RE: Insiders selling?data is garbled. scan further down the paper to Stantec Inc. The rest of the data for Challis activities is located there and has nothing to do with Stantec. His last transaction is 100, 000 option at 0.50. I would say their are some issues with the mixed up data on the alberta securities site, how would Shore data be mixed in with Stantec's. Excellent job alberta securities commission. not.
