A comprehensive resource for safe and responsible laser use
The Airbus A319 had 113 passengers onboard when the incident occurred in November 2017. The captain was able to safely land the aircraft.
The report said that several other aircraft also reported laser light at the same point in their approach, for two nights in a row. The light was reported to be coming from persons in a park.
From mid-November to December 6 2017, there were 23 laser illuminations of commercial aircraft in the Toronto area. Nationwide, there were 381 laser strikes as of the first week of December 2017, down from the approximately 600 incidents reported in 2015 and 2016.

An infrared camera onboard the aircraft helped the crew locate the source of the laser beam. Ground officers found the pellet gun, which 19-year-old Nicholas Caranci had thrown to the ground as he ran away. The IR camera helped the helicopter crew direct officers to the teen’s location.
In an attempt to escape arrest, Nicholas Carianci ran from the court at right and hopped over a fence, after throwing his pellet gun with a laser sight into weeds (green circle). Thanks to the helicopter IR surveillance camera, police were able to pick up both the teen and the pellet gun.
Caranci was arrested and charged with mischief endangering life, unlawfully engaging in behavior that endangers an aircraft, and projecting a bright light source into navigable airspace.

The pilot was able to identify the source location of the laser. He then landed and sought medical treatment.
Ground officers stopped a vehicle and arrested the man.

A video taken from the helicopter is at the York Region link.
The April 21 2012 incident happened in Uxbridge, 75 km northeast of Toronto. It was looking for vandals when struck by a laser numerous times over several minutes. The helicopter set down at a nearby police station, and the pilot was taken to a hospital. He was released with no apparent damage, but a police spokesperson said it could take several days for damage to emerge.
20-year-old Melissa Perry of Uxbridge was arrested, and charged with lessening the ability of a crew member to perform duties, interfering with the duties of a crew member, projecting a bright light at an aircraft, mischief endangering life, assault with a weapon and common nuisance. It is unclear from news reports whether Perry was associated with the vandals.

Analysis from LaserPointerSafety.com: If the laser is really Class 3A (less than 5 mW maximum power), the pilot’s eyes were unharmed. The Nominal Ocular Hazard Distance for a 5 mW laser with a tight 1 milliradian beam is 52 feet. This means that laser safety experts have concluded that no eye injury could occur past 52 feet. If the pilot was airborne, his eyes were likely much farther than 52 feet from the laser. (Global Toronto reported the helicopter was at 5000 feet, but that is very high for vandal surveillance; 500 feet is more reasonable.)
Plus, as explained on the Laser Safety Calculations page, there are additional factors that go into the NOHD. The result of these factors is that a 5 mW laser would have to be within 16.4 feet of a person’s eyes before there was a 50/50 chance of causing a minimally detectable eye injury. This is not opinion; this is scientific fact based on how the NOHD is derived.
UPDATE, NOVEMBER 2012: On September 21 2012, Perry pleaded guilty to one charge of violating the Aviation Act by shining a bright light at an aircraft. She was fined $500. All other charges were dropped by the Crown. From DurhamRegion.com.
CTV Toronto reported that "[t]his is estimated to be the sixth such incident in Toronto in the past year. About a dozen have occurred in Ontario, and more than 30 across Canada."
