And like a bad penny he keeps turning up with new information. I have been trying to ascertain a way to keep from cutting a hole in my newly restored deck for a pumpout fitting and still meet the criteria for voyages to Canada. Upon reading an extensive list of regulations I threw up my hands and went right to the source. I contacted a representative of Transport Canada for clarification. To meets their requirements for 'porta potties' what is necessary is that it be secured to the boat as to render it immovable. It may be secured by a latching mechanism that allows for transport to a shore side waste disposal facility. My personal choice for YOT is the Thetford 365 unit and hold down kit. This was also the response I received from a representative of Thetford Corporation.
