I will be flying through the Toronto airspace from the southwest,
landing at Buttonville (CYKZ). It would most likely be IFR. I realize
I have to detour around Pearson (CYYZ) to the north or south. I don't
know if there are standard fixes that ATC assigns for aircraft
transitioning the airspace. My preference was to plan a southerly
route along the lake shore because it is more scenic. But the class B
shelf looks pretty low over the lake, and I don't want to end up being
vectored too far over water. I would like to hear from anyone who has
flow this route. Thanks!

I've flown into Buttonville VFR by following the lakeshore route.
Depending on the direction of your approach into Toronto, this may be
shorter than going around Pearson to the west. Once you've contacted
Toronto ATC, they will vector you as needed. As was mentioned, you would
probably wind up talking to City Center as you approach their airspace,
but that's not a problem. On one of my trips, I was further over water
than glide distance, should the engine suffer a major failure, but I
didn't see that as an unreasonable risk because there wasn't any better
place on the shore to put down anyway.
