The film was shot in two main regions — Boston, Massachusetts, and Ontario, Canada — combining authentic Boston landmarks with cost-effective Canadian locations. As a spin-off of the long-running series Blue Bloods, the show follows Detective Danny Reagan after he moves from New York to Boston to join the city's police force. The production team extensively used iconic Boston locations such as Faneuil Hall, the Longfellow Bridge, and Fenway Park for establishing shots and key action scenes, while relying on Toronto and its suburbs for interior scenes and neighborhood settings. Locations in Ontario, including the Etobicoke, Mississauga, and Scarborough areas, were chosen for their lower production costs and generous Canadian tax incentives, although some viewers from the Boston area noted that the Toronto stand-ins do not always convincingly replace real Boston neighborhoods. The series blends crime drama and family dynamics, with Danny navigating a new city and a new precinct.

Filming Locations:

Spaulding Rehabilitation Hospital (Exterior of Boston General Hospital)

In the Film

Scene where the exterior of Boston General Hospital is shown, with the hospital's name digitally superimposed on the facade of the real building. This establishing shot appears at the beginning of the series to denote an important recurring location.

In Reality

The scene was filmed in Boston's Charlestown Navy Yard, using Spaulding Rehabilitation Hospital as the exterior of the fictional Boston General Hospital. The hospital's name was added digitally in post-production. This modern waterfront rehabilitation center opened in 2013 and stands prominently on the harbor with a view of the Zakim Bridge.

Washington Street and Granary Burying Ground

In the Film

Scene where Detective Danny Reagan chases a suspect down Washington Street in downtown Boston in the first episode, 'Faith and Family.' The foot chase goes through Granary Burying Ground, weaving between historic tombstones at one of the city's oldest cemeteries.

In Reality

The scene was filmed in downtown Boston on Washington Street and near Granary Burying Ground, one of the city's most historic cemeteries dating back to 1660, where notable figures such as Samuel Adams are buried. This is Boston's central commercial district and one of the city's oldest streets.

The Annex Neighborhood in Toronto (Erin's House)

In the Film

Scene where the exterior of Erin's house is shown, styled as a mansion in Boston's Beacon Hill neighborhood. Despite the creators' intent, some viewers from the Boston area noted that the architectural style and surrounding street differ noticeably from actual homes in Back Bay or Beacon Hill.

In Reality

The scene was filmed in Toronto's Annex neighborhood, a historic district with late Victorian and Edwardian architecture. The Annex is located just north of the University of Toronto campus and features tree-lined streets and well-preserved historic homes. It was used as a Beacon Hill home in Boston for the series.
