First, let's go through the direct effects of the Meech Lake Accord itself entering the Constitution. (
Here's a copy of the original communiqué)
-The flashiest part of the Accord was the plainly obvious admission that Quebec constituted a
'distinct society' within Canada. The problem is that this 'distinct society' clause would be considered an interpretive clause in the country's constitution. Effectively, Mulroney had given Quebec another Notwithstanding Clause, a piece of constitutional cover against the Charter of Rights that only they could use. If it's used only as a last resort under extreme circumstnaces, like the Notwithstanding Clause is presently, it could be a useful tool for Quebec to shed light on what it sees as dangers to its identity. If overused to the point where it becomes the norm, the federal government might as well have handed them sovereignty.
-The Accord also ensured that the federal government would need to make agreements with the provinces when setting
immigration policy. This probably wouldn't be much of an issue, at least until the mid-tens when a refugee crisis turned immigration into a major political inflection point.
-Under Meech,
Senators and
Supreme Court justices were to be selected out of lists from each province. Since nowadays both institutions spend their time keeping away from the public eye, the Prime Minister would likely have picked the least controversial of all the choices. Unless the governing party finds itself without any provincial allies, this is unlikely to cause tension.
-The right to
opt out of national programs with compensation would be constitutionally enshrined by the Meech Lake Accord, provided the province opting out enacts its own program that meets federal standards. Nowadays this is usually how a federal government puts through a thorny national policy already (see Pricing, Carbon), so little change there.
-Future constitutional amendments would be made harder, but regular
First Ministers' Conferences would become mandated. There's no guarantee these meetings will result in anything happening, of course. I predict, rather cynically, that the average Conference will turn into a prolonged press conference, where Premiers and Prime Ministers lay out their positions and engage in 'dialogues' where they trade notes written well in advance. Activists will converge on the meeting site to demand change. ("What do we want? A climate change agreement/Senate reform/reconciliation/childcare! When do we want it? Now!") One big photo-op for all involved.

Now, don't worry; Brian Mulroney's still screwed six different ways. He's still in power thanks to an unweldy coalition of francophones and francophobes, he's still only able to mend that rift through egregious amounts of patronage, he's still willing to try for a grand bargain on abortion law, he's still about to step right into a recession and introduce a sales tax. It's possible that Mulroney can't find eight senators from the provinces who are willing to pass the GST, but hardly likely.
And now for the sixty-four-thousand-dollar question:
How does this effect the Election of 1993? Well, the Tories are obviously going to hold onto the Quebec nationalists' support. If the party thinks they've got 'em in the bag, they could be willing to trade in the old horse for Campbell or some other new face. If they're worried about holding down Laval, they'll stick with Brian.
The Liberal leadership is David Peterson's for the taking. Chrétien was already having trouble attacking Meech when it wasn't settled law, and the Accord passing would probably mean curtains for his Prime Ministerial prospects. By contrast, Peterson was still on top of the world in Ontario, still a prominent backer of the new constitutional paradigm, and still credible on pocketbook issues like free trade and taxes.
With the Tories having a tighter hold over Quebec, things look a lot better for Dave Barrett's pitch to the NDP. He might win the leadership over Audrey McLaghlin, or even some other former western premier. Bob Rae watches hungrily from the sidelines, waiting for the next election's bloodbath to make his move.
Even without regional parties like the Bloc Quebecois and the Reform party, the election will likely match the contours of the country. The Liberals will take advantage of unemployment and the deficit to dominate in Ontario and the Maritimes. The Tories will sweep outer Quebec, while the New Democrats will nip at their heels in the West. The final results, based on my back-of-a-napkin math:
Liberal Party - 140
Progressive Conservative Party - 110
New Democratic Party - 45
(Reform might win a few seats too, I dunno)
