Stick to fighting fires I say, I'll bet no ATC will write to the Prof Firefighters Rumour network asking how you fought your last fire.
Very harsh.
Ottawa at no time says "it looked dangerous" or "ATC were in the wrong". He merely asks a genuine question to try and find out the procedure so give him a break.

Its very probably different in canada, but at heathrow its possible to issue an "after the departing, cleared to land" clearance which makes assumptions (hence we're still responsible for providing separation) that when the landing aircraft crosses the threshold, the departing will either still be on the runway and at least 2500m along, or airborne and at least 2000m along the runway. Thats the rules for the types of aircraft you described. There are different rules for propellor aircraft, and there are also weather criteria which have to be achieved also.
As I say though, it may be different in canada.
Hope that helps.
