Lakeside Communities commutable to Toronto

My mother retired in Orillia over 2 decades ago and the city has been really kind to her. It's nestled wonderfully between Lake Couchiching and Lake Simcoe, with miles and miles of waterfront beauty.

Most of my relatives are originally from PEI and New Brunswick, and many live in the Burlington Hamilton region, with Branford being a fave locale. This means that Lake Erie is a prime cottage area, and it has been since I was a kid. My cousin Brian and his wife just bought a Lake Erie cottage in Featherstone, not far from Peacock Point.

This got me thinking; Which lake communities within an hour or so of Toronto are the best? There are little lakes very close (Musselmans, Wilcox, Bond, Preston, Chalk etc), but properties rarely change hands on these, and prices are often high.

The choice seems to be among:

Killarney Bay of Lake Simcoe, north of Newmarket

Lake Scugog, east of Uxbridge, north of Whitby

Anybody know any other cool lake areas not far from the Big Smoke? I'd say there are dozens within 2 hours and hundreds within 3 hours, but let's keep the search down to 90 minutes or so. Sutton / Pefferlaw would be about the northern limit, with perhaps Orr Lake and the Midland, Wasaga and Collingwood areas being the northwest limit, and Lake Scugog / Port Perry area being the northeastern limit.

Any towns on these lakes or nearby to them we should know about?

Peace 2 All,

Joe
