Reporting Algae Blooms

What should I do if I think I am in the presence of a bloom of blue-green algae?

Anyone who suspects the presence of a bloom is invited to report this immediately to the concerned regional office of one of the following ways:

  • At all times: by using the visual statement form and sending it by fax or email to the regional office of the Ministry
  • During office hours: by calling the regional office (e.g. Outaouais – Gatineau 819 772-3434) and asking for the manager of cyanobacteria file;
  • Outside office hours: by contacting Environmental-Emergency at 1 866 694-5454.

How does the Ministry respond?

The MDDELCC conducts a field visit to make observations and take samples. The Ministry will then communicate the information to the municipalities concerned and the person(s) who made the report.

REMEMBER – not all blue green algae is Cyanobacteria or necessarily toxic. However, when in doubt stay out!
