Ok, I extracted the source text from both the Tim Hortons OV2 files, and merged them together, and sorted by Longitude.
The entries with the postal codes are those from
GPS-Data site, which is believe is newer and contains more entries. The entries without the postal codes, are from this site.
Here is a link to the combined file, in plain text mode.
As you can see, there are some obvious discrepencies. I was going to remove the dups, but upon closer inspection, you can see the longitude and latitude coords do not match from one file to the other... which is right? Who knows! Does it matter at that minute level? Maybe to some people.
