What does "roving" mean? Isn't it correct under both the Customs Act and the AML-ATF Act that roving plus subsequently questioning randomly on outbound flights is not allowed without reasonable grounds?

You are not allowed to intercept everyone outbound to ask questions about anything as to possible customs or money laundering infractions can you, without probable cause to do so, or are you saying that Charter violation would be allowed?

Ironically as to this whole arrivals discussion on the whole I find the YYZ arrivals CBSA to be quite polite and there is limited questioning away from the establishment of identity. I have on occasion, refused to answer questions apart from those quoting the same manual and didn't wind up in secondary, I merely pointed out they were inappropriate , asked the purpose of the questions relative to my Charter rights, and advised that my declaration of goods (usually nothing) was accurate.

I agree reasking the $10K question to those obviously in command of English is not necessary but it happens 100% of the time.
