In the Canadian province of Ontario, then-Premier Dalton McGuinty announced a "locked door" policy, as part of a Safe Welcome Program at all elementary schools as of September 2013.[48] About 2,450 elementary schools applied for and received funding from the province to install front-door buzzers and security cameras. Together with the 850 schools that installed them with provincial funding in 2005, the new equipment means about 80 per cent of Ontario's 4,000 elementary schools will have secured front doors.[49] In the Greater Toronto Area, 1,287 schools received funding through their 12 school boards such as the Toronto Catholic District School Board, Toronto District School Board, Durham Catholic District School Board, and York Region District School Board.

Every Ontario school board is required to have a local police-school board protocol, which includes a lockdown plan that is practised at least twice each year. Professional development and training has been made available to school and board staff, along with their local police services, to put the protocol in place at both the elementary and secondary levels.[50]

On December 16, 2012, every NFL team held a moment of silence in honor of the Sandy Hook victims and lowered their flags to half-mast. Many teams put Newtown or "SHES" decals on their helmets. The New England Patriots launched 26 flares into the night sky.[55] The Patriots also took the muskets away from its "End Zone Militia"—Revolutionary War re-enactors who celebrate every score with gunfire. The team felt the memory of the shooting only 150 miles away was too fresh in people's minds for the sight of firearms and the smell of gunpowder.[56] Victor Cruz of the New York Giants was the idol of one of the child victims, Jack Pinto. After learning that Jack's family planned to bury their son in a Victor Cruz jersey, Cruz called the family and wrote "RIP Jack Pinto" and "Jack Pinto my hero" on his shoes during the December 16 game against the Atlanta Falcons. He later travelled to Newtown and visited with the Pinto family.[57] The Sandy Hook Elementary Choir was invited to sing "America the Beautiful" with Jennifer Hudson at the pre-game ceremonies at Super Bowl XLVII on February 3, 2013.[58]

The Sandy Hook Elementary School shooting prompted renewed debate about gun control in the United States, including proposals for making the background-check system universal, and for new federal and state legislation banning the sale and manufacture of certain types of semi-automatic firearms and magazines with more than ten rounds of ammunition.

Within hours of the shooting, a We the People petition was started asking the White House to "immediately address the issue of gun control through the introduction of legislation in Congress,"[66][67] and the gun control advocacy group the Brady Campaign to Prevent Gun Violence reported that an avalanche of donations in the hours after the shooting caused its website to crash.[68] Five days later, President Obama announced that he would make gun control a "central issue" of his second term,[69] and he created a gun violence task force, to be headed by Vice President Joe Biden.[70] On January 16, 2013, Obama signed 23 executive orders and proposed 12 congressional actions regarding gun control.[71] His proposals included universal background checks on firearms purchases, an assault weapons ban, and limiting magazine capacity to 10 cartridges.[72][73]

On December 21, 2012, the National Rifle Association's Wayne LaPierre said gun-free school zones attract killers and that another gun ban would not protect Americans. He called on Congress to appropriate funds to hire armed police officers for every American school and announced that the NRA would create the National School Shield Emergency Response Program to help.[74] After LaPierre's press conference, the Brady Campaign asked for donations to support its gun control advocacy and asked NRA members "who believe like we do, that we are better than this" to join its campaign.[75] On January 8, 2013, former Congresswoman Gabrielle Giffords, who was shot and injured in a 2011 shooting in Tucson, launched Americans for Responsible Solutions to raise money for gun control efforts to counter the influence of powerful pro-gun groups such as the NRA.[76]

On January 16, 2013, New York became the first U.S. state to act after the shooting when it enacted the Secure Ammunition and Firearms Enforcement (SAFE) Act.[77] On April 4, 2013, Connecticut and Maryland both enacted new restrictions to their existing gun laws.[78][79] Ten other states had passed laws that relaxed gun restrictions.[80]

Legislation introduced in the first session of 113th Congress included the Assault Weapons Ban of 2013 (AWB 2013)[81][82] and the Manchin-Toomey Amendment to expand background checks on gun purchases.[83][84] Both were defeated in the Senate on April 17, 2013.[85]

During the investigation into Adam Lanza's background, officials found that Lanza had possessed "thousands of dollars' worth of violent video games".[86] Though the link between Lanza's video game habits and the shooting was not yet clear from the investigators,[87] the findings reopened debate on the hypothesized connection between violent video games and real-world crime.[88]

Senator Jay Rockefeller called for regulation of the video game industry shortly after the shootings.[89] In mid-January 2013, representatives from the video game industry met with Vice President Biden on the subject of violent video games and their regulation.[87] In late January, Representative Jim Matheson reintroduced legislation that he had been attempting to pass that would require stores to post notices about video game ratings and restrict sales of mature and adult games to children.[90]

The Entertainment Software Association published a statement offering its condolences to the families and stating "The search for meaningful solutions must consider the broad range of actual factors that may have contributed to this tragedy. Any such study needs to include the years of extensive research that has shown no connection between entertainment and real-life violence."[91] The ESA retained professional lobbyist firm Brown Rudnick Government Relations Strategies, run by former Connecticut House Speaker Thomas D. Ritter to represent their interests with the state legislature.[92]

Private equity fund Cerberus Capital Management, the owner of firearms manufacturer Remington Outdoor Company, the manufacturer of the Bushmaster brand AR-15 style rifle used in the shooting, announced its intention to sell Remington. In 2015, unable to find a buyer for Remington, Cerberus notified investors it would permit them to cash out.[93] In 2018, Cerberus turned over Remington to bankruptcy court in Delaware.[94]

Days after the shooting, California State Treasurer Bill Lockyer ordering an accounting of investments in gun manufacturers from California's teacher pension system California State Teachers' Retirement System (CalSTRS) and public employee pension system California Public Employees' Retirement System (CalPERS).[95] On January 9, 2013, the Teachers' Retirement Board Investment Committee directed staff to "begin the process of divestment from firearm companies that manufacture weapons that are illegal in California."[96] In 2013, CalSTRS divested from Sturm Ruger and the American Outdoor Brands Corporation (formerly Smith & Wesson).[97] CalSTRS divested from Remington; completion of the divestment from Remington was delayed until 2015 due to contractual obligations regarding CalSTRS's investment in a private equity pool managed by Cerberus.[98]
