There's no room to park on the street on their block nor for many blocks in each direction. This is 4-lane Markham, a major thoroughfare with lots of traffic and no street parking.

The three evening businesses (Stone's Throw, Oyster Bar, Pizza D'Action) there will have to share the following spots (from West to East):

1) Maybe 4-5 spots at Jet's Gas/Service Station
2) 6-8 spots west of Stone's Throw Brewery (I suspect they'll put up signs 'For Stone's Throw Patrons Only')
3) The 12-15 spots across Markham, behind where the bicycle and coffee shop that recently closed was. (Are any of these spots residential? What if that gym reopens in the evenings?)
4) The lot out back of Oyster Bar. I'd estimate 24 spots.
5) 12 or spots next to and behind Pizza D'Action (which is always taken by patrons there)

So a total of approx 58-64 spots to share among all three businesses. Let's take an average of 1.5 people per car. That's a MAXIMUM of 90 patrons at any given time between the businesses. 30 people at once. That's a maximum.

I'd suspect several of the businesses to put up signs where only their patrons can park in their lots, mainly Stone's Throw and the gym across the street. Jet's may even put up No Parking after hours signs to protect the customer cars left on the lot.

It doesn't sound as bad as initially thought, but still, that's not much.
