A park that was actually close enough to see the planes on one of the main runways, like
Jacques-de-Lesseps Park in Montreal,
Jacques-de-Lesseps Park is the official plane spotting location at Montreal airport. Read this article to learn more about photographing aircraft there.

might have made more sense than one
miles away that people i
gnore and instead go to spots like Renforth Drive, Dixie Road, or Airport Road to stand on sidewalks or in parking lots.
Or, instead of an entire park, why not just some of those small viewing mounds or platforms in acceptable locations that could be used by the plane spotters for views unimpeded by fences and passing trucks? Maybe sponsors could pay to build and put their names on them -- the CIBC, Wendy's, Tim Horton's, FedEx, or Air Canada viewing mound or platform.
It appears Emirates has returned to using Airbus A380 planes on their
Toronto flights instead of the Boeing 777.
It looks like the only other passenger quad-jets left flying into Pearson are the
A340s used by Lufthansa, though sometimes they're using the twin-jet A330 (Edit: A month later, and it looks like it's now an A330 most or all of the time).
There are still cargo versions of the Boeing 747, and the FedEx MD10 or MD11 tri-jets at Pearson on most days.
Edit: Apparently it is possible to record video from Danville Park of planes landing and taking off at Pearson on a clear day, if you have a very expensive zoom camera.
