The Canadian dollar is currently worth about 75 cents US, down roughly 25% from 2012 and 2013 when it ranged between 95 cents and $1.03. This makes homes in Arizona much more expensive than they were a few years ago, if you are converting funds to or from Canadian currency. In the first 9 months of 2016 we have seen an exodus of Canadian-based homeowners with 1,736 selling up and only 333 purchasing within Maricopa County, a net loss of 1,403 homeowners.
In the same 9 months of 2015 we saw a net loss of 679 (1,323 sales and 644 purchases) and in 2014 we saw a gain of 250 (820 sales and 1,070 purchases).
The boom years of 2012, 2013 and 2014 gave us net gains of 3,327, 2,572 and 986 respectively, so the current exit rate is less than half the arrival rate of 2012.
I do not know if we have reached the peak Canadian exit rate, but we are currently losing about 7% of home-owning Canadians per year, something we have never seen before.
