Worthwhile multi day hikes in Ontario?

Looking for some more/new to me multi day hikes in Ontario.

Have already done the following ones in the last couple of years:

– Killarney la cloche silhouette
– Ishpanina ridge
– heaven's gate trail

Considering doing some of the ones in Algonquin or bruce peninsula but am wondering if there are any others worth considering? The more off the beatten path the better

Thanks
