Relationship and Couples Counselling

HealthOne’s therapists provide relationship and couples counselling to support any issues you are experiencing with your partner. 

There are many areas of concern that can be addressed during these counselling sessions, including but not limited to communication issues, trust, relationship anxiety, intimacy, major life transitions, parenting, and grief. 

Our therapists focus on providing a person-centered counselling experience. They will help you and your partner improve your communication, interpersonal effectiveness, and emotional regulation while building on critical core values such as trust, respect, compassion, acceptance, validation, and understanding.  

Having a non-biased professional initiate and facilitate conversations around the issues you are experiencing can lead to an improved connection with your partner.

Anxiety Counselling

At HealthOne, we understand that everyone’s experience with anxiety is unique to them. Our therapists will work to understand your specific needs and provide counselling to address and support your challenges.

Anxiety is one of the most common mental health concerns experienced by individuals in North America. It is defined as a complex emotional state that occurs when you anticipate a future situation that may involve a personally distressing, unpredictable, and uncontrollable threat to your well-being. Common symptoms people may experience include always feeling tense or worried, thoughts that interfere with daily life, having irrational fears that cause distress, avoiding certain experiences that are known to trigger anxiety and panic attacks.  

Anxiety is a common reason why individuals go to therapy. Our therapists consider and aim to understand your unique needs so they can provide you with an individualized counselling approach. We invite you to book a complimentary “Meet & Greet” appointment with one of our therapists to discuss whether our services are a suitable fit to help treat your anxiety.  

Our therapists specialize in providing Anxiety Counselling.

Meet and Greet

At HealthOnebooking a Meet & Greet appointment is the first step of your counselling experience. This allows you to meet the therapist either virtually or on-site and determine if they would be a good fit for you and your unique needs. 

During this brief session, you can learn more about the practitioner’s individual style and approach to counselling, which varies from one clinician to the other. You can also ask any questions you have about their approach before booking an initial consultation. 

You can book a Meet & Greet appointment with more than one therapist if you wish to meet multiple members of our Mental Health team.

Frequently Asked Questions

Can therapy really help?

Working with a good therapist can improve your life in many ways. They can help you cope with difficult feelings, learn problemsolving skills, and change the patterns of behavior that may contribute to the symptoms you experience. Many people experience significant relief from chronic emotional issues by working with a therapist.  


At HealthOne, we want our clients to understand that the benefits of therapy develop over timeIt’s important to understand that while they are not immediate, the positive and beneficial results of going to therapy can significantly improve your life. Many individuals leave therapy with a greater sense of clarity and stronger feeling of empowerment. 


You can always be completely honest with your therapist. If you feel like the approach they are using is not helping you or your problems, you can share that information with them and discuss your expectations together.

Why go to therapy?

Therapy is an effective way to receive support and guidance when you are struggling with emotions, life challenges, or your mental health. The primary goal of mental health counselling is to improve your quality of life and well-being. 


Many people incorrectly assume that your mental health must be seriously ‘wrong’ in order to go to therapy. In reality, people in all circumstances can benefit from it and all people can feel a greater sense of ease in navigating life’s challenges after they go to therapy. 


Although mental health challenges are extremely common, a lot of people try to deal with them on their own. It can be difficult to overcome these challenges by yourself. Speaking with a therapist gives you a safe space to discuss your experience, receive professional support, learn evidence-based techniques to improve your quality of life, and feel a deeper connection to your sense of self. 


Our experienced team of professionals are passionate about supporting you through all of life’s stages and the challenges that come with them so you can live an inspired life. They can support you in dealing with temporary responses to circumstances (I.e., burnout, transitions, break-ups, grief, work-related problems, immigration), mood conditions (depression), and anxiety-related issues (anxiety, panic, phobias, ADHD). 

What is online therapy?

Online therapy is a type of mental health therapy that takes place via video-chat or telephone. It is an easy and accessible way to speak with our registered mental health professionals from the comfort of home. People may choose to book online therapy sessions as an alternative to in-office therapy sessions. 


At HealthOne, all of our online therapy sessions are done on a HIPPA-compliant privacy-secured platform. We encourage you to book a virtual appointment to determine if online therapy is right for you. 

Is my therapy session confidential?

At HealthOne, we believe that confidentiality is a fundamental component of all forms of talk-therapy. Knowing that you can speak openly and honestly with your therapist helps build trust, create a stronger relationship, and allows you to feel more secure about your experience with therapy. 


All of our therapists at HealthOne are legally and ethically bound to keep their sessions confidential. Your therapist must get your written consent to release personal health information about you to any other member of your health care team, including a consultation about your treatment with your family doctor or psychiatrist. 


The only exception to this rule is if your therapist has a reason to believe you may harm yourself or others. This exception exists for the sole reason of protecting your safety. In this case, they must turn to the appropriate resources to make sure that you (or others) are safe from harm.  

How many sessions do I need?


Some therapies are short in length. You can work with one of our therapists to manage stress or find a solution to a unique situation you’re experiencing using short-termfocused approaches.  



Some therapies need a medium length approach. You can work with one of our therapists for mood problems such as depression, relationship issues, or concerns surrounding anxiety. 



For more stressful concerns, you may benefit from lengthier treatments depending on your symptoms. One of our therapists can help you with recurring problems which may include relationship patterns, mental illness, health conditions, impulse control issues such as disordered eating, online addictions, problematic substance use, and trauma.
