That sounds about right.
If you look at the net immigration flow between Canada and the US, the trend is pretty clear.
US immigrants of Canadian origin (2019): 11,900 [1]
Canadian immigrants of US origin (2019): 10,800 [2]
Of course, with 8.7x the population of Canada, you'd expect the net neutral number to 1:8.7 (Canada to US), but it's actually 1:1. So ~9x more Canadians per capita immigrate to the US than reverse.
