Comparing the 2018 route ridership stats for Finch West vs Eglinton East:
#36 (Finch West): 47,300 customers per day
#86 (Scarborough): 16,500
#116 (Morningside): 22,200
#905 (Eglinton East Express to UTSC): 9,200
#986 didn't exist in 2018
Perhaps we shouldn't include the #905 counts into the Eglinton East totals, as many of those riders travel between Kennedy and UTSC, and will switch to the subway + Ellesmere route once SSE is completed.
Adding up the #86 and #116 counts: 16,500 + 22,200 = 38,700, not that much behind #36.
Thus, if LRT is appropriate for Finch West capacity wise, it might be appropriate for Eglinton East as well.
