As I recall,  Canada has had a woman Prime Minister - albeit for a shot period. Canada has also has women for Premiers, Mayors, etc as has the United States. 
As for women who become pregnant and single mothers, pray tell what their fate is in Muslim countries? It occurs to me that one of the best ways for a Muslim man to have a woman's life ended miserably is it impregnate her against her familly's wishes. 
Contrary to your perceptions, the US provides free schools, scholarships, and medical assistance to the underprivileged. 
North America is  more prosperous, more civilized and far less riven by non-secular influence than any of the places you have mentioned. 
Bottom line: neither Canadians or Americans are emmigrating or seeking refugee status in Muslim countries for a better life or for relief from oppression.
