One thing that stood out to me is that immigration from Canada nearly stopped altogether in the mid 1890s. I wonder if the klondike gold rush was a factor here. I know it spurred a mass migration to the North.

As a collateral effect, even Vancouver's population skyrocketed growing from around 13,700 in 1891 to over 100,000 in 1911.

Probably one major factor was completion of the trans-canada rail road to British Columbia, finished in 1885 by CPR. This allowed free movement of immigrants from Coast to Coast, lowering immigration to the US and moving that migration to Western Canada.
