There's plenty to be made - it's just very under the radar.
Anecdotally, extended family of mine run a fairly decent sized construction contracting company out in BC (Vancouver Island and Lower Mainland), and have been having family members and family friends donate as a group for both Conservative and NDP MLAs for over a decade now, as well as helping organize voter drives and non-partisan activities at Gurdwaras (if partisan activities came up, they tended to be in Punjabi and thus not reported on - but tbf, in depth local news is dead in much of Canada as well outside of metros).
Lobbying is common across democracies, but how it manifests is different. I feel that there is also a level of visibility into the American system that really highlights bad actors, but similar scrutiny isn't as common in other countries other than maybe the UK.
