Zenic comes a 10 minute early at 8:50 am, so that is good.
My attic has 10 year old R30 (~ 10" height), ~850 sq ft. I only called for 2 quotes. One from Kijiji for $700, and another is Zenic $800. I chosen Zenic due to near 10 star rating.
He done a quick inspection and found everything good in my attic, so I'm not replacing any baffle, although that is free.
The job is quick, clean, good. 2 person came, and Zenic is doing the work himself. No complain
My gas (95% eff furnace) used to be $130/month in winter. Let's see how much it will be for this winter.
Giving him 10 stars in this review.
Next project will be replacing my double-layer single pane windows

Update 2015-09-09
Comparing the cost saving after 1 winter and summer. There is near $0 net saving included the annual utility adjustment (inflation) for both gas and hydro electric combine.
I am comparing Dec - Apr 2013 to 2015 for winter
However, the upstair feel warmer in winter and don't need extra clothing. The furnace can warm it up sufficient enough while still keeping 38 yr old double sliding glass windows (no glass insulation).
For 2015 summer, upstair still can't cool down at all with 30 C outdoor. It only maintain at 25 C, while main floor is 20 C. It is better than before doing the attic insulation topup.
Certainly looking into replacing all windows, but not saving any money to spend in this project
