Anyone in the Great Lakes area familiar with the procedures for overflying
Canadian airspace? Specifically from the Detroit area to Niagara Falls, NY.
Is there a fee if you don't land in Canada?

Yes. If you use NavCanada services (and you must) the owner of your plane
will be billed $15 for 4 months service. If you come back any time within
that 4 months, you won't be billed.

Do you still have to file a
DVFR flight plan?

You've never had to file DVFR - that's only for penetrating the ADIZ off
the coast. You need to be on a regular VFR flight plan, and you must be
talking to somebody (getting flight following) as you cross the border.

I can't believe you'd have to go through customs once in
NY, right?

No, you don't have to go through customs if you didn't land in Canada.

I'd prefer to land in St. Catherines, ON , but I thought I read somewhere
that on entering Canada you have to land at first INTL airport, and I'm

No, you land at any Airport of Entry. On a flight from Rochester to
London Ontario, I passed over any number of international airports (St
Catherines, Hamilton, etc) and didn't land at any of them. Same on the
way back - didn't land at Buffalo even though I flew right over it,
cleared customs at Rochester.

assuming on return to the US I'd have to go through Niagara Falls anyway,
pay some landing/parking fee's and then play with customs, so not worth it
probably.

If you land in Canada and come back, you'll need a US customs sticker on
your plane. If you don't have one ahead of time, you'll need to be
carrying $50 US on your person to buy one - they don't take checks, credit
cards or Canadian money.
