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.

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.
