SMS Terms: Sigma Surveillance Text Support

Last updated: September 23, 2026

1. About the program

"Sigma Surveillance Text Support" is the text-message (SMS) program of Sigma Surveillance Inc. ("Sigma", "we", "us"), 285 Main St. N, Acton, Ontario L7J 1W7, Canada. Through it we:

  • reply to people who text us, or who ask us on sigmasurveillance.ca to text them, about an inquiry;
  • send quote follow-ups, site-assessment scheduling and reminders, and customer-support messages.

We do not send marketing or promotional text messages through this program.

2. How you join

You join by (a) texting us at (416) 477-5589 (Canada) or (209) 900-5884 (USA), or (b) ticking the optional text-message box on a form on sigmasurveillance.ca. Consent to receive text messages is not a condition of any purchase.

3. Message frequency

Message frequency varies. Inquiry and support conversations usually involve a few messages per request.

4. Costs

Message and data rates may apply. Sigma does not charge for text messages. Ask your mobile carrier about your plan.

5. How to stop

Reply STOP (or UNSUBSCRIBE, CANCEL, END, QUIT, REVOKE, OPT OUT or ARRET) to the number that texted you. You will receive one confirmation message and no further texts from that number.
