Toronto police had an important message Saturday for anyone who spotted military activity down by the city’s waterfront: “We are not being invaded.”

Canadian soldiers and army combat engineers conducted assault boat landing exercises on Toronto’s western beaches, including Sunnyside Park, Sir Casimir Gzowski Park and Hanlan’s Point Beach on the Toronto Islands.

In alerting the public that there was no cause for alarm and the exercises were indeed only a simulation, Toronto police tweeted:

The advisory was retweeted hundreds of times and drew humorous commentary from Canadians as well as our neighbours to the south:

The soldiers who conducted the training are members of the 32 Combat Engineer Regiment. They say the skills and techniques they are practising will help them in overseas operations and in response to domestic emergencies.
