I'll be traveling to Toronto this week in couple of days. I will spend most of my sightseeing time near the Harbourfront area and such, but I live in Scarborough.

I just wonder if anyone has any general advice about commuting in Toronto. Also, is it practical to take bikes onto TTC bus/subway? What to watch for if I do take bikes onto public transits.

Also, if there are any rides that are great for sightseeing please let me know as well.

Thanks
