I called and clarified with the Aylmer Office, I spoke to one of the guys that helps make the decisions for the regulations and he clarified with others and the CO's. The fish sanctuary only applies to the Thames river between the dam at the Gordon Pittock Reservoir and the bridge at Highway 59. He said the wording was definitely not clear and was incorrect. We can still fish the Main Thames as usual for species that are in season.
TLDR; FISH AS USUAL IN THE ENTIRE THAMES RIVER, FOLLOWING WHAT IS IN SEASON, EXCEPT FOR THE FISH SANCTUARY I MENTIONED ABOVE.
Now I'm going to go try for some catfish tonight
