Partly, this is due to the source used. Toronto.ca would seem the perfect source for such a quiz but it does not reflect my lived experience as a Torontonian. I have never seen neighbourhoods such as Riverdale or St. James Town divided into North and South. And where is Korea Town? Old China Town?
Secondly, the quizzer is quite inflexible with regards to acceptable answers. For example, only accepting "Yonge-Eglinton" instead of "Yonge and Eglinton" (or the even more common "Yonge and Eg").
Lastly, "Niagara" is spelled incorrectly (as "Niagra").
