Whakaotihia te rerenga e whai ake nei: I heke atu ia me tōna whānau ki Upper Canada i te tau 1834. I āwhina a Irving ki te whakamutu i te
Upper Canada Rebellion, e mahi ana i te rohe o Niagara. I noho ia ki Newmarket, a, i tohua ia ki te Kaunihera Ture o Upper Canada mai i te 1843 tae noa ki tona matenga. I riro hoki a Irving hei kaitiaki tuatahi mo te rohe o Simcoe i te tau 1843.
