I bought an convertor box from ebay for my daughter in Toronto at Front Street last year.

Wiith an amplified rabbit ear we are able to pick up about 20 digital stations including those across the lake.

That convertor does not have an anlog bypass, at first I left her a switch in case she wants her analog channels back. However I took the switch off the next visit since I didn't see her switching back once we tasted digital channels.

We only have 6 DTV OTA in Ottawa without using an outdoor antenna, but you may get a lot more in Toronto.
