I love the name. For me, "Toronto Metropolitan" evokes distant memories of riding the GO train into the city when I was a kid, and seeing the Metropolitan Toronto logo appear in those funny grass advertising spaces next to Lakeshore/the Gardiner.
Obviously it's nostalgia, but the name reminds me of a happy, simple time in the city. I also think "Metropolitan" sounds really Greek, cosmopolitan, and like a tasty ice cream flavour.
I never much liked the sound of "Ryerson", it sounds like rye bread, which is good too, but sort of bland and dry compared to delicious Metropolitan ice cream.
