Transit: TTC (Toronto Transit Commission) monthly metro pass is currently $133.50 unlimited travel and transferable (share with family), 15% tax deductible ~$113.48 after tax refund (Cheaper if I subscribe to a yearly plan).
Or I buy tokens for the months with fewer working days such as November (19 days incl Remembrance Day holiday): $2.70 each or $135 for 50. (Cash is $3/ride). So 19 days * 2 trips * $2.70 = $102.6/month on the low side. October had 23 working days so 23 * 2 trips * $2.7 = $124.20. Depending on the month or outside of work travelling schedule (to see friends, shows, meetup, planned days off work etc.) I will either buy tokens or transit pass.
As an added bonus my Credit Card gets 2% cash back at grocery stores where I buy the Transit Pass/Tokens. Or I buy from Shopper's Drug Mart with their Optimum Points program (need to buy a gift card first as points are not awarded for transit tokens, but they are for for GCs... use GCs to buy transit item). I still get 1% cashback on regular purchases on my CC.
Transit stop is 5 mins from my house walking, and brings me right to the door at work. Travel time ~20mins bus ride express bus.

VS. Car (~10-15mins drive)
Toronto insurance: around $2000 for liability only, full coverage is $2400 per year average with a good record, or closer to $3000 for a young male, compact Japanese Car.
Gas $1.15 to $1.30 per Litre
Parking is $4 per day! And I still need to walk 5-10 minutes to get the front door at work from the parkign lot.

vs. Bike (~20-30mins) 7.5km each way
I'm a cycling fanatic and will ride to work in nicer weather (can't ride in the winter, Toronto suburbs is too dangerous - snow and dark = accident waiting to happen)
Cost: FREEE! (I have 4 bikes already for recreation/commuting. Approximate value of them: free, $100, $400, $2000) Maintenance and tools previously bought... it's my hobby.
Bonus: exercise! Only downside is sweat, so I'm thinking of putting the bike on the bike rack, on the bus going to work, and biking home.
