Events of National Historic Significance () are events that have been designated by Canada's Minister of the Environment, on the advice of the Historic Sites and Monuments Board of Canada, as being defining actions, episodes, movements or experiences in Canadian history.
To be designated, an event must have occurred at least 40 years ago; events that continue into the more recent past are evaluated on the basis of what occurred at least 40 years ago.
As of September 2010, there are 417 designated Events of National Historic Significance.
Canada has related programs for the designation of "National Historic Sites of Canada" and "Persons of National Historic Significance". 
On 26 October 2011, the Rijksmuseum unveiled new, sustainable LED lighting for "The Night Watch".
With new technology, it is the first time LED lighting has been able to render the fine nuances of the painting's complex color palette.
The lighting was developed by Philips Lighting and was inaugurated by Rijksmuseum Director Wim Pijbes and Philips President and CEO Frans van Houten.
Rogier van der Heide, Chief Design Officer at Philips Lighting, was responsible for creating the system.
The new illumination uses LED lights with a color temperature of 3,200 kelvins, similar to warm-white light sources like tungsten halogen.
It has a color rendering index of over 90, which makes it suitable for the illumination of artifacts such as "The Night Watch".
Using the new LED lighting, the museum saves 80% on energy and offers the painting a safer environment due to the absence of UV radiation and heat.
The 2011 Turkish Riviera mass alcohol poisoning was an event that occurred on May 26–27, 2011 during a party on a yacht voyage of mostly female Russian tourists on the way from Bodrum to Antalya, southwestern Turkey.
It led to death of five people, and the hospitalisation of twenty others, some in critical condition, after consuming alcoholic drinks mixed with methanol, served at the yacht's bar. 
The first footrace on the walkway occurred the day after the official opening on October 4, 2009.
The 5k race started on the Highland side, crossed to the Poughkeepsie side and turned around at the parking lot and finished back in Highland.
The race was won by James Boeding in a time of 16:26.
The female winner was Kira DeCaprio in 20:12.
There were 660 recorded finishers of the race.
The 5K race, called "Treetops to Rooftops", has become an annual event, organized by the Mid-Hudson Road Runners Club.
On May 15, 2010, there was a lighting ceremony as LED-based lights were turned on for the first time, designed to allow nighttime use of the bridge, though due to funding limitations this is expected to only be used on special occasions.
3000 people paid $5 apiece to attend the sold-out ceremony.
Crowd management presented a problem, prompting criticism and an apology from the Walkway organization, but ultimately no incident or injury.
On February 20, 2011, Don Kampfer, a Korean War veteran, died of a heart attack he suffered while participating in a monthly ceremony to retire and replace the American flag on the Walkway.
Kampfer is the second person to die on the Walkway, the other also being of a heart attack while walking over the bridge.
On July 27, 2011, an Ulster County man in his late 20s is reported to have jumped off the bridge in the evening after it closed.
His entry to the bridge set off an alarm bringing the police, who found his belongings (and later a suicide note at his home), but he was not there; his body was found two days later.
Though typically closed at sunset each day, the Walkway often has events after sundown.
Some of these openings (such as for Independence Day and in December) include fireworks displays.
In July 2012, in a photograph taken from the Walkway, an amateur photographer captured what the New York Daily News described as a "breathtaking juxtaposition", capturing fireworks and a bolt of lightning in the same image.
Some of the night time events have featured members of the Mid Hudson Astronomical Association, who have provided telescopes for public viewing of the moon, stars, and planets from the Walkway.
