There are more companies dealing with these products in Canada now, anyone has experience with www.3dome.ca or www.albixoncanada.ca?

Yes
there are products sold by companies out there, but not similar. They are designed for light snow , wind and
can collapse if snow is not removed or must be taken down in
high winds. Please read their warranty.

An excerpt from their Warranty

"Our warranty is no
longer valid in wind over the insurance limit (15 m/sec.)" which works out
to 54km/hr or 33.6 mph. And "There
is no warranty applicable for the enclosure if it is not protected from the
accumulated weight of snow. Pool
enclosures must be immediately protected from snow and ice that must be
immediately removed." See our blog on a collapsed enclosure http://www.coversinplay.com/blog/collapsible-enclosures-even-when-you-dont-want-it-to-be/

We recommend do your homework
before purchasing an enclosure no matter where you live.
