About 15 years ago another fella from England posted here that he was travelling to Peterborough and wondered if anyone in the area would like to hook up for some fishing. I had a place nearby and invited him up when he got here and we had a great day fishing together and became very good friends after that. We kept in touch for a long time that but sadly he's never come back to Canada.
I still live just 15 miles or so north of Peterborough but no longer fish but there's lots of other guys in the area who I'm sure can help you out.
Best of luck when you get here, it's a beautiful part of Ontario.
