I get amused to hear about how backwards Americans think Canada is. When we started a tech company six years ago, I couldn’t believe how archaic the internet was in the US. We couldn’t operate in the US because not enough users had high speed internet to be able to use our product. I assumed that everyone had fast internet like 90% of the population had access to in Canada for five years prior to that.
Things today are now similar in both countries. Most people have high speed access today. I understand that free wifi is available in most cities in the US now like Canada has had for many years.
As for online shopping in Canada and online use, Canada leads the world in internet usage:

Most Canadians order from Canadian companies so that might be why you didn’t get many orders from Canadians.
As per the customs and duty charges, if you are selling on amazon.ca to a domestic market, the seller is responsible for all customs, duty, and brokerage charges. I can’t find the section that shows this but I assume it would be similar to someone in the US ordering domestically on .com.
But you’re right: It’s best not to bother selling to Canadians. Leave it to Canadian companies.
