The Linotype Company of Montreal, Canada manufactured some Oliver Nos. 2 and 3 for sale in Canada and South America. The Linotype company also referred to themselves as the Canadian Oliver Typewriter Company. Robert Messenger has a great article about the Canadian Olivers on ozTypewriter.
There are several features that could identify a Canadian Oliver from afar. Some machines have the ribbon spools mounted vertically instead of horizontally. The Canadian Oliver No. 3 has different side panels with "Oliver" displayed with bold letters. The Canadian No. 3 paper tables display "The Canadian Oliver Typewriter - Montreal".
The Canadian Olivers have their own serial number scheme. It is unknown how many were made or where the serial numbers begin. Only one Canadian Oliver No. 2 machine is known to exist and only four Canadian Oliver No. 3 machines are known to exist.
