Catharine E. Williams Professional Corporation
111 Waterloo Street, Unit 211
London ON N6B 2M4

We are located on Waterloo Street, south of downtown.

Please note that Waterloo Street ends at York Street and resumes at Horton Street due to the train tracks so you must access our area from Wellington Road or Colborne Street.

There is a parking lot beside our building.
The parking booth is presently unstaffed so parking is free.
If there are no spots available on the main or upper levels, there are 3 underground levels as well.
