Mr. Speaker, before leaving, the two parliamentary secretaries proactively contacted the Ethics Commissioner, who approved the trips. What is more, they submitted the appropriate public declarations upon their return. It is not unusual for parliamentary secretaries to go on these sorts of trips.
Just ask the House Leader of the Official Opposition, who agreed to go on a trip like this to London, England, in July 2011 when she was the parliamentary secretary for the Department of Public Safety.
