Yes, but in a roundabout way. I crossed the country west to east on the Nothern Tier. We went through Niagara Falls, ON on the way to Maine. I then rode home to Philly. Not exactly what you looking for.
One way to go is up to the Canalway from Albany to Lockport and enter Canada near there:

BTW...You don't have to go to north Jersey to find hills. Hunterdon & Warren Counties in west central NJ have plenty of them. In fact, some of the hardest climbs in the state are there. But if you will be in far northwest Jersey, make sure you do the climb to Highpoint State Park.
If you wan't a nice, three-day shakedown trip, consider Port Jervis, NY to Philly. I can give you the route. Avis has one-way rentals to Port Jervis. You can also get there via SEPTA to Trenton, NJT to Seacaucus Jct. and then the Metro service to Port Jervis that is also run by NJT. The ride through the Delaware Water Gap National Recreation Are is very, very pretty. So is most of the way down the river from Delaware Water Gap, PA.
Somewhere at home I should have the cue sheet from one of the longer routes of the Black Bear Century out of DWG, PA. That makes a nice day ride in that area. You could camp at Worthington State Forest and do some or all of it. The route goes right past the campground.
