Canwood was a House of Tools house brand. They are unfortuneately now out of business. Bob is correct in that they did not sell Taiwanese junk. It was somewhere in between and usually the price/quality issue was a reasonably good deal. I bought some of their router bits and a milling machine and have had good service from both.
Just for an example, I bought a King Canada 16" planer a few years back. A cousin bought a Delta 15". They are identical in 99.9% of all aspects. I have also seen other name brand planers that also appear to be identical. The Canwood is likely no different. House of Tools did not have a manufacturing division. Like Sears, Canadian Tire, and other retailers, they paid to get their name put on some Taiwanese manufacturers machine.
I bought a Makita 1900B 3 1/8" motorized hand planer a number of years ago. I recently found out that Hitachi also had a 1900B that was identical except for color which tells me that they weren't Makita or Hitachi but some Taiwanese brand instead.
The jointer you are looking at is the same. There were probably many brand names of the same one. Blades are the easiest thing to match up.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
