Looks like MO-COAT Solutions in Calgary is the authorized distributor for the Mo-Dad system. They list the Mo-Dad product under their storage tank systems; not much detail provided, you will have to call them.

Acquired Wastewater Technologies LLC is the manufacturer of the Mo-Dad aerator system. They are located in Lousiana. At a quick glance, their site doesn't seem to list their distribution network, might be worth a call to ask them who carries their product in Canada.
You can also download the manual from their site.
