A minor change would suffice, I should think. Something like:
For all discussions relating to military activities in Canada, including the Revolts in Upper and Lower Canada of 1837, the Fenian Raids of 1866 and 1870, the Red River Expedition of 1870 and the North West Rebellion of 1885.
Needless to say, any Canadian participation in military activity outside
Canada - such as Boer War service already mentioned, or the corps of Canadian boatmen on the Nile Expedition - can be discussed on another suitable forum (.... although it would hopefully be acceptable to make a short post on the Canada forum, linking to the topic, to alert "Canadian" members who might not otherwise see it on that other forum.)
Although not contemplated in my original post, while we are at it I suggest the second change highlighted above because I think the current wording assigns too much credit/blame to Riel. The underlying grievances were widespread, and were certainly serious enough to result in the armed insurrection which ultimately occurred ..... Riel, arguably, was merely a catalyst, who was invited back to the North West Territories by the Métis
to espouse their cause, and who initially urged further peaceable communications with Ottawa as the best means of addressing the issues. (By the same token, I would certainly oppose calling it the "North West Resistance
", as too many have begun to call it of late!
