Videotron, like every other Canadian company it seems, wants to make it a bit (but not too) difficult to find their telephone number to speak to a real living person. Oh sure, they put the automated service phone number right at the top left of the page, but you have to click another link and scroll down to the bottom to find the page to find it.

So, here it is, all on one page:

Videotron Support Number for Residential Customer Service: 1-888-433-6876

The hours of service are:

M-F: 7:30 AM to 9:30 PM
Saturday: 8 AM to 6 PM

If you're in these areas, they save a bit of money if you use the local number:

Montreal: (514) 281-1711
Quebec City: (418) 847-4410
Saguenay: (418) 545-1114
Outaouais: (819) 771-7715

Videotron Technical Support Number: 1-877-380-2611

This number is available 24 hours a day, 7 days/wk.

Again, they'd probably like it if you use one of the following numbers if it is local to you:

Montreal: (514) 841-2611
Quebec City: (418) 842-2611
Saguenay: (418) 543-4611
Outaouais: (819) 771-2611

Be sure to investigate the other options you have available if you don't like Videotron, and even if you are, other options might be cheaper! Expressvu and Starchoice are available for TV, and tons of companies are available for DSL.
