The worker, posting on Twitter with the username Sunith Baheerathan, indicated he was at work at the Mr. Lube location in Concord when he put out the request for marijuana Tuesday, the Canadian Broadcasting Corp. reported Thursday.
"Any dealers in Vaughan wanna make a 20sac chop? Come to Keele/Langstaff Mr. Lube, need a spliff or two to help me last this open to close," he tweeted.
However, instead of getting a response from a dealer, the tweet received a reply from the York Regional Police.
"Awesome! Can we come too?" the reply tweet read.
Police brought the tweet to the attention of Mr. Lube bosses, who addressed the controversy Tuesday night on the store's Twitter page.
"Thank you to the York Regional Police for your help and great work. The matter has now been handled," the company said.
Sunith Baheerathan confirmed on his Twitter account that he was fired.
"Just got the call of termination," he tweeted.
