Quebec once had a small village called Dixie.
Where is it now?
UPDATE: Enough of you were close that I'll give it to you. Dixie was a small village (hamlet?) in the 19th century in what is now the lakeshore in western Lachine and eastern Dorval. It had a population of about 300 when it was made part of Lachine. You can see a map of it here from 1894, and another here from 1913 after it became part of Lachine. It only had two roads, Lakeshore Road (now St. Joseph Blvd.) and a "road to station", which is now 55th Ave.
As Zeke points out below, the name remains in use as that of a small uninhabited island just offshore near where the old town was. And as Jean Naimard points out, there's also a street in Lachine called Rue Dixie.

Where is this?
UPDATE (Sept. 30): It took a while, but Pelle Moulante got the right answer below. This photo was taken from the tip of the Parc du Bout-de-l'Île, both the northernmost and easternmost point on the island of Montreal.
The waves are the result of pleasure boaters whizzing back and forth along the St. Lawrence, and the island in the distance is Île à l'Aigle.

Where is this guy on his high horse?
UPDATE: Can't fool you folks. It's the Boer War Memorial (you do remember the Boer Wars, right?) in the newly renovated Dorchester Square. This is (according to Wikipedia, and we gotta trust that) the only equestrian statue in Montreal.
The line formed by 55th Ave., Côte de Liesse (Highway 520), Highway 13, Côte Vertu Blvd., Sauvé St., and Pie-IX Blvd. represents what?
UPDATE: A bunch of you got this right, though NDGer was the first. It's the border between the AMT's Zones 1 and 2 (grey and pink on this map).
The AMT's zoning system (where higher-numbered zones pay more to use commuter trains and multiple-network bus trips) is roughly based on the distance to downtown Montreal (assuming that everyone is travelling downtown to work, which of course isn't always the case).
There are some quirks though, for example Lachine is considered Zone 1 while Longueuil, which is much closer to downtown, is Zone 3. Similarly, Kahnawake (Zone 5) is closer than Pointe-Claire (Zone 2), and most of the Zone 8 territories are closer than Rigaud (Zone 6), though that won't matter once Rigaud loses its train service on July 1.
Thanks to SMS for this week's question.

What bridge is this?
UPDATE: Yeah, I didn't think this would take too long. SMS is the first with the right answer: It's the bridge part of the Louis-Hippolyte Lafontaine Bridge-Tunnel, connecting the Boucherville islands with the south shore.

Where is this?
UPDATE: Chris gets this right: It's Papineau Ave., looking north at the Des Carrières overpass. A (really smelly) staircase connects the two streets for pedestrians who don't want to walk all the way to Rosemont and back. But only for one side of Papineau. The other side is boarded off because the stairs are in an advanced state of decay.

Where is this?
UPDATE: This one didn't take you long. It is, indeed, École Irénée-Lussier on Hochelaga at the corner of Pie-IX.

What does this childish scribble of a drawing represent?
UPDATE: Steve Hatton needed only seven minutes to get this one. These lines represent the redesign of de Maisonneuve Blvd. between St. Laurent and St. Urbain.

De Maisonneuve Blvd., looking west toward Clark St.
As of a few months ago, drivers (and cyclists) heading west no longer have a gradual curve that takes them around Place des Arts, but rather a stop sign and hard right onto Clark before they turn left back onto de Maisonneuve. This new layout gives more space for building construction nearby, but also reduces the speed of traffic.
In order to accommodate all the cars, the direction of Clark (a one-way street) is reversed between de Maisonneuve and ... uhh ... de Maisonneuve. This effectively reserves that stretch of road for drivers heading west on de Maisonneuve.
A little history
The path of de Maisonneuve Blvd. in this area is a bit strange, particularly because it curves upward to run right next to Ontario St. The path is entirely a result of the path of the green line of the metro between St. Laurent and Place des Arts stations. Before the metro's construction, de Maisonneuve Blvd. didn't exist. What we now know as that boulevard was a handful of unconnected roads, including de Montigny St. (everything east of St. Laurent), the last bit of which (the lower red portion in the image at top) has been removed with this redesign.
UPDATE (June 9): It's been pointed out below that a tiny stretch of de Montigny still exists, between Clark and St. Urbain, under this new design.

What - and where - is this?
UPDATE (April 27): John is the first to get this right below: This is the inside of what used to be a bus shelter on Pie-IX Blvd., specifically the one at Jarry St.
I didn't know it when I posted this question, but it's actually somewhat of a trick one. You see, the objects in this photograph aren't there anymore.

Where is this?
UPDATE (April 26): One comment was on the right trail, but nobody posted a correct answer a week later, so here it is: It's the end of Legendre St. in St. Michel, looking toward the old quarry. That tower at the centre - your guess is as good as mine.
