Make a deal with Britain, and you and South Africa will immediately be cranked up to Tier III.
I've already been talking with MagnificentOne regarding further autonomy. It's a natural goal—every leader of every British white settler colony was clambering for autonomy around this time. Like I said, though, the colonial status of Canada doesn't hamper its governments ability to operate as effectively as any other nation of similar economic stature and industrial and infrastructural development. A lack of control over foreign affairs doesn't affect anything
but foreign affairs, especially in Canada's case.
With that said, the stats say that Canada has its own military? The British Army and Navy are still in Canada at this point. It wasn't until 1906 IRL that the British forces left their HQ in Halifax and Canada formed its own military force, unifying all of the various regional militias and constructing/organizing the Royal Canadian Navy. You're giving Canada too much military control and not economic/domestic control to fit the timeline.
