Thanks for your input. Don't be shy about contributing to the forum.
The Canadian Tire rumour has been circulating for a few months (amongst other rumours). It's possible, but the most likely rumour at present is a call centre for TD Bank. TD had been waiting on renovations to MHS, but these are taking longer than expected to begin. I don't know if this is to be considered a permanent solution, or just a temporary one until MHS becomes available. In either event, using the space for a call centre would be most unfortunate.
Current possibilities for the old Sears space include (but are not limited to):
1) - TD Insurance customer contact centre (temporary or permanent) - most likely
2) - Canadian Tire (possible, but not the best fit for CF since they want Champlain to be a fashion mall)
3) - Simons (everyone's preferred choice, and remotely possible if they also set up in the old Sears space at Halifax Shopping Centre as well).
4) - Hudson's Bay Company (also a good fit for CF, but financial circumstances in the HBC chain make this unlikely at present)
5) - subdividing the space for other retailers/services like Rec Room, Indigo etc (probably the best long term option for CF).
My own opinion is that CF will let TD have the space for it's contact centre in the short term while they come up with a sustainable long term plan for the space.
