I have a former boomer coworker who sold his house in the east end and just retired in Peterborough. Originally, he wanted to retire in Guelph or Elora, but he said he got a much better bang for his buck east of the city.
Former co-worker or former boomer (how does that work?)
A brother-in-law moved from the city (St. Clair/O'Conner-ish) to just outside of Cambellford. He has a post-retirement (ok, forced downsized) gig which he mostly do online with the odd trip into the city via train.
The bang for the buck depends on where you go. Although anyplace will be cheaper than the city, Prince Edward County has been 'found' and is much pricier that it used to be. As a general statement, I think anything north of the 401 would be cheaper.
