It is my understanding that in the USA all toilets/drains have a clean out. I would be surprised if that were not true in Canada. It is typical to have a clean-out between the house and the public sewer connection, required in California. Usually, there is a clean-out on the outside from the kitchen sink. It is pretty easy to remove the cap/plug and use the clean-out to dump.
I have a septic tank. I park my TC in front of my garage. I ran a 2" plastic pipe from the front corner of the garage, about 50 feet to a clean-out. I installed a 25'x5/8" hose with a ball valve (3/4") on the male end of the hose. I have a hose reel on the wall to store the hose when not in use. After using the macerator, I turn off the ball valve, hold the ball valve higher than my hose and open the ball valve and drain the entire hose so it will not freeze. I then close the ball valve to prevent odors. I do have a male hose connection on the open end of the ball valve. This allows me to add more hose for visitors if needed for them to dump.
