The Canadian Press Green Party Leader Elizabeth May congratulated Jagmeet Singh on winning the NDP leadership race. She also gave him a quick reminder on Canada's electoral system.

Shortly after he was declared the federal NDP's new leader Sunday, Jagmeet Singh announced to his party's supporters that he was officially kicking off his "campaign" to be the next prime minister of Canada. On Twitter, Singh's team sent out snippets of his speech from his account, including this line:

That's why today, I'm officially launching my campaign to be the next Prime Minister of Canada. #LoveAndCourage — Jagmeet Singh (@theJagmeetSingh) October 1, 2017

That apparently didn't sit well with Green Party Leader Elizabeth May, who hours later tweeted at the Ontario MPP to remind him the government's top job is not an elected one. "I welcome you to federal politics and hope 4 friendship," May wrote, "but Canada does not elect Prime Ministers." I welcome you to federal politics and hope 4 friendship, but Canada does not elect Prime Ministers. #notUSA@theJagmeetSingh@acoyne@NDP — Elizabeth May (@ElizabethMay) October 2, 2017 May's clarification is not inaccurate, of course, but some users on Twitter thought her tweet was a bit unnecessary — especially since it was coupled with a congratulatory message. One user called it "incredibly petty," while another said the remark was a bit heavy on the snark.

Wow. That was about as condescending a "welcome" as they get. You're putting words into his mouth to make him appear incompetent/uneducated. — M (@MFIoFV) October 2, 2017

Wow. Snark doesn't become you, @ElizabethMay. A simple "congratulations" would have done nicely. — cal marcoux (@cmarcoux) October 2, 2017

May replied to one of the users criticizing her comment and expanded on the "notUSA" hashtag she used in her comment to Singh. "Language matters. We do not elect a PM. We elect 338 MPs — presidentializing our system is a worrying trend," she wrote. Singh never said he would be elected prime minister. He did, however, say shortly after he was chosen as NDP leader that his "run" for the top job has begun.

Thank you, New Democrats. The run for Prime Minister begins now 🇨🇦#LoveAndCouragepic.twitter.com/FDUem3pfGT — Jagmeet Singh (@theJagmeetSingh) October 1, 2017

What Singh will definitely need to be elected to, however, is a federal seat. His lack of a spot in the House of Commons was seen as a worrying sign to some members of his party, including outgoing leader Tom Mulcair. "I think it's important to have a seat in the House of Commons if we're leading a political party," Mulcair said last month. "I think that ideally, you know, you should be there."

Later in the leadership race, as his campaign gained momentum, he appeared to be more open to the idea of running before the next election. Also On HuffPost:
