Prepaid Data SIM in Canada (WIND)
WIND mobile shops sell prepaid SIM with unlimited data plan.
It’s quite expensive though — $25 for a SIM card, $30 for Unlimited data/call/text for 30 days, with tethering. It will be throttled if you go over 5GB.
Might be reasonable if you stay for a few weeks. Or for months, that’d be a great deal. But for my 5 day stay, it felt very pricy, although i had no other options. (fido seems to have the similar options)
