I don't know if anyone has produced a map of the southern Ontario ridings, comparing 2015 to 2019, but here is the overall standing. The Liberals and the NDP lost and the Cons and the Bloc gained. There is a large immigrant base in and around Toronto. I'll leave it to the pundits to dissect how the vote went there.
Liberal was 177, now 157 - loss of 20 seats
Conservative was 95, now 121 - gain of 26 seats
Bloc was 10, now 32 - gain of 22
NDP was 39, now 24 - loss of 15
Green was 2, now 3 - gain of 1
Others was 9, now 1 - loss of 8
Looks like Canada is going in the right direction anyway. It took us the 2010, 2012, 2014 and then the 2016 to gain control, and what do the conservatives do? they spent their time fighting of course.
