 The table above presents key information about the seven modular reactors that appear to have achieved the most support from the nuclear sector in Canada. For seven, proponents or backers have associated the reactor design with a potential  site. The eighth, NuScale, has the support of major nuclear power companies (OPG and Bruce Power) in Ontario.  Most of this information was found through the CNSC SMR page  ​HERE or the IAEA's 2020 report HERE
Click on the links (underlined words) in the table to learn more about the vendor, the backer, or the CNSC review report.​

Info about the Canadian Nuclear Safety Commission's "Pre-licensing Vendor Review" is HERE
View Stop SMRs tracking table as a google sheet HERE
In March 2023 the OECD's Nuclear Energy Agency published a report summarizing 21 reactor designs 'moving forward', including the ARC100, BWRX-300, MMR, Moltex (under the name 'Stable Salt Reactor - Wasteburner'), NuScale (in the T of C as VOYGR), U-Battery, eVinci, and Xe-100, all identified as having activity in Canada. The "analysis" in the report is two pagers per reactor design, the first fully occupied by graphics indicating the report authors' assessment of project status, and the second being a brief summary consisting of one paragraph each on licening, siting, financing, supply chain, engagement and fuel. The report is HERE. The launch webinar HERE.
In September 2020, the International Atomic Energy Agency produced the report ADVANCES IN SMALL MODULAR REACTOR TECHNOLOGY DEVELOPMENTS 2020 Edition. This 354 page report provides 3-4 page summaries of over 70 designs, including all those listed in the two tables on this page. The fuel and waste summaries in the above table are from this source.
The table below presents key information about there small modular reactors which also remain in the CNSC Vendor Design Review process but have not been the subject of any announcements of Canadian ​government funding or utility backing, and have not been associated with a particular site in Canada.
