I would stay at Milton Heights Campground in Milton Ontario just west of Toronto close to the 401. A very nice well managed park. Take the Guelph Line exit and go north and then take the first right and run along that for maybe 3 km and you will see the campground on your right. Entrance on Tremaine Road.

Also I totally disagree on avoiding the 407, it is wonderful and we use it whenever crossing Toronto or even going into Toronto. We always take the TT on the 407. It misses the Toronto zoo, gridlock and is a pleasure to drive. Totally bypasses Toronto with very few large trucks. It ends at Brock Road and just take that south to get back on the 401. You will not regret taking it. Well worth the toll.

You will not get into Rockwood or Darlington in July unless you get really lucky making a reservation 6 months ahead and you have already missed that window.

Don't get me wrong I take the 407 whenever I can and I prefer it, but I grew up in the area. I am thinking from the perspective of someone who has never visited the Toronto area. It is a highway that will cost about $40 to cross Toronto with 2 additional axels (one of the highest tolls per mile I have ever come across anywhere in North America). That could be a bit of sticker shock. Also for someone not familiar, having a highway just end in the middle of nowhere (and the 407 & Brock Rd looks like the middle of nowhere if you have never been there) could be confusing (even though it really isn't). There have been too many times when my GPS knew exactly where it was going but I was sweating thinking I was lost.
I think what both our comments point out:
407 = quicker and expensive
401 = more direct and more traffic
