Good for you JDL!
I hope you have fun at the Tour de l'Īle. Be aware that it's nowhere near a century: it's really an occasion for cyclists to "take back the road" at the speed of about 10 km/h... but it's a great party. Also consider the night tour if it's still happening this year, it's pretty cool.
I usually live in Montreal but I am not in Vancouver for a couple of years for my PhD (and who knows where I'll be after!!). I will be back in Montreal this Summer, but not until July, unfortunately.
For future travel, I strongly recommend checking out "Le Grand Tour" (on the same web site as the Bike Fest, under Travel, you should find it easily). It's a wonderful ride with exceptional support, and great food, great parties, great people.
Send me a private message if you need any info on restaurants in Montreal, food is my forte.
Cheers!
