What is the Warranty in Canada for LZW30 & LZW30-SN (On/Off Switches)?

I don’t really see any information on the site for warranty, nor any warranty policy - particularly for people that buy it in Canada via Amazon.ca

Basically, my question is

  1. What is the warranty period for Canadian buyers?

  2. If, in the unfortunate even a warranty claim is needed, what’s the overall process?
