This is probably a massive nothingburger, but Gurratan Singh is a lobbyist for Metro?
For those uninitiated, Metro is a grocery store chain, and the main competitor to Loblaw, a company that has been a huge target of the NDP's attacks. Gurratan Singh is a former Ontario NDP MPP and the brother of Jagmeet Singh. The two of them are known to be very close, including in a political capacity.
Guys, I'm not alleging that Jagmeet is a Metro plant lmao. Gurratan is a defeated politician, and defeated politicians turn into lobbyists. It's more the fact that NDP's line is always some sanctimonious rendition of "we're not like those other politicians, we care about people, not profit. Between this and NDP supporters acting like landlords are earthly manifestations of the devil (while Jagmeet's wife is gasp a landlord), come on guys. Let's stop pretending that you're above wanting to make money like the rest of us.
A politician's brother being a lobbyist could cause a conflict of interest if, somehow, Singh became PM or a Minister regulating supermarkets like Metro, but otherwise I don't see this as a particular issue.
And the piece about landlords reminds me of NOVA politics (in fact the housing-centric nature of urban Canadian politics reminds me quite a lot of DC and NOVA politics). A lot of talk about how landlords and developers are evil, terrible etc - but many people around here are involved in that line of work. They can't all be bad!
