Hey folks got the same thing on Oct 5 ... If I ever see the person affixing this type of tag I will take matters into my own hands!  Thx for all the posts.

Got this same notice at my door this morning as well, with the exact phone number.  I'm in the Mississauga area.

Reported to the Canadian Anti Fraud Centre, please be cautious and do not call the number listed on the slip.

They have not stopped it. Just got the door tag today

I've got a door tag for a delivery today.  The company name was "MCS", but I never heard of.
After the Google search, I found this website and these...
http://whocallsme.com/Phone-Number.aspx/(289) 232-3031/
http://whocallsme.com/Phone-Number.aspx/(905) 232-5326/
Different number, different company name,... Anyway, it's a scam or at least it is not a delivery notice.
Don't even try to call the number.

Hey guys, dont call the police just toss the notice in your garbage, i spoke to the fraud bureau and they told me they have spoken to the company responsible for it and no one should contact them, its just their marketing way which is unacceptable and police have told them to stop it immediately.

I hope it resolves the matter. Thank you all.. i received this notice as well today

got this crap on my door. wish i caught the f****r taping it.
