Interesting discussion......some points/questions.
do you know (I don't) what portion of Brampton's population works downtown? Why would it be "small"....anectdotally, the traffic on the "step ladder" of highways made up of the 410-401-427-Gardiner seems pretty busy.....I always assumed that there were others (others being a substitute for a large number I don't know) making a Brampton-DT Toronto commute.
How does Brampton slow down its growth? The province is actually encouraging it to grow further, the same province who control the purse strings on the highways and regional transportation that you/we/all acknowledge needs to improve. So what is a city of over 500k to do when the next tier of government wants it to get bigger but is reluctant to provide the tools to make the current population and it's encouraged growth workable/liveable?
Mississauga, Markham and Vaughan have more jobs than workers but Brampton has less jobs than workers....where do these numbers come from?
EDIT....it is also a bit of a dilema when told to attract new jobs....when one of the key factors in businesses (large) selecting a location is ease of mobility (people, goods, products) into and out of the chosen location.
Well first of all I don't think the province should encourage Brampton to grow so much, they should rather encourage Toronto, Markham, Vaughan, Mississauga and Oakville to grow a bit more. Brampton could also try to encourage what ever residential and commercial growth it does take on around GO Stations, the future Hwy 10 LRT and Zum to minimize the amount of additional traffic. This would be done by improving transit and zoning, and maybe creating public ammenities in these areas. I don't really have a plan for how Brampton could increase the amount of jobs it has, but if it can avoid too much additional traffic from residential/commercial, that should help make it more feasible for industry to locate there. On a related note, I'm not convinced encourage so much growth in Milton is good either, since it will likely increase congestion on the 401 and the place seems to have pretty hopeless transit.
As for how many people from Brampton commute to downtown Toronto, I'm not saying it's completely insignificant, but I'd guess maybe around 10% of Brampton workers? The vast majority work elsewhere.
Here's where it says Vaughan, Markham and Mississauga have more jobs than workers while Brampton has less:

I think most of the outer 905 has fewer jobs than workers. You can see that from 2001 to 2006 at least, Brampton has been becoming more and more of a bedroom community while Mississauga has been becoming more and more of a job centre. It's not that Brampton isn't adding a lot of jobs, it's just that the job growth isn't keeping up with population growth, Brampton's population is growing much faster than Mississauga's.
As for most of Brampton's residents working elsewhere than Downtown Toronto, Downtown Toronto has about 400,000-500,000 jobs, depending on how you define the area. The whole GTA has about 3 million jobs. If about 13-17% of GTA residents work in downtown Toronto, why would that percentage be higher for Brampton? The percent of Toronto residents working downtown is probably higher, since downtown is closer, which means the percent for certain suburbs is lower. I wouldn't be surprised if more people (in % terms) from Oakville, Richmond Hill, Georgetown or Aurora worked downtown Toronto than from Brampton. Downtown Toronto jobs are generally high paying jobs, the kind that residents from these wealthy suburbs would have. Brampton I suspect has a lot more people working in manufacturing and retail, and those jobs would mostly be in Brampton and other suburban areas.
This says roughly where Brampton residents work.
http://www12.statcan.gc.ca/census-r...&SearchType=Begins&SearchPR=01&B1=All&Custom=
In 2006...
31.7% worked in Brampton
26.6% worked in a different census division of Ontario, probably mostly Toronto and York Region and some in Halton Region
25.6% worked elsewhere in Mississauga and Caledon
11.4% had no fixed workplace address (I guess like truck or cab drivers, maybe construction and landscaping jobs would could too?)
4.1% worked at home
0.5% worked outside Canada
0.1% worked in another province
This is a map of where the jobs are in the Toronto MSA:
http://www5.statcan.gc.ca/access_ac...WorkplaceResidence/TorontoPOW_PowPor_ec-2.pdf
Seems like Milton has about 23,000 jobs to 28,000 workers
Halton Hills has 17,000 jobs to 27,000 workers
Caledon has 19,000 jobs to 28,500 workers
Oakville has 75,000 jobs to 92,500 workers
Richmond Hill has 59,000 jobs to 90,500 workers
Aurora has 20,000 jobs to 26,000 workers
King has 6,500 jobs 11,000 workers
Newmarket has 39,000 jobs to 41,000 workers
Orangeville has 12,000 jobs to 14,500 workers
So pretty much the pattern seems to be a deficit of jobs relative to workers in the outer 905 (which includes Brampton) and a surplus in the inner 905. The patterns is probably the same for the inner/outer 416, Old Toronto has a surplus of jobs, and Scarborough most likely has a deficit, hard to say for the rest.
