Albie said:OK, here is my thinking. Clydesdale is a Scottish name, so it is most likely that a Scot would have named a breed of horse Clydesdale. If this were the case and if the predominant settler in Ontario was the Scots, then that would possibly be the reason for favouring this horse. As for the Alberta et al, could this be the French settlers?
Bit of a guess, but worth a shot.
Close enough, Albie! Clydesdales are great work horses, and are from Scotland. Many of Ontario's early settlers came from Scotland, and thus brought their favourite horses. They kept on with them because the big beasts were great for hauling timber in the thousands of lumber camps in the colony.
Percherons were popular in Alberta because they are better suited to farm work and swift riding. The horses came originally from France, but most of Alberta's first settlers were from Eastern Europe and England (they brought the breeding stock with them).
It was tough and obscure, but you got it fairly well!
