Cost-Effective Shipping Options within Canada

Hey Folks,

First time asker/poster here.
I was wondering if anyone has recently shipped boxes/totes across Canada.

I'm currently in Calgary, moving back to Toronto and I want to ship 5-7 Totes, about 50lbs each.
Looks like Canadapost is quoting me 1-week deliveries per tote @ ~$60-70CAD Each.

On the other hand, I saw Shiptime, and they seem to be quoting cheaper using Loomis Express/Purolator.

I was wondering if y'all had better options/recommendations.
Also, has anyone used Shiptime before (as a Costco member)?

Thanks!
