The CRJ900 aircraft, which was being operated by Jazz Aviation on behalf of Air Canada Regional, was en route from Montreal carrying 72 passengers and four crew.
The New York and New Jersey port authority and LaGuardia airport said the fire engine had been responding to a separate incident at the airport when the collision happened at around 11.40pm.
LaGuardia is currently expected to remain closed until at least 2pm local time on Monday (23 March) according to the US Federal Aviation Administration, which has stressed an initial ground stop order is likely to be extended.
