We hired Contracting Ontario for a major renovation of our place. Their crew is very professional, courteous, clean, and most importantly work fast. The work was done very professionally according to all City codes and permits. They have provided quality and clean work, were very polite in the communications. We look forward to working with CO in the near future and will definitely recommend to check out this company for any of your construction work needs or even small upgrades to your home,

Our family are very satisfied with the renovation experience that Contracting Ontario provided when we decided to add a 2-storey addition to our existing home. These guys do a great job. I like that they have a dedicated project manager for each site going. They have experienced crews that do the work quickly, professionally and clean. Their sub - trades are great as well. They were onsite everyday and the quality of work is excellent . We would not hesitate to recommend them to anyone who needs any type of renovation or repair.

I’ve been using this company as a handyman’s service since 2009. To assemble IKEA furniture, to fix leaking facet or change the sealing around sinks and bathtubs – easy, fast, not expensive. I recommended them to my friends and I do not know anybody who would complain.
