My experience with Regus at the beginning was a rough start, however I’m glad I stayed with it. Initially, I was coming in a few days a week to rent a space for a few hrs. Now, as a practice owner I can call this place my own. Blanca, has been tremendous at helping me with this journey and very accommodating when needed. She was there to hear me out and found every solution to make things work. Anthony, always go over and beyond to help with anything that I need and had been generous since day one. I appreciate all that Regus has done for me and the respect that they provide. The location near the water is what I needed to get through my day, and the environment is so serene. Thank you!

Never leave your card info with them! Them or their system will try to wipe your card out, Then they will reply with “we will help you out within the next business days” on a business day. Zero trust

Frequently Asked Questions

  • Adaptability is at the core of coworking, so membership options are always designed to cater to your changing work requirements and team dynamics. Most spaces offer month-to-month memberships, enabling you to adjust your workspace to your changing needs. Whether your business is growing or downsizing – or you just want to upgrade to a more private setting – you always have the flexibility to make the changes you need.

    While your membership agreement may have specific terms regarding changes, don’t hesitate to reach out to Regus to discuss accommodating your adjustments.

  • Most coworking space amenities are open to all members, regardless of the membership plan. Meeting rooms require prior reservation, and private offices are exclusively available to those with subscription packages. However, the lounge, kitchen, and breakout spaces are open to everyone. Complimentary amenities are also available to all, while ancillary services can be purchased or negotiated individually with Regus.

  • Regus - Ontario - Waterside Center operates during regular business hours, as indicated above. For access outside of these hours, please contact the operator directly to inquire about any available options.

  • Coworking spaces typically have limited storage options, most of which are reserved for members with dedicated desks or private offices. With that said, it’s best to contact the coworking operator directly via the form on the right side of the page to learn about available storage options.

  • For spontaneous collaboration and interaction, open desks provide an open and flexible environment. If you prefer a dedicated space with shared community elements, dedicated desks offer a great balance between personal space and interaction.

    On the other hand, private offices are best suited for focused work and private interactions. They're ideal for solo workers as well as teams seeking a dedicated space, shielded from distractions.

    Choosing the ideal coworking arrangement for you is about aligning your workspace with your work style, team dynamics, and project requirements.
