Good day folks. I had the opportunity of travelling through North Bay, then to Petawawa via Highway 17 to Ottawa last weekend. I was amazed to hear pilots contacting the local mandatory/advisory freq. Plus, I noticed Montreal manning the Ottawa TCU sectors. In Ottawa, I noticed the same voice on the french ATIS. I assume this is a recorded voice upon metar updates, similar to an AWOS. I still can't get the english ATIS. Nonetheless, I am surprised that off-peak periods in the Petawawa sector, the controller there monitored 3 freq's just like the guys up here look after 4 freq's in 2 sectors. It still amazes me how much work these guys can handle.
