Welcome to the wonderful world of fishing!
I'm pretty sure I live close to you, I'm also in East York.
I've been fishing for several years and I can tell you that Toronto has some great opportunities.
A great place to start imo would be Grenadier pond. It has always produced for me even after the die-off in August of 2013. (Went back in September and caught a 3lb Largemouth which looked very healthy)
Have not been back in 2014, but will venture out there again shortly =)
Panfish where the hardest hit by the die-off, but my guess is if you dont care what you catch, you'll have a great chance in hooking into atleast some bullheads. *WATCH OUT FOR THE SPIKES!*
Try this, go to a store that sells tackle, (Canadian tire, or a Walmart) and look for some size 9 or 10 hooks, (the very small hooks) then, look into purchasing a small tub of a product called "Gulp Alive waxies, or the 1" minnows" -their expensive, at around $7.99 a tub, but imo a much better investment then worms. (You can always put them back in the container and re-use them)
I have literally caught fish every single cast there last year using the white waxies. (Lets call it 8/10 casts, just so I dont seem smug ) They seem to attract the fish at Grenadier pond. Everything from crappies, bluegill, bull heads, yellow perch and sunfish.
Use a split shot about 12" away from the hook and a bobber about 20" away (It gets very weedy there) and place 2 or three of those white waxies onto your hook and prepare to be amazed! Truly a great artificial bait, its never disappointed me.
Hope this helps =)
