Ottawa and the provinces and territories could have another $1 billion a year in tax revenues to split after pot becomes legal next year, but Windsor's mayor is hoping municipalities will get a cut of the revenue as well.

"They will have to flow some funds to municipalities to deal with issues that arise and for policing," Mayor Drew Dilkens says, noting the city doesn't get any tax revenue for alcohol sales either. "But as this rolls out, we will see issues as a border city."

This is in reaction to the federal tax proposal outlined by Liberal MP Bill Blair, the former Toronto police chief and the government's point man on legalizing marijuana. It kicks off a period of public consultations that ends Dec. 7.

That, Blair said, gives the government just enough time to solicit comments on the proposal so that federal, provincial and territorial finance ministers can discuss it when they meet in Ottawa Dec. 10-11.

Blair notes municipalities have indicated they deserve a share of the revenues.

"We have recognized right from the outset that municipalities are an important stakeholder, and that they have a significant role to play in ensuring that the regulatory regime that is put in place is effective in achieving our public purpose aims, of protecting kids and keeping communities safe," Blair said.

"As I've travelled across the country, I've always made a point in virtually every town I've gone into to go and meet with the mayor and the local chief of police to hear that perspective, and we've carried their concerns back, and we've responded to that already in a quite significant way."

Mayor Dilkens tells CTV Windsor he would like to see that reflected in what the city receives.

"Cities need some guaranteed revenue streams from this program to deal with issues," Dilkens says.

The government has already committed resources to municipalities, including $81 million for municipal and Indigenous police services to help offset the cost of additional training and resources, he added.

The federal plan would add an excise tax of $1 per gram of marijuana or 10 per cent of the final retail price, whichever is higher, with the revenues to be divided equally between Ottawa and the provinces and territories.

The final price, including provincial and federal sales taxes, would vary by jurisdiction, since the combined total is in some provinces is higher than in others. On an $8 gram of pot sold in Ontario, for instance, the final purchase price would be $10.17, with a $1 excise tax and $1.17 HST. In New Brunswick, it would be $10.35.

Alberta, which has no provincial sales taxes, could see the cheapest pot in the country at just $9.45 total for an $8 gram of weed.

"I'm very comfortable that the level of taxation that has been determined as appropriate in this case achieves our goals of keeping the price sufficiently low to be competitive with an illicit market, while at the same time not creating an incentive for the consumption and purchase of this drug," said Blair.

"It's a matter of finding the right level of taxation and price in order to achieve both of those very important public purpose aims. I believe that the work that we have done sets a very appropriate level."

Blair gave $1 billion a year as a very rough estimate of how much Canada and provinces stand to raise from the plan, although that number is at the high end of the scale, he warned, since so much depends on just how many people will end up buying marijuana once it becomes legal.

"We're working very closely right now to determine what the size of that market will be," he said.

He said determining the market is very difficult, but the tax will end up being between one-fifth and one-quarter of the final price, with tax revenues to be split 50-50 with the provinces and territories.

"The market is currently controlled almost 100 per cent by criminals," Blair said. "It's an illicit market. Quite frankly, they don't share a lot of data on the size of their market, so right now we're operating on estimates."

The taxes would be levied on both on fresh and dried marijuana, pot-infused oils and seeds and seedlings used for home cultivation. Revenues would be used for public education, research, enforcement and other activities around the regulation and administration of legal pot.

The 50-50 tax revenue split idea has already rankled at least one premier -- B.C.'s John Horgan -- who complained that the provinces won't be getting a fair share, considering they will be doing the bulk of the heavy lifting on legalization, including policing, distributing and regulating the sale of marijuana.

"It is part of an ongoing discussion that our finance minister is having with his counterparts, provincially and territorially," Blair said. "It would be inappropriate of me to presume the results of the discussions that are currently taking place ... there is still work to be done in the consultations."
