Eleven of these are located in the Canadian Shield of Quebec, and five are located in the Cordillera of British Columbia and Alberta. Six of these large reservoirs, along with two other smaller reservoirs, have been associated with reservoir‐triggered seismicity (RTS). The proportion of reservoirs with an RTS that is larger than Nuttli magnitude MN 3.0 (25%; i.e., four cases) is similar to the one for worldwide counterparts (22%). All RTS cases are located in the Canadian Shield of Quebec, which is an area that is weakly seismically active. RTS is of a small magnitude (the largest event was magnitude MN 4.1). Based on the known cases of RTS and those that had no associated seismicity, there are a few conclusions that can be drawn. Before the mid 1970s, many potential triggered earthquakes could have been below the detection threshold that was offered by the Canadian National Seismograph Network (CNSN) at the time (generally magnitude 3.5). The weight of the reservoirs does not appear to be the main factor that triggers RTS; two of the reservoirs with the largest volumes do not have any associated activity. In all RTS cases, it is almost impossible to relate the activity to specific fault characteristics. In some RTS cases, filling was not completed when the RTS started. For these cases, it is not easy to distinguish between a rapid response (such as the weight of the reservoir increasing the pore‐fluid pressures at depth) and the delayed type of response, in which the pore‐fluid pressure diffusion leads to reactivation of the fault. For the majority of RTS cases, however, a delayed‐response type appears more likely; that is, it is more likely that activity that is started shortly after the initial impoundment will continue for many months, sometimes in swarms, and finally stop after a few years.
