NYC to Toronto for $44-59USD one way!

Vayama.com is having a sale--the first 1K people that use the FLASH40 promo code on the payment information screen to get $40 off the flight.  This deal is good for any international flight originating from the States so it's best to use for a one-way, and use the code for only one ticket, so if you need to book three tickets, book each one individually and use the code each time at checkout!
To Toronto from either JFK (flying TAM business class for $59, the Brazilian airliner that is allowed by open-sky policy to pick up and land in both cities) or Air Canada for $44 out of La Guardia or Newark is the best way to take advantage of this deal.  You still of course, have to find your way to NYC.  That's the catch of course, and the taxes are usually quite steep, as leaving out of YYZ tends to always be pricey in the tax dept.
