We began our research with a direct search into the total number of gastric sleeve surgeries performed in Ontario, Canada, on government websites. We were able to locate exact numbers on bariatric surgeries by type of procedure done at Canadian public hospitals through 2013/2014 within a report issued by the Canadian Institute for Health Information. This report allowed us to note that, while Ontario got off to a relatively slow start in the share of gastric sleeve surgeries performed, the province appeared to have mainly caught up in this type of procedure by the end of 2014.
We attempted to access data on more recent years from the Canadian Institute for Health Information but were unable to do so, either because it is not available or because the more recent data is in reports that must be paid for. However, we were able to locate a portion of this information through the year 2017/2018 from a 2019 report issued by an obesity-related charity organization. Unfortunately, this report did not break down the Ontario numbers by type of procedure, so we were unable to get a hard number and percentage for gastric sleeve surgeries performed for the more recent years.
Next, we attempted to find the missing information from the Ontario Ministry of Health and Long-term care, as well as an established professional network for bariatric services, but we were unable to do so. When that strategy failed, we sought relevant information from sources covering global trends in gastric sleeve surgery but were unable to uncover any new information on Ontario, or even Canada, through this method. We also searched for information on the public/private breakdown of these procedures. We were able to locate one estimate for Canada as a whole that appears to be reliable. While we were unable to uncover more precise numbers on private procedures, this line of research did indicate that waiting times within the public healthcare system may be considered a problem.
Given the limits of the available data, we used the most recent percentage of bariatric surgeries that are a gastric sleeve for Canada, as a whole, to estimate the number of these procedures that occurred in Ontario in the most recent year. Also, to calculate CAGR, we used an online calculator.
