I don't live in the area, but I do work in the area and often take the 97 Yonge bus during rush hour. I find that around Yonge/Empress, traffic is always moving VERY quickly.
Your entire post makes the assumption that no one living in those condos in NYCC takes the subway, which whisks them downtown in 25 minutes.
No. I'm not assuming everyone drives! That Canada's Wonderland parking lot comparison is actually an under-estimate since most cars have 1.5 people inside but cars going to Wonderland are more likely to be full since it's family oriented. Probably better to imagine TWO Canada's Wonderland parking lots to compare the number of cars due to the new condos in NYCC.
Let's look at some hard numbers: the 60 new condo towers built in NYCC since amalgamation in 1998 have about 50,000 new residents, the vast majority are young working age folks with jobs. 30% of people in Toronto are regular transit users, in NYCC let's say 40% since it's on subway line; thus about 60% drive cars in NYCC (60% of 50,000 = 30,000). With an average of 1.5 people per car that means NYCC has to deal with 20,000 additional cars since 1998 amalgamation. What does 20,000 cars look like??? Canada's Wonderland's parking lot can only hold 10,300 cars,... so double that!

City Planning did assume everyone who moved to these condos on the subway line in NYCC would take the TTC; but that assumption have been proven wrong! City Planning also assume everyone who moves into NYCC condos would be single folks who don't have kids,... again proven wrong as we see most condo kids get bused out for school since the local schools don't have room for them.
In Toronto, about 30% of people take transit regularly. In NYCC that number is likely slightly higher since its on the Yonge Subway line. But there's many parts of Toronto on the subway line, one of the main reason people choose NYCC is because it's on the Yonge Subway line AND close to Highway 401. Since not everyone works downtown on the subway line, there is a significant amount of NYCC folks who will drive especially when they work in areas that are not transit accessible like 905.
NYCC is along Yonge corridor north of Highway 401. Anyone going south has to go south on Yonge to cross Highway 401 which acts like a huge barrier wall dividing the city. Anyone going any significant distance east or west would go south on Yonge to access Highway 401. Thus, you get a funnel effect where local NYCC traffic is funneled to the Yonge-401 interchange - result in traffic gridlock!
TTC Yonge subway line isn't better way,.... Yonge subway line is operating at full capacity. For that 25 minute southbound subway ride you referred to,.. During AM rush hour, the southbound Yonge train is basically full once it leaves Sheppard-Yonge subway station,.... and everyone is packed like sardine by the time it gets to Eglinton,... not even halfway downtown yet. Stand at Eglinton station southbound platform and see how many packed southbound trains go by before you can squeeze on. BTW, now there's the risk that ATC for Yonge line won't be completed before Eglinton Crosstown,.... so imagine a even busier Eglinton-Yonge interchange station with no ATC on Yonge line,....
LNahid2000, huh? You live at Yonge&Bloor but you take the 97 Yonge bus to Yonge and Empress during rush hour??? Why not take the Yonge Subway which would be much faster? That doesn't make sense especially since most 97 Yonge bus routes don't go north of YorkMills. The 97 Yonge bus is once every 15 minutes between Davisville and YorkMills; but outside of midtown it's once every 30 minutes - from your stops of Yonge&Bloor to Yonge&Empress it's every 30 minutes, if you miss the bus - you'll be waiting 30 mintues for the next bus - in 30 mintutes you can get from Yonge&Bloor to Yonge&Empress (NorthYorkCenter station).

BTW, whereas most TTC bus routes suffers from overcrowding due to customer demand for bus service being much higher than what the TTC can supply; the 97 Yonge bus is the complete opposite. The Yonge subway runs directly under the 97 Yonge bus route which should have been eliminated but was kept for political reasons only since too many people complained they would have to walk too far to their local subway station. Whenever you see the 97 Yonge bus, count the number of passengers you see onboard! In NYCC, there's rarely more than a handful of passengers on the 97 Yonge bus,... usually just one or two - even during rush hour!
