Check 464.500 and 464.550, those are very common UHF itinerant frequencies, and very popular with businesses.
Also, if you are transmitting very close to your scanner, you are likely overloading and desensing it, which will cause issues with the received audio. Try putting the scanner in another room and keying up. Have someone else listening and see which frequency it lands on.

Ha! My dad worked at one of the Canadian Tire stores in that area back a long time ago. He said they often wore roller skates for getting around the warehouse and pulling parts. That was probably back in the late 50's. Both my grandfathers worked for Avro there in your neck of the woods.
