Calls from Stats Canada
They use a large range of numbers in their outbound calls.  Likely each and every desk in the call centre has it's own direct number.

All the numbers they have tried to get me with from my call logs:
"STATS CANADA" <7804953379>
"STATS CANADA" <7804953457>
"STATS CANADA" <7804953847>
"STATS CANADA" <7804954610>
"STATS CANADA" <7804954613>
"STATS CANADA" <7804954614>
"STATS CANADA" <7804954617>
"STATS CANADA" <7804954760>

Had enough of this monthly survey that wont accept "same as last time" as an answer

It's a legit call from Stats Canada; not a prank or spam, but their insistence is quite annoying.

As stated above, they have lots of numbers. These are the ones that called my cell:
(780) 495-6696
(780) 495-3457
(780) 495-3379
(780) 495-7844
(780) 495-2852
(780) 495-4760
(780) 495-7822

It's a real survey. When you answer, you can decline to take part in the survey.  They've been calling my cell in Vancouver for a few weeks now, but hadn't answered until now.  I hope that since I declined to take the 40 minute survey on my cell phone, that they will not call again.

They have been calling me at least twice a day for WEEKS. I finally relented and started the survey. After 30 mins we called it quits. Feeling quite harrassed snd unsatisfied by the whole experience. Tried to be a helpful citizen but felt like they took a mile.
