Yesterday, I saw two guys riding this funny scooter boards in the park. They told me it is called “iNoWalk”and is available in Canada via online store https://inowalk.ca/now. I ride it for a few minutes and found the riding is quite interesting with lot of fun, but might be a little bit too expensive for a fun toy.
They gave me a business card and told me that they are starting take online pre-order and offer special deal now for only CA$1150 (list price is US$1800). You may want to check their website if you are interested.
