I recently used Ranstad Ontario to apply for work. I had help from Delmy Corrales, she was very helpful and positive. She got back to me right away about an available position and was in contact with me every step of the way, up till my hire date. Would recommend if you are in need of work. I read some of the other reviews and I cannot relate to the negative ones. They saw my resume and work experience and I felt they helped match my experience to a company that’s a good fit for both myself and the employer.

You apply for jobs on the app and no one ever gets back to you. They make you perform tasks for a job you do not have and do not pay you for it. Training for the job should only take place if the person is being paid

Practically impossible to get a hold of anyone here. So unprofessional to not even answer your phones. No one ever replies, and when you do apply online, you never get the info on drug test/next steps. This place is a ghost town, do people even work here?

Wish I would have read the reviews for this company first. They do not answer the phone or messages through the app. Absolutely frustrating and unprofessional!

I have tried contacting multiple people at this agency by phone and text, yet I rarely receive a response. When I have managed to get someone on the phone, I was told to use the app and show interest in the jobs that are posted. I have done exactly that several times, but weeks go by without a single text, call, or follow-up. It has now been over a month, and I still have yet to receive any response. Eventually, the job posting just disappears, and the same cycle repeats over and over. To make matters worse, even when you comment and they give you a phone number that the agency provides in the comment section of the job posting, it does not help whatsoever. There is still no response, no follow-up, and no communication. This has become extremely frustrating and exhausting. It’s honestly hard to understand how this agency continues to operate with such poor communication and lack of follow-through. This level of unprofessionalism is exactly why people struggle to take staffing agencies seriously. If you expect people to take the opportunities you provide seriously, then your agency should also take its responsibility to communicate with applicants seriously. If you’re looking for a solid job or a staffing agency that is actually persistent and communicates with its applicants, I would strongly recommend looking elsewhere. Save yourself the time, the energy, and the frustration. Based on my experience, this agency has consistently failed to communicate or follow through. 🙄🙄

Frequently Asked Questions

  • 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.

  • Absolutely. Flexibility is one of the best parts of coworking. Most coworking memberships are month-to-month, so you can quickly adjust your space preferences according to your unique requirements and the size of your team. Whether that means upgrading the space or downsizing it or even completely changing the type of coworking subscription that you use, you always have the option to adjust as you go.

    It may be possible to adjust your membership before current membership ends, but you will have to discuss and negotiate directly with HQ, who is more than happy to help out.

  • Whether you're a day pass holder or a monthly member, you can access most amenities. Meeting rooms do require prior scheduling, and private offices are reserved for those with subscriptions.

Complimentary services are also available regardless of membership tier, while ancillary services can be purchased separately or negotiated with HQ.
