This is the Anglican Church of the Holy Trinity in Toronto, Ontario. It was built in 1847, and is located in what is now the very downtown heart of Toronto.
I admit I'm pushing the geographic nature of this blog with this one (not for the first time), as Toronto wouldn't normally be considered "the west", but perhaps its not quite as farfetched as it might seem. While Toronto is a huge major North American city today, all Canadian cities in this region and further west were, at one time, part of the Canadian frontier, a frontier that lasted longer in some respects than the frontier in the United States did, even though the history of the Canadian West and the American West are part and parcel of each other.
This is an Anglican church,. and at one time Toronto was a very English town.
