The provinces are set to get a better share of an excise tax on marijuana sales, but Manitoba hasn't signed on to the agreement yet.

At a federal-territorial-provincial meeting of finance ministers yesterday, a proposed 50/50 split (on an excise tax of either 10 per cent of the retail price of marijuana or $1 per gram, whichever is higher) became 75/25 in favour of the provinces.

But Manitoba finance minister Cameron Friesen says Manitoba still hasn't decided if it will opt in or out.

"There wasn't a kind of a drop-dead date today," Friesen told reporters yesterday over the phone from Ottawa. "There were issues that were not fully discussed today that led Manitoba to the decision to not sign on to this agreement."

Friesen says Manitoba needs more information, and says it appears the federal government's commitment to awareness and advertising is inadequate. He also listed border security and what the impact on cross-border trade will be as issues still needing to be addressed.

Friesen says the province has an oglibation to keep citizens safe, and the province is looking at cannabis through the lens of safety, both for people who decide to use marijuana and those who don't.

Manitoba is the lone holdout; all other provinces and territories, and the federal government, signed the agreement. Friesen says in the coming days, Manitoba senior officials will be in discussion with federal officials.
