I opened my shop in Nov 2012, and committed to ship to Canada from the get-go.
Here are my reasons why.
First, In the early 1990's on a mineral buying trip to the Tucson shows, I befriended a young Canadian couple who lived in Banff and made jewelry. They sowed the seed for me about online retailing. Given their inland location in the Canadian Rockies, online selling was a necessity for them. At the time, I owned a brick and mortar store and put off online selling until my Etsy adventure. I am still grateful to them for their example and encouragement.
Second, as a bead supplier, I was encouraged by my mentor/Etsy store owner to sell to Canada because her customers had shared that bead shops don't exist in many areas of Canada. So, it was an easy win-win for me to include Canada.
Finally, I have lived in the US close to Canada in several different states, and have warm feelings toward our northern neighbors. There are so many ways our lives and politics intersect. As an environmentalist and bee steward (aka bee keeper) there are many, many issues which I follow, that also impact Canadians to the north.
Christina, thanks for asking!
