About Dimensions

Combining neuroscientific research with Plant Ceremony and luxurious hospitality, Dimensions focuses on restorative well-being and transformational growth. Dimensions Retreats help improve and transform lives by drawing on the restorative power of nature, spa rituals, remarkable cuisine and psychedelic Plant Ceremony in a growing collection of safe, legal and luxurious accommodations in natural settings. 


Algonquin Highlands



Dimensions Retreats combine ancient practices with modern neuroscience, braiding the practices of poly-vagal theory (calming the nervous system, pendulation of emotional states, self-regulation, titrating approaches to challenging material and stored trauma) with psychedelic medicine, all within the context of nature-oriented retreats. In this way, Dimensions leverages the healing power of nature with the transformational possibilities of psychedelics, couched within a supportive, guided, safe and informed therapeutic environment oriented towards calming and restoring self-regulation to the nervous system.



Make time for a Reset. Increased urbanization, decreases in horticulture, deforestation, loss of bio-diversity and human dependence on information technologies, electronic devices and the looming meta-verse have increasingly created a widespread nature-deficit disorder.



Dimensions retreat participants return home not simply with transformational experiences, but with a clear plan to sustain life improvements. Integration at Dimensions includes an after-care plan with specific attention directed at the following areas: diet and nutrition, movement and exercise, personalized meditation, visualization and movement practices, access to curated Dimensions playlists, mudras and chants to practice, plans for integration therapy, herbal and supplement planning, virtual group sessions and plans for follow-up and check-ins with Dimension’s therapists.

The Ascend Four Week program

Your introductory ASCEND Retreat includes one week of preparation and features:

  • One virtual group meeting – A virtual group meeting establishes a connection between facilitators and guests. The meeting is designed to prepare our guests for their three night ASCEND Retreat experience at Dimensions Algonquin Highlands. Our guests will begin connecting with their intentions, receive psychoeducation on cannabis as a psychedelic, Plant Medicine and ceremonial experiences, window of tolerance and emotional regulation, trauma, and how to create the appropriate mindset for plant medicine ceremonies.
  • Dietary advice – Dietary guidelines and plant medicine will be provided in preparation for the Retreat. This helps to prepare the body by purification. As a result of these dietary recommendations, the physical body is prepared to receive plant medicine while improving brain and brain-gut health.
  • Videos – Dimensions offers psychoeducation to provide information on trauma, dissociation, window of tolerance, emotional regulation, clinical issues (Anxiety, Depression, PTSD), Polyvagal theory, Psychedelic Assisted Psychotherapy, and Plant Medicines (Cannabis, Psilocybin, Ayahuasca, etc.)
  • Worksheets – Through our worksheets, we help guests develop a deeper understanding of themselves, their current issues, and their intentions for healing.
  • Audio Meditations – These audio meditations teach our guests self-regulation skills, mindfulness-based practices, self-reflection, and self-exploration practices to prepare for their Retreat experience.
  • Packing Lists – Guests are encouraged to bring small, cherished items for use in ceremony (sacred objects, photos of loved ones, or personal belongings that make one feel secure and connected)

  • Videos – Psychoeducation on the different stages of integration, including remembering, reprocessing, reorienting, re-consolidating memories, and taking new actions.

Getting there

Map + Location

45° 06′ 22.48″ N, 78° 39′ 29.55″ W

Dimensions Algonquin Highlands can be reached from Toronto by car, helicopter or private air. Driving from Toronto via Highway 400 North with a connection to Highway 11N and then a right turn to 118 West brings guests to our door in approximately three hours. From Billy Bishop Toronto City Airport or Toronto Pearson International Airport, flight time to the nearby Stanhope Municipal Airport (CND4) is one hour. The Retreat spans nearly 16 hectares of woodlands, and is located in Stanhope Township along the shores of Maple Lake, at 1218 Canopy Lane. This forest access road leads south from the Township’s Airport Road, just 6 kilometres from the nearest community of Carnarvon and 20 kilometres from the larger town of Minden, Ontario.

Our lakeside Northern Ontario setting featuring rugged hills and an extensive network of forest trails is the optimal setting to enjoy a Canadian winter or observe the first signs of a changing season. Time spent with us off the beaten path will serve as an exclusive prelude to Dimensions Retreat’s growing curriculum and the opening of a global collection of several permanent Retreat destinations for deep healing and well-being. You will learn why the combination of natural plant medicines and psychotherapeutic technique is a powerful strategy to address issues and reduce the impact of trauma – especially when healing is set in natural surroundings.

Q + A

Published trials and recent research show that psychedelics are useful in treating depression, anxiety, stress, trauma, addictions, migraines, post-traumatic stress, obsessive–compulsive disorder, eating disorders and end-of-life distress, as well as in improving general well-being. Importantly, psychedelics also show promise in safely and efficiently treating many of these conditions where other approaches have failed.

In conjunction with Queen’s University and Health Canada, Dimensions is developing a robust research agenda to continue exploring the benefits and limits of psychedelics. Read our blog for more information about current research trials and findings.

Participation in our programs is not dependent on a physician’s referral, but all guests must participate in our intake and assessment process prior to Retreat, including a medical and psychological assessment to determine your physical and mental readiness for our programs.

Dimensions believes in whole plant medicine. The type of plant-based psychedelics offered at our safe, legal and luxurious Retreats differs depending on local laws in the regions where our locations operate.

Yes, we do have two-night retreat options at our Dimensions Algonquin Highlands property and upon request we do conduct ceremonies with guests who wish to abstain from plant medicines.

Without exception, Dimensions complies with local laws and only provides plant-based medicines that are legal in a Retreat’s location.

When used therapeutically in professionally supervised treatments, psychedelics can help you safely explore past experiences and memories that are normally difficult to tolerate or access. By quieting the part of the brain associated with ego, psychedelics disrupt patterns of negative thinking and allow for the creation of new perceptions. In these expanded states of consciousness, you’re better able to develop – and maintain – a deeper, more compassionate sense of yourself and your place in the world, leading to better mental health and improved well-being.

Used therapeutically, psychedelics are low-risk. At Dimensions, safety is our priority. We incorporate multiple measures to optimize your wellness journey and ensure your stay with us is safe and effective from beginning to end.

Psychedelic-assisted therapy combines psychedelic experiences with complementary therapeutic processes to help you reflect, reset and reconnect. 

The therapeutic effects of psychedelics are not due simply to their physiological effects. Rather, they are the result of interactions between these physiological effects, the therapeutic setting and your mindset. Dimensions wellness programs offer a diverse array of therapeutic somatic modalities such as massage, float tanks and acupuncture to help you reconnect to your body. Instruction in breathing, meditation, mindfulness and similar practices deepens your experience. Activities in nature, exceptional culinary selections and the serene design at our luxurious Retreats are essential supports on your journey to well-being. Through all of these elements, our expert team pays careful attention to your emotional, physical, mental and spiritual development.

When specific strains of cannabis sativa are blended together in a particular way, their psychoactive components – notably, THC, CBD, CBN, CBG and CBC, as well as the terpene profile – can elicit deep psychedelic states similar to other classic psychedelics such as ayahuasca and psilocybin. When used in a therapeutic or ceremonial setting, cannabis addresses physical traumas in the fascia, tendons, muscles and bones – not just the trauma held in nervous system memories, emotions and personality structures.  


However, cannabis differs from other psychedelics because you can retain your agency or sense of control. This often means you can navigate the experience more skilfully and with greater ease, and you can pause the experience.

Our guests’ privacy is paramount. Any information shared during the Retreat is confidential. Dimensions’ therapeutic staff comprises professionals who hold designations from recognized licensing bodies, and the entire staff have received extensive training on privacy protocols. Our digital platforms and guest services systems comply fully with HIPAA and PHIPA privacy regulations. Your fellow guests must also agree to maintain the confidentiality of other participants’ experiences and identities.
