With many returning players and some new faces, the team played in 4 exciting games and finished with a 3-1 record! The all-day event featured hundreds of road hockey games, and over 1,500 players and volunteers united by one common goal: to conquer cancer in our lifetime.

This is The Miller Group's eighth year participating in this exciting event and we once again surpassed our fundraising goal by raising $20,000! All funds raised go to The Princess Margaret Cancer Foundation for crucial research, therapies and treatments.

Ride Smart Partnership

Miller is proud to partner with the Ontario Provincial Police (OPP) in sponsoring Ride Smart, a program created by New Hope Community Bikes. The program focuses on making connections in communities throughout Ontario to educate kids on how to safely ride their bikes. The emphasis is on road safety and the importance of physical activity while building strong connections. Through this program, kids gain confidence and practice their skills, which will not only make them better bike riders but also safer drivers in the future. Continuing Miller’s long tradition of focusing on the communities where we live and work, we’re excited to contribute to this fun and equally important program.
