Gonch Multi-Cache

The Uniquely Canadian Series highlights words that only Canadians know and understand.

A gonch is a slang word which has similarly sounding synonyms such as gitch, gotch, gooch, and ginch. It means underwear, underpants, briefs, boxers, or whatever other word you can come up with.

This is a multi-stage cache. The cache is not at the listed coordinates, but this would be a great place to park. Across the street there is a scientific building belonging to Western University. The name of the building can be matched to digits, starting with 0. Then you can calculate the final coordinates by decoding the following:

O,E1   L1,I   E1,E2,I   T,D,H   T,I   O,L2,L2
