I ride 46-16 in montreal and I dont have any problem, ok i maybe wont go up the mont royal every day but .... all the other "hills" like sherbrooke and streets like these can be done .... if you don't stop right at the bottom ....
Like on st-hubert or papineau when you go under the "bridge" and you have to go through the "hill" on the other side you will notice all the bike are going SUPER SLOW when going up, but since you have one speed you actually speed up on you way down and rush to make it on the top and actually pass by all the people going 2mhp on their geared bike.
Montreal is pretty flat, even when you face up hills like ontario-sherbrooke you can always find a street that is easier to climb ...
If you old or kinda noticeably out of shape your maybe better with a geared bike. Dont know what you ride now but a 46-16 ( stock purefix ratio ) is kinda like between the speed no.2 and no.3 on a bixi, I never faced a hill I could not climb in montreal ( exept mont royal never even wanted to try it since its already a pain with a geared bike on the biggest gears ).
