Another city with strong Irish heritage is Ottawa and the surrounding Ottawa Valley region. The city was roughly 25% French Canadian and 25% Irish Catholic for the 19th century until after WWII. Of course it's become more diverse given the growth of the national capital and growth from immigration.
In the surrounding rural region Ottawa Valley English was Irish-influenced. Immigration occurred in both the pre-Famine and Famine years.
