Windsor's black population is around 7000 or about 3 percent!
Detroit's black population nearly 1,000,000 or about 85 percent!!
There is no universe where these are remotely comparable!!!
****************************************************************
In 1940, Whites were 90.4% of the city's population. Since 1950 the city has seen a major shift in its population to the suburbs. In 1910, fewer than 6,000 blacks called the city home;in 1930 more than 120,000 blacks lived in Detroit. The thousands of African Americans who came to Detroit were part of the
Great Migration of the 20th century.
Detroit remains one of the most
racially segregated cities in the United States. From the
1940s to the 1970s a second wave of Blacks moved to Detroit to escape
Jim Crow laws in the south and find jobs. However, they soon found themselves excluded from white areas of the city—through
violence, laws, and
economic discrimination (e.g.,
redlining). White residents attacked black homes: breaking windows, starting fires, and exploding bombs. The pattern of segregation was later magnified by white migration to the suburbs. One of the implications of racial segregation, which correlates with class segregation, may be overall worse health for some populations.

If Detroit is one of the most racially segregated cities in America, the city, state and nation have no one to blame but themselves.
"Blacks" often faced violence and were excluded from moving into "white" areas.
Windsor did serve as one of the northern destinations of the "underground railway" prior to the Civil War - the fact remains that America is still paying the price for centuries of racial segregation!
