I can see the Leslie Spit/Tommy Thompson park from my balcony and I've been perplexed as to why there are no leaves on the trees on parts of the spit.
Late one night last winter I was watching one of those new "free trial" HD channels, I think it was the Oasis channel. One episode dealt with all of the bird life in Toronto which was kind of interesting. They also covered the Comorant birds and the damage they are inflicting on the trees at Tommy Thompson park where they settle and breed which finally answered my long standing question.
I read some years ago that to help control the seagull population the City has (had?) teams who put oil on eggs where seagulls nest which kills the egg thus keeping the population under control. The link to the article below also suggests this which I think it a much more acceptable alternative than shooting the birds.

Cormorants are an interesting example of a wildlife recovery program perhaps being too successful. They were almost wiped out by DDT, and efforts were made to re-introduce them. Now we're left thinking about how to reduce their numbers. How ironic.

Hamilton Harbour and Cootes Paradise are just full of them. You can see man-made islands covered in cormorants from the Hamolton Skyway bridge.
 
Same with Canada Geese. They had to be reintroduced here, and their population has since exploded to the point they are a nuisance.
 
Mmmm Cormorants over lime rice with Swan nuggets on the side
