Trusted Condominium Management Service in Sarnia, Ontario
Sapphire was built to raise the standard — because too many boards were feeling unheard, unsupported, and stuck with unresponsive managers.
We believe condo boards deserve a management partner who communicates clearly, follows through, and makes their life easier, not harder.
Our Approach
We started Sapphire after seeing too many buildings, and too many people suffer under mediocre management.
Phones went unanswered. Emails sat ignored. Vendors weren’t followed up with. Owners were left in the dark.
And in the end, the board was left holding the bag.
We knew it could be better, so we built Sapphire to be the company we wished existed. At the heart of what we do are three core values:
Approachable — so no one hesitates to reach out for help
Reliable — so what we say actually gets done
Responsive — so people get answers when they need them
These aren’t just words. We’ve structured our entire operation around them.
By combining the right technology with dedicated operational experts, we bring innovation to a slow-moving industry — not for the sake of tech, but to make great service feel effortless.
We use tools like UpperBee that keep communication clear, systems that ensure follow-through, and processes that bring clarity to even the most complex buildings.
Because when management is working the way it should, you feel it — in your meetings, in your inbox, and in your building.

I Would Recommend Sapphire
From Marg Emergy, President—Corunna, Ontario “Corunna Riverside Condominium”
“We have worked with Denise for the past three years. Denise’s professional manner gives you comfort level from when you first meet. She is down to earth and calm in many situations that find Board members stressing.
She has always responds to our concerns by phone or emails in a timely manner. Although Denise handles many properties at the same time she gives us her full attention to us and makes us feel like we are her only and most important client when we need her help.
Her experience, understanding and familiarity with the Condo Corporations Act is her strength which gives us a confidence no matter what the issue. As a condo board member for six years and President of the Board for four of those years I can honestly say that Denise is the best property manager I have worked with.
I would highly recommend Denise McAsey and her company Sapphire Condominium Management as my first and only choice as property managers.”
