Poor Network in my home area

Unfortunately, that likely also means that much of your nearby towers will still be predominantly Bell towers that Telus shares so Bell would maintain and configure them and Telus would need to pass along coverage issues, as most of Telus owned hardware would be in downtown T.O. or possibly in the highest traffic parts of Brampton.

You can still see what towers are in you neighbourhood via that map link above.

The issue with urban areas is bldg obstacles in addition to antenna angle placement. Also a lot of towers had 4G gear removed and redeployed to other locations to make room for 5G hardware sometimes causing little coverage holes where none existed before. Also there are other thing like signal bounce and freq overlap but those are rarer issues and usually in the densest of urban areas or near large emf generators.

Unfortunately consumer Femto cell deployment never really took off in N.Am, even in the US it's still mainly businesses that get that option even offered. The consumer side even for early advocates like AT&T (which I first saw a consumer option at CES in 2011) have offered, then discontinued, then offered solutions on&off with mediocre support or success, the 5G hit and the focus pivoted there. The Big3 in Canada played around with consumer femtocells around 2015/16/17 but it never took off, because ironically consumer coverage was good enough, and the gaps were mostly in areas where even internet was unavailable to fill that gap. Commercial solutions also didn't translate to consumer well. Whereas the US' patchwork offered a possibility of better adoption, but still didn't translate to it's widespread use.

Again, I would recommend looking at what hardware is near you and who owns it, whether or not a booster would help would depend on why your urban coverage is bad. A directional antenna & booster might help, but it still needs some signal to provide better signal, it doesn't work well on barely a single bar unless you have very clear line of sight.
