I believe there are many different kind of ultrasonic humidifiers for sale in Canada, so you have many other great options. For example this one is not only cheaper, but it also works well because all you need is connect an air pump hose to it . Keep in mind that if the hose is too small and long, the steam might get clogged .
The reason I used my Star Wars humidifier was because I already had it before I built the island, so I didn't want to spend money purchase another one. In order for it to work, I had to cut a aquarium vacuum hose about 6 inches long and connected to the Star Wars humidifier, then I used another smaller hose (air pump) to connect it to the bigger hose.
