That happened to me yesterday when shopping along St. Clair West on my way to work.
This is a Thermos Bottle Co Ltd made in Toronto Canada (so it's etched on the bottom). It also reads "Thermos Stronglas, registered trademark, Made in Canada."

It's glass lined and has a hinged top and I just love it.
The thermos technology was created by a Brit but sold to various companies. The Thermos brand has a fascinating history; check it out if you're so inclined.
I think it was $6.99 when I was there the first time, but the price tag had fallen off so the powers that be at the Salvation Army Thrift Store gave it to me for $2.99.
I call that thrifting karma.
