Updates from the two open races:
Scarborough North: It seems like the two frontrunners are Maggi Chi, an ex-assistant to Chin Lee, and Felicia Samuel, a former NDP candidate in June.
Beaches East York: The three front runners seem to be former MP Matthew Kelway, urban planner Brad Bradford, and business consultant Josh Makuch. All three were initially running in the Beaches (Ward 37) ward, which has now expanded to include East York. I give Kelway the slight advantage given that he has name recognition north of the Danforth from being MP, but the two other candidates seem to be running strong campaigns, at least down in The Beaches. According to a family member and 30+ year resident of The Beaches, the deciding issue for most of his neighbours is the vehement opposition to the Woodbine bike lanes.
