A recent and notable economic development example was the firm’s decision to become the first tenant and founding partner in True North Square, playing a role in the continued revitalization of downtown Winnipeg.

Additional Services


Sharing information in the cloud has never been easier. Recently, there has been a growing concern as to the security of information stored on public cloud services. TDS Law utilizes the ShareFile service – a secure cloud sharing platform from Citrix.
ShareFile is a secure data synchronization and sharing service utilizing bank-level encryption technology. ShareFile works like public cloud services, making shared documents available on your desktop PC or Mac, through your smart phone or through any web browser.
Benefits of ShareFile
Security – The content stored in ShareFile is encrypted both while in transit and while at rest in the cloud. That means that all interactions that you have with data through ShareFile, whether uploading or downloading files or simply accessing them through the secure online portal, use 256-bit SSL encryption. This ensures that TDS Law data is secure and prevents unauthorized physical access to our shared data, while providing users the flexibility to work with their documents as needed, using desktop, laptops, tablets, and mobile devices.
Share Large Files – Email isn’t designed to share large files, and using an FTP server to share documents is not practical either. There is no practical file size limitation on our private cloud service. Whether you are sharing a simple Word document, or an HD video of a work site, we can share it – securely.
Collaboration Simplified – Sharing documents by email creates an opportunity for multiple versions of a document to circulate, causing inconsistencies and missed updates. With our private cloud service, multiple people can work on the same document. Changes are saved automatically and updated to all authorized users.
Versioning – Sometimes updates need to be undone. With ShareFile, files are tracked, allowing authorized users access to multiple versions of a file.

Video Conferencing

TDS is committed to providing our valued clients with new services and to being progressive when it comes to adopting new technology. We are pleased to announce that TDS is now able to offer our clients video conferencing technology. In August, 2011 the firm purchased a high definition (HD) video conferencing centre to enhance our ability to serve clients in remote locations in Manitoba, in other jurisdictions in Canada and at locations around the world.
Several of our clients are located outside of Winnipeg. This new service will allow our clients and lawyers to meet face-to-face without having to leave their office, reducing time away from the office and away from family. Of course, video conferencing is not meant to replace all in-person meetings. We understand there are times when meeting face-to-face is needed, but in situations where in-person meetings are not essential, this new solution will prove to be efficient, cost-effective and convenient.
Getting started on video conferencing with TDS is easy. If your organization has an existing ISDN or Internet based video conferencing system, we should be able to connect without a problem. If your organization does not have video conferencing, there are a couple of options available to you. In most urban centres, there are video conferencing facilities that can be rented for a nominal fee, providing true HD quality video. We ask that the first time a video conference is requested with us, we do a test call in advance of the actual meeting, to ensure there are no technology issues between the systems.
Where is it available?
Our video conferencing service is available in our Winnipeg, Brandon and Portage la Prairie offices.
We support both inbound and outbound IP-based video conferencing. Our inbound IP addresses are
Winnipeg: 161.8.12
Portage la Prairie: 79.33.210
We use state of the art Cisco Telepresence equipment to connect our three offices and to any compatible IP-based or ISDN-based video conferencing system. We use high-quality 1080p video conferencing equipment to ensure crystal clear picture and sound to clients around the province, and around the world.
We support fully encrypted end-to-end video conference calls using H.235 and AES encryption to provide peace of mind, ensuring that client-solicitor privilege is protected from outside parties.
Our equipment supports the following standards
460.18, H.460.19 Firewall Traversal
261, H.263, H.263+, H.264
239 (H.323) dual stream
Please note, to conserve energy our video conference systems are in standby mode when not in use and will not accept incoming calls. Please contact us before initiating an inbound call to our systems
Clients on ISDN based systems can connect to our video conferencing system through our ISDN bridge provider. These calls must be pre-arranged.
Video Conferencing Support
