First, we are trying to put the health and well-being of you, your family and our staff as our top priority. We remain fully staffed and committed to serving your needs as best as possible to assist you through this challenging time.

Our systems allow us to work as effectively remotely as we do in the office, keeping disruptions minimized.


Mississauga Office

Our Mississauga office remains operational with some staff working in the office and others working from home to enable us to provide service you can count on with minimal disruption. Due to the highly contagious nature of the COVID-19 virus, we are asking that those who choose to stop by the office to drop off information use the drop-off box in the front vestibule of our office and not step into the reception area if it is not necessary. We are also deploying enhanced cleaning protocols for the office, especially on frequently touched surfaces.

Although we are not having in-person meetings with clients at this time, we remain available via e-mail, phone and conference call.

Burlington Office

Our Burlington office, consistent with the recommendations made under the state of emergency declared for the City of Burlington, is closed and all staff members are working remotely, responding to phone calls and emails. The office has mail slots in all doors where information can be dropped off. Wherever possible, we encourage you to send your documents electronically if possible.
